Abstract
Volunteering offers young people valuable opportunities for personal and social development, yet social inequalities in access and participation persist. This study examines how ethnicity/migration background, gender and social status shape formal volunteering among Flemish youth, with special attention to how these characteristics intersect. Using survey data from students (age: 15â20) in urban areas and a rural control group (n = 2,354), we apply a multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIDHA) analysis and multilevel logistic models to analyse individual, intersectional and interaction patterns. Results show clear differences in formal voluntary engagement by migration background but no clear differences based on social status or gender. However, intersectional analyses nuance this general pattern, revealing barriers that remain hidden when characteristics are studied separately. By highlighting these intersectional dynamics, the study contributes to a deeper understanding of social inequalities in youth volunteering and underscores the importance of moving beyond single-axis analyses.
Introduction
Research consistently shows that participating in volunteer work positively affects young people. Volunteering is associated with improved physical and mental health, enhanced career opportunities and other forms of civic engagement (Moore & Allen, 1996; Musick & Wilson, 2008; Shaw & Dolan, 2022). Beyond these general benefits, volunteering is also expected to support specific groups, such as women (Moore & Allen, 1996) or migrants (Ambrosini & Artero, 2023), by enhancing their professional status and bridging cultural divides (Moore & Allen, 1996).
Given this positive impact of volunteering, it is important to examine the social disparities in access to and opportunities for participation. This study specifically investigates which social groups among Flemish youth engage in formal volunteering, defined as volunteering within the context of an organization. More specifically, we focus on the (complex) interplay between differences based on ethnicity/migration background, gender and social status. Unlike previous research, we place greater emphasis on how combinations of these characteristics relate to volunteering among young people. This intersectional approach aims to identify barriers that are overlooked in one-dimensional analyses.
To map the various social differences in formal voluntary engagement among Flemish young people, we utilize data from the 2023 JOP (Youth Research Platform) Urban Youth Survey (n = 2,354). In these data, young people attending secondary school in urban areas of Antwerp, Ghent and Brussels are overrepresented, resulting in a very diverse sample. The analyses reveal clear differences in formal voluntary engagement based on ethnicity/migration background and social status, but not on gender. However, in-depth analyses show that this general pattern requires further nuance when combinations of characteristics are taken into account.
Literature Review
Although youth volunteering has received increasing scholarly attention, there remains a lack of quantitative research adopting an intersectional perspective. This literature review begins with a theoretical review of three key social characteristics that previous research has identified as shaping access to volunteering: migration background/ethnicity, gender and social status. This focus is informed by the work of Mary Jackman (1994), who argues that, despite their idiosyncratic elements, these characteristics share a common feature: they all refer to relationships of dominance. These are relationships in which one group (i.e., men, high class and natives) historically had a structural and often institutionalised advantage over the other group (i.e., women, lower class and immigrants). While these characteristics are usually analysed separately, our analysis explicitly considers how they may interact and how such intersections may amplify or mitigate their individual effects on participation in formal engagement. We therefore continue with a conceptual discussion of âintersectionalityâ and how the three key social characteristics might interact.
Migration Background
The first social factor examined in this article is migration background. Although research indicates that formal volunteering can help bridge cultural divides between individuals with and without a migration background, people with a migration background are often underrepresented in formal volunteering (Siongers & Spruyt, 2025). This underrepresentation can follow from two different mechanisms.
First, the act of migration itself can negatively affect formal voluntary engagement (Ambrosini & Artero, 2023; Musick & Wilson, 2008). First-generation migrants often have smaller social networks, as they leave behind established connections and require time to build new ones in the host country (Ambrosini & Artero, 2023; Southby & South, 2016). A smaller social network reduces the likelihood of being introduced to individuals already active in volunteering and, as such, also to voluntary work and organizations. In addition to smaller social networks, first-generation migrants also face various barriers to volunteering, such as language difficulties and limited familiarity with the cultural norms that shape organizational life (Cappelletti & Valtolina, 2015).
A second strand of literature argues that sociocultural differences and the deprivation or discrimination that people with a migration background face hinder their voluntary engagement. This applies not only to first-generation migrants but also to secondâand possibly furtherâgenerations (Hunkler et al., 2015). A crucial finding here is that many individuals begin volunteering because they are invited to do so, rather than initiating it themselves (Bekkers et al., 2016). People with a migration background are often not regarded as perfect volunteers and are therefore less frequently asked to volunteer (Southby & South, 2016; Sundeen et al., 2007). These socio-ethnic differences in being recruited are also likely to vary by the specific country of origin, given that discrimination (one but not the only cause) has been shown to vary by the country of origin, with often a European/non-European divide in discrimination in European countries (Acolin et al., 2016; Ghekiere et al., 2023). Moreover, taste-based discrimination also often differs in terms of countries of origin, with those with a European background often facing less discrimination than those with a non-European background (Ghekiere et al., 2023).
Additionally, the culture of a migrantâs home country can affect their attitudes towards volunteering (Randle & Dolnicar, 2009). Cultural norms may influence the willingness to participate, with different ethnocultural groups viewing volunteering and helping others in unique ways (Falzarano et al., 2022; Randle & Dolnicar, 2009). Hofstede (1980) differentiates between individualistic and collectivist societies, noting that individualistic cultures may value volunteering less. In Belgium, the individualism difference between Moroccan (more individualistic) and Turkish (more collectivist) communities is well documented (Lesthaeghe & Surkyn, 1997).
Besides general cultural differences, country-specific variations in volunteering rates exist among Belgiumâs largest migrant groups from TĂŒrkiye, Morocco, Poland, Congo and Mediterranean countries. Research by Aslan and Tuncay (2024) indicates low volunteering rates in TĂŒrkiye, with limited national promotion. Belgiumâs neighbours have similar voluntary engagement levels, suggesting comparable attitudes (Enjolras, 2021). Poland and Mediterranean countries rank low, indicating hesitancy towards formal volunteering (Charities Aid Foundation, 2023; Nakamura et al., 2025). No current data are available for Morocco and Congo (UN Volunteers, 2026).
To sum up, we expect differences not only by young peopleâs migration status but also by the country of origin/background. Hesitant or adversarial attitudes towards volunteering in one culture might thus lead to lower volunteering rates among migrants from that culture in another nation that is more open to volunteering.
Gender
There is no consensus on gender differences in (formal) voluntary engagement. Some studies suggest an overrepresentation of men, while others indicate an overrepresentation of women (Musick & Wilson, 2008; Wymer, 2012), and yet others find no gender differences (Siongers & Spruyt, 2025). Gender differences are more likely to be found in specific contexts of voluntary engagement (Einolf, 2011). For example, research shows that in some organizations, such as fire stations, men are overrepresented, while women are more likely to volunteer in organizations involved in care tasks (Einolf, 2011; Musick & Wilson, 2008). Gender differences are also found within organizations based on the division of labour: men are often assigned technical or prestigious roles, whereas women are more frequently allocated caregiving and administrative tasks (Rotolo & Wilson, 2007).
Various explanations have been proposed for these differences, in access to both volunteering and task distribution. A first explanation refers to the strong link between altruism, volunteering and charitable giving, with women consistently scoring higher on altruism and generosity (Musick & Wilson, 2008; Simmons & Emanuele, 2007). Among young people, girls tend to embrace more prosocial values and do so at a younger age, which may lead to higher volunteer participation (Beutel & Johnson, 2004).
Second, women generally have closer and stronger social networks than men (Blyth & Foster-Clark, 1987). Since being invited is a key factor in volunteering (Bekkers et al., 2016), stronger networks increase the likelihood that (young) women are asked to participate and encouraged to do so (Wymer, 2012).
A third relevant explanation relates to household and care tasks. Women and girls continue to perform a disproportionate share of household work (Herd & Harrington Meyer, 2002; Mullens & Glorieux, 2019; Putnick & Bornstein, 2016). The implications for volunteering are twofold. On the one hand, according to the time-scarcity hypothesis, increased domestic responsibilities reduce the time available for volunteering (Herd & Harrington Meyer, 2002; Mullens & Te Braak, 2023). On the other hand, household and care responsibilities can lead to increased voluntary engagement. Gendered socialization may promote care-taking behaviour in girls, encouraging both informal and formal voluntary engagement (Musick & Wilson, 2008; Simmons & Emanuele, 2007; Wuthnow, 1995).
Taken together, these divergent mechanisms may cancel each other out, which could explain why some studies find no significant gender differences in volunteering.
Social Status
In this article, social status refers to the socio-economic position of young people, reflecting their standing in society, and is defined in broad terms. We use the term as having two components: a material and a cultural component. For young people, social status is measured by their parentsâ income (material component) and their educational track as a cultural component. While parental income is an ascribed characteristic beyond the young peopleâs control, the educational track is considered a (partly) acquired one. Despite persistent patterns of social reproduction in Flanders (and hence a strong link between parentsâ education and young peopleâs track position; see Elchardus et al., 2013), it is ultimately the young person who navigates their educational trajectory (Lagaert et al., 2024).
Educational attainment is one of the strongest predictors of participation in voluntary work (Boraas, 2003; Musick & Wilson, 2008). Differences based on education are often attributed to social networks and to being âaskedâ to volunteer, two factors already discussed. According to the so-called relative education model, it is not the specific knowledge and skills acquired that explain differences in voluntary engagement among young people, but rather the social-network position education affords. Organizations tend to recruit volunteers from individuals who occupy central positions within social networks. Educational status plays a key role in securing that centrality (Persson, 2011), and this especially applies in countries with a highly tracked secondary education, such as Flanders. Research shows, for example, that in Flanders, young peopleâs social networks (including friendships) are strongly segregated by educational tracks and that young people who follow vocational education experience track-based stigma (Spruyt & Van Droogenbroeck, 2024). This social status not only increases the likelihood of being asked but is also linked to what Lareau, following Bourdieu, calls a âsense of entitlementâ (Golann & Darling-Aduana, 2020; Lareau, 2011). Young people from higher socio-economic backgrounds are more likely to pursue general secondary education, which not only confers higher status but also offers access to broader networks and greater institutional experience. In this way, the educational track serves as a key channel through which social status translates into differences in voluntary engagement.
In terms of material resources, income may also influence volunteering. The dominant status theory holds that dominant groups in society are more likely to volunteer. Dominant groups often possess more economic, social and cultural resources, which can be attributed to volunteer work (Hustinx et al., 2022; Musick & Wilson, 2008). Furthermore, these groups are seen by volunteering organizations as more desirable than those with fewer economic, social and cultural resources (Hustinx et al., 2022). This means that the economic status often provides access or barriers to entry into volunteering organizations.
A second way the economic aspect of social status might affect young peopleâs odds of volunteering is through the time-scarcity hypothesis. With part-time work becoming more prevalent among Belgian youth, there may be less time available for voluntary activities (Spruyt, 2024). Furthermore, part-time work is more prevalent in low-income households (Spruyt, 2024), suggesting that young people in low-income households might spend more time on income-generating activities than on unpaid, voluntary activities.
Intersectionality
In this article, we not only focus on the relative importance of each characteristic. We are primarily interested in assessing the relevance of the combinations of these characteristics. Crenshaw (1991) first introduced the concept of intersectionality to describe how multiple identities intersect and create new forms of discrimination or disadvantage.
Since its introduction, the concept of intersectionality has been further developed and broadened and is no longer limited to gender and ethnicity. Intersectionality can be understood as the intersection of different forms of inequality and exclusion, such as racism, sexism and class discrimination (Combahee River Collective, 1977; Wekker & Lutz, 2001). The central idea is that different axes of inequality also lead to interlinked systems of oppression and exclusion (Collins, 1993). In this contribution, we adopt an intersectional perspective to examine access to and participation in volunteering.
There is growing evidence that an intersectional approach provides valuable insights into inequalities in voluntary engagement. Many studies have shown that the intersection of different identities creates unique positions regarding volunteering. For example, Musick and Wilson (2008) found that higher income promotes volunteering among white Americans, but not for black Americans. Musick and Wilson (2008) show that status differences are often reinforced by peopleâs ethnicity. One might even expect that both characteristics (i.e., migration background and social status) reinforce one another as volunteer organizations frequently continue to associate the ideal volunteer with individuals who possess high levels of social capital, such as the highly educated and native-born. Those who deviate from this profile face reduced opportunities to engage in voluntary work.
Beutel and Johnson (2004) found a difference in prosocial values, an important predictor of volunteering, between white boys and girls, but not between black boys and girls. This finding suggests that gender differences may become salient in interaction with other social factors, such as ethnicity. Research has shown that the effect of gender on volunteering varies by respondentsâ ethnocultural background in the United States (Bellido et al., 2021) and that gendered participation in leisure organizations varies across ethnocultural backgrounds (SchaillĂ©e & Theeboom, 2014).
With this in mind, this article aims to supplement existing research in two ways. First, it highlights the need for more data on how identity characteristics interact in accessing volunteering, supporting an intersectional perspective. Second, while most intersectionality research relies on qualitative methods, this study deliberately adopts a quantitative approach. Unlike most qualitative intersectionality research, this study uses a quantitative approach to demonstrate that the interplay of characteristics should be evident from large-scale, representative data. At its core, the intersectional approach rests on the idea that the âeffectsâ of separate characteristics cannot be isolated from those of other characteristics. Translated in quantitative terms, this should mean that one finds at least some meaningful significant interaction terms, as these imply that the effect of one characteristic moderates the effect of another.
Summary and Expectations
Drawing on previous literature, we expect to find (a) social differences in young peopleâs participation in formal volunteering and (b) that characteristics such as gender, migration background and social status will reinforce or weaken each otherâs effects.
Literature indicates that social factors, including migration background, influence young peopleâs volunteering. Migration-related factors, such as limited social networks and intergroup dynamics, including prejudice, are expected to negatively affect formal volunteering among youth (Ambrosini & Artero, 2023; Hunkler et al., 2015; Musick & Wilson, 2008; Sundeen et al., 2007). These effects are anticipated to vary across ethnicâcultural groups due to differing migration histories and perceived discrimination levels (Ambrosini & Artero, 2023; Hofstede, 1980; Musick & Wilson, 2008; Randle & Dolnicar, 2009). We therefore expect that having a migration background negatively affects young peopleâs odds of formal volunteering, with variation across countries of origin. Research shows a clear European/non-European distinction in discrimination at institutional entry points (Acolin et al., 2016; Ghekiere et al., 2023), suggesting that European respondents may face fewer negative effects than those from Maghrebi, Middle Eastern or Sub-Saharan backgrounds. Additionally, volunteering rates are expected to influence these effects; youth from countries with rates similar to Belgiumâs may not experience negative effects, while those from countries with lower rates might.
Regarding gender, we do not expect a general gender difference in participation, as counteracting mechanisms (e.g., prosocial attitudes vs time constraints) may cancel each other out, consistent with earlier findings (Einolf, 2011; Musick & Wilson, 2008; Siongers & Spruyt, 2025; Wuthnow, 1995).
We further expect young people with a higher social status to volunteer more than those with a lower social status. Because the literature holds that those in more privileged social positions, based on both education and income, will be regarded more as the âideal volunteerâ by organizations, they will have higher odds of formal volunteering than those in less-privileged social positions (Boraas, 2003; Golann & Darling-Aduana, 2020; Lareau, 2011; Musick & Wilson, 2008).
Furthermore, we expect that the intersection of migration background, social status and gender will also affect young peopleâs likelihood of engaging in formal volunteering. Previous research suggests that status effects may be intensified by migration background (Musick & Wilson, 2008) and that gender might constitute a double jeopardy for those with other discriminated identities (Beutel & Johnson, 2004; Musick & Wilson, 2008).
Based on the dominant status theory, we expect that young people in an underprivileged social position will experience negative effects on their chances of volunteering (Hustinx et al., 2022; Musick & Wilson, 2008). This suggests that young people with lower social status and those with a non-European migration background will face a double jeopardy for their precarious identities, which will decrease their volunteering. Furthermore, gender effects may interact with migration background, as cultural background influences gender disparities in volunteering (Bellido et al., 2021). Because this research was conducted in the American context, we find it prudent not to expect the same outcomes. We do, however, expect an interaction effect between gender and migration background, but cannot, in good conscience, predict its exact direction.
Methods
Data
To answer our research questions, we use data from the JOP Urban Youth Survey collected in 2023 among pupils in Flemish secondary schools. The survey placed specific focus on schools in the urban areas of Antwerp, Ghent and Brussels, three of the regionâs most urbanized and diverse cities in Flanders (the Dutch-speaking part of Belgium), with a control group for the rest of Flanders. Data collection was conducted digitally, using tablets provided in participating schools. A total of 5,550 young people participated in the survey (2,875 girls and 2,675 boys) with a school-level response rate of 28.1%. To ensure the data setâs representativeness, post-stratification weights were applied (Lagaert et al., 2024). These weights were calculated based on population statistics for the 2022â2023 school year gathered by the Flemish Department of Education (October census). Both the urban sample and the control group for the rest of Flanders were weighted separately by gender, grade and educational track. Greater or lesser weight was assigned to the responses of certain individuals, depending on the under- or overrepresentation of that group in our sample relative to the proportions in society (Lagaert et al., 2024). In the multilevel analysis, post-stratification weights were applied at the individual level to ensure that parameter estimates accurately reflect the population distribution and to account for clustering within schools. Urban oversampling increases the precision of estimates for students from metropolitan areas without biasing associations after applying weights. This allows weighted results to be validly generalized to all students in Flanders, both urban and non-urban.
Two additional selections were applied. First, only respondents aged 15 or older were included in analyses related to formal volunteering, as this is the minimum legal age for such activities in Belgium. Second, to avoid treating young people with a migration background as a homogeneous group, we disaggregated this group based on the country or region of origin. To ensure sufficient statistical power and meaningful interpretation, only countries/regions with adequate sample sizes were retained in the analysis.
After applying these selections, the final sample comprises 2,354 young people (1,268 girls and 1,086 boys; mean age = 16.4).
Measures
Volunteering
In this study, we focus on young people who participate in formal forms of voluntary engagement, which refers to volunteering activities done within the context of an organization (Hustinx et al., 2022). In our survey, respondents were asked to indicate which of the following activities they had done in the past 12 months. Respondents could select multiple answers:
Worked as a volunteer for one or more organizations (e.g., leading a youth club, helping in a charity) or events (e.g., at a music festival or a sporting event) Helped people in their community who do not live in their household (e.g., family members living elsewhere, neighbours, friends, acquaintances, strangers) Helped a co-residing family member who requires assistance due to a mental or physical illness or disability Helped their parent(s) with their business None of the above
If respondents selected the first answer, they were counted as formal volunteers. Based on this definition, 24.3% of the respondents in our sample reported volunteering in the past 12 months.
Socio-demographic Variables
We classify young people as having a migration background if they or at least one of their parents were not born in Belgium (Centraal Bureau voor de Statistiek, 2025). The country of origin assigned to young people was determined by their motherâs nationality at birth. If the mother held Belgian nationality at birth and the father held a different nationality, the fatherâs nationality was used to determine the migration background.
To focus on the main migrant groups in Belgium and to ensure sufficient statistical power and meaningful interpretation, this analysis includes only young people from neighbouring countries (the Netherlands, France, Luxembourg), Mediterranean countries (Italy, Spain, Portugal), Congo, TĂŒrkiye, Morocco and Poland. These countries were chosen based on both the size of the respondent group in our data and the theoretical consideration that they are the most important countries of origin for migrants to Belgium over the last few decades (Statistiek Vlaanderen, 2025). Young people (n = 781) from other countries were excluded due to heterogeneity and limited sample sizes within this residual category. As a result, our sample consisted of 66.3% young people without a migration background (n = 1,561). In addition, 4.9% came from neighbouring countries (n = 115), 6.6% had a Turkish background (n = 156) and 15.3% had a Moroccan background (n = 360). Young people with Congolese (2.6%; n = 60), Polish (2.1%; n = 49) and Mediterranean (2.2%; n = 52) backgrounds were a smaller group within our sample.
Because the number of respondents from specific countries of origin was limited, resulting in a lack of statistical power, we constructed two versions of the migration background variable. First, migration background was operationalized as a categorical variable distinguishing between young people with and without a migration background and those with a European or non-European background. Second, it was operationalized as a categorical variable distinguishing between young people based on the country of origin (seven categories).
Gender was included as a dichotomous variable (46.1% boys, 53.9% girls). The 36 respondents who did not identify with either category were excluded from the analysis, as the group was too small to make reliable statements.
Social status was operationalized as a combination of young peopleâs educational position and their familyâs subjective income. Subjective income was measured by the extent to which young people felt their families could make ends meet with their available monthly income. The five response categories ranged from âvery difficultâ to âvery easyâ. If young people indicated that their family could get by easily or very easily, they were categorized as the high-income group. If they indicated they could get by reasonably easily, or if it was hard for them to get by, they were considered part of the low- to medium-income group.
Educational position was based on the educational track in which young people were enrolled. In the Flemish education system, there are three main educational tracks: general, technical and vocational. General education prepares students for higher education. Vocational education prepares students for entry into the labour market. Technical education provides access to both pathways. These different educational pathways differ not only in their finality but also in their social prestige (Spruyt & Van Droogenbroeck, 2024), with vocational education generally considered less prestigious. Moreover, the social reproduction of educational inequality is high due to the early tracking system (Dekeyser, 2024). In practical terms, this means that there is strong relationship between parentsâ educational position (often seen as an indicator of cultural capital) and young peopleâs track position.
Social status was determined by combining young peopleâs educational track and subjective income and categorizing them into four groups: high, mid-high, mid-low and low. Respondents were categorized as having a high social status when they followed a general education and had a high income. If they followed a general track and had a low to medium income, or followed a technical track and had a high income, they were categorized as having a mid-high social status. Young people with a mid-low social status were those following a technical track without a high income and those following a vocational track with a high income. Young people in vocational education with a low to medium income were assigned a low social status. Table 1 shows the frequencies of all variables used in our study.

Statistical Analysis
In this article, we examine social differences in participation in formal engagement among youth and how these differences either reinforce or mitigate one another. Studying interactions between different variables provides insights into which social characteristics jointly shape voluntary engagement. However, using interaction terms can quickly become complex and difficult to interpret, particularly when it requires including not only two-way interactions but also three-way and higher-order interactions (Gelman & Hill, 2006). Therefore, in a first step of the analysis, we conduct a newer methodological approach called (I-) MAIHDA, or (intersectional) multilevel analysis of individual heterogeneity and discriminatory accuracy. This approach was developed to address the limitations of specifying interaction terms, providing a more efficient and interpretable framework for intersectional quantitative research (Evans, 2015; Evans et al., 2024). While this new approach addresses some limitations of interaction models, criticisms of the MAIHDA approach persist. First, researchers state that the possible built-in collinearity between the first and second levels, and the lack of a clear indication of the negative or positive nature of the intersection effect, make interaction terms still a justified method for studying intersectionality (Lizotte et al., 2020). Second, the MAIDHA model is based on defining all possible combinations of the characteristics (which are considered as a separate level). This can only be done when we use the three-category operationalization for young people with a migration background as a more refined operationalization would lead to the problem of too many sparse cells (Evans et al., 2024). These two elements led us in a second step to complement the MAIDHA analysis with a logistic multilevel regression model with specific interaction terms.
The MAIHDA approach uses multilevel modelling to examine inequality across multiple strata, which comprise multiple crossed categories of identities or contexts (Evans et al., 2024). In this research, we will use the MAIHDA approach to examine the effects of the intersections of gender, migration background and social status on young peopleâs formal volunteering. MAIHDA models aim not to capture interactions but to capture the effect that occupying a specific social position has on an individual by specifying a multilevel model in which individuals are placed at the first level, and the social stratum to which they belong is placed at the second level (Evans, 2015; Evans et al., 2024).
In our study, individuals are already nested in schools. We therefore employ a cross-classified multilevel model in which individuals are simultaneously nested within two independent (i.e., non-nested) second-level clusters: schools and social strata. Because schools and social strata are not nested within one another, each individual belongs to a unique combination of both factors (Snijders & Bosker, 2012). To account for the effects of both school membership and social stratum on individual outcomes, the combined contribution of schools and strata must be treated as the total variation (Hox et al., 2018). Therefore, a cross-classified logistic MAIHDA model was specified with formal volunteering as the binary outcome variable, and gender, social status and migration background as predictors. Variance was estimated at two levels, namely schools and social strata.
In a first set of analyses (Table 2), which we will call the MAIHDA model, a null model was estimated to assess the baseline variation between schools and strata. In Model 1, the key predictorsâgender, social status and migration backgroundâwere added. Because the number of respondents is too low for our sample to be divided by the country of origin, we chose to create 24 strata based on young peopleâs gender (two categories), social status (four categories) and migration background (three categories). This adjusted model allows us to examine the contribution of these predictors and to evaluate how much of the variance between social strata is explained by their inclusion.
Cross-classified Intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (n = 2,354).
Since we found that looking at the migration background in broad categories, such as distinguishing only between people with European and non-European migration backgrounds, is reductionist, we chose to further deepen our analysis by also examining the effects of different countries of origin. In the second set of analyses (Table 3), called the interaction model, we further split the migration background into a categorical variable with seven categories based on the country of origin. We conduct a multilevel logistic regression analysis with interaction effects for the different predictors: gender (two categories), social status (four categories) and migration background (seven categories). In each model, we added an interaction term between two of the three core characteristics: gender, migration background/ethnicity and social status. We did not include a model with three-way interactions because the size of our sample leads to sparse cells.
Results
The null model (Table 2) indicates that 5.49% of the variance in the propensity for formal volunteering is attributable to differences between schools. However, these school differences are not the primary focus of this study. Model 0 (Table 2) further shows that 5.25% of the variance in formal volunteering is attributable to differences between intersectional social strata.
In the adjusted model (Model 1, Table 2), the inclusion of gender, social status and migration background reduces the stratum-level variance from 5.25% to 2.79%. The proportional change in variance (PCV) shows that 48.10% of the intersectional clustering (between-strata variance) observed in the null model is attributable to the additive effects of gender, social status and migration background. The remaining variance (2.79%) is relatively small, suggesting that there is limited evidence for substantial non-additive or intersectional effects beyond these main effects.
This model, furthermore, shows that, as expected, gender is not a significant predictor for young peopleâs formal engagement. Similarly, no significant differences are observed across social status groups. We do, however, find that young people with a non-European migration background have lower odds of participating in formal volunteering than those without a migration background. Young people with a European migration background do not differ significantly from people without a migration background.
While the MAIHDA results indicate that most of the variation in formal volunteering is attributable to additive effects, the remaining unexplained variance is small, and MAIHDA does not identify which specific combinations of characteristics drive these differences. Moreover, the use of broad migration categories may obscure heterogeneity between more specific groups. Therefore, additional models including interaction terms and more fine-grained migration categories are estimated to assess whether particular combinations of characteristics deviate from additive expectations.
In the interaction model, both Model 1a and Model 1b (Table 3) show that, as already indicated by the MAIDHA model, there are no significant gender differences in the uptake of formal engagement. We do, however, find that having a mid to low social status negatively affects the odds of a person volunteering. This effect was not significant in the MAIHDA analysis. However, when comparing the odds ratios in the MAIHDA (odds ratio, 0.780) and in the interaction model (OR: 0.739; 0.740), we find that the effect sizes are broadly comparable across the models.
Multilevel Logistic Regression Model with Interaction Effects (Alternative for Migration Background) with Only the Significant Interaction Effects (n = 2,354).
The analyses show that the odds of participating in formal volunteering are significantly lower for young people with a migration background (Model 1a). Respondents with a migration background from both European (OR: 0.692) and non-European (OR: 0.739) countries have lower odds of formal volunteering. When we examine the specific countries of origin, we find that young people with a Congolese (OR: 0.402), Turkish (OR: 0.430) or Moroccan (OR: 0.566) background have lower odds of volunteering compared with those without a migration background (Model 1b). In the model that differentiates formal volunteering by the country of origin, only countries outside Europe show significant negative effects. This is comparable to the significant negative effect of having a non-European migration background found in the MAIHDA analysis. In the interaction models (Models 2â5), we find that, in particular, having a Turkish migration background remains a negative main predictor of young peopleâs formal volunteering. To better understand these differences, we conducted a robustness check, which revealed that religion cannot explain this significant difference (see Appendix A).
To deepen the MAIHDA results and examine potential interactions among the three characteristics central to this study (gender, social status and migration background), additional models (Models 2â5) were estimated. Each model included one two-way interaction term (Table 3). These analyses revealed three significant interaction patterns. First, a significant interaction was found between being a woman and having a mid to low social status (OR: 0.569). Gender also shows a main effect in the interaction model, suggesting that mid to low social status may attenuate the positive effect of being a woman.
When looking at migration status more broadly, we see that, in the interaction model, only having a Moroccan background negatively lowers the odds of a young person volunteering (OR: 0.569). We do, however, find two significant interactions with having a migration background. Having a Turkish background deepens the negative effect of low to mid social status (OR: 0.169). On the contrary, having a mid to high social status softens the negative effect of having a Moroccan background (OR: 2.599)
Discussion and Conclusion
In this study, we examined how social characteristics (social status, gender and migration background) are related to formal voluntary engagement among Flemish young people. Adopting an intersectional perspective, we focused not only on the individual effect parameters of these variables but also on how their combinations interact to shape patterns of engagement. Three key findings emerge from our analyses.
First, our results indicate that differences in formal volunteering are mainly driven by migration background. In particular, young people with a non-European migration backgroundâTurkish, Moroccan or Congolese descentâhave lower odds of formal volunteering. This finding confirms our expectation that a non-European migration background is negatively associated with young peopleâs formal volunteering. Despite lower individualism scores for Morocco and TĂŒrkiye than for Belgium, based on Hofstedeâs (1980) framework, young people with a cultural origin from these countries do not volunteer more, suggesting that cultural or religious explanations might not fully account for these differences. Instead, structural factors such as discrimination and unequal opportunities are likely to play an important role since people originating from European countries are found to face less discrimination and might therefore face fewer barriers than those from Maghreb, Middle Eastern or Sub-Saharan descent (Morocco, TĂŒrkiye and Congo) (Acolin et al., 2016; Ghekiere et al., 2023). In addition, differences in volunteering traditions across countries of origin may also contribute to these patterns. By contrast, gender and social status play a more limited and context-dependent (see also our third point) role. No consistent main effects are found in the analyses, although some effects of social status emerge in the multilevel models. In the base model, without interactions, having a mid-low social status negatively affects a young personâs odds of participating in formal volunteering, which is in line with our expectation. However, while the literature suggests that individuals in more privileged social positions are more likely to be seen as âideal volunteersâ and therefore participate more (Boraas, 2003; Golann & Darling-Aduana, 2020; Lareau, 2011; Musick & Wilson, 2008), it offers limited insights into why those with lower social status do not volunteer significantly less.
Second, the MAIHDA analysis shows that only a small proportion of the variance observed in formal volunteering can be attributed to intersectional (non-additive) differences between social strata. This indicates limited evidence for strong intersectional structuring in this context. Rather, most observed differences can be explained by additive effects, particularly those related to migration background. These findings caution against overstating the role of intersectionality at the population level in explaining inequalities in youth volunteering.
Third, the interaction models show that some effects depend on specific combinations of characteristics. For instance, the positive association often found for girls is counteracted by the negative effect of having a (mid-)low social status, suggesting that social status is more decisive in predicting young peopleâs voluntary engagement. Gender effects might thus be context-dependent, as was stated in previous research (Einolf, 2011; Musick & Wilson, 2008; Siongers & Spruyt, 2025; Wuthnow, 1995). Furthermore, social status also interacts with migration background. The effect of having a Turkish background is amplified by lower social status, while the negative effect of having a Moroccan background is mitigated by higher social status. This confirms our expectation that having two identities associated with lower social status will create a double jeopardy for young peopleâs volunteering efforts (Hustinx et al., 2022; Musick & Wilson, 2008). These patterns suggest that, although intersectional effects are not dominant overall, certain subgroups may still experience differentiated outcomes that are not fully captured by additive models.
However, our research has some limitations. First, we had a lower response rate than anticipated. Based on the responses received from the schools, several explanations were cited, including the high number of requests to schools to participate in research, the recent COVID-19 pandemic and associated learning deficits, teacher shortages and the increasing (administrative) pressure on teachers, school staff and school boards (Bradt, 2024). This dropout, however, was not selective, and the low response rate is not reflected at the respondent level. Furthermore, to conduct intersectional analyses in our research, we chose to use the MAIHDA analysis, which still has some limitations. Because it does not give clear indications of the nature of the interaction effects, and because we could not disaggregate the groups we would have hoped, we needed to also include a second logistic regression model with interactions to alleviate some of these limitations, but which also made the analysis less straightforward and leaves the intersectional effect not fully explained. A final limitation is our operationalization of social status, which might have stronger effects if it had also included parental education or occupation as a variable. This might also shed light on the different effects of status found in the MAIHDA and the logistic regression model.
Our findings also point to the need for further research. Despite growing interest in youth volunteering, the mechanisms underlying unequal participation remain insufficiently understood. Qualitative research could provide valuable insights, for instance, into how organizations manage diversity and whether (often implicit) barriers exist that limit participation among certain groups. Our study highlights that having a non-European migration background is the main predictor of lower volunteering rates among youth and that young people with a migration background cannot be seen as a homogenous group. Ethnocultural background is an important factor in whether a young person decides to volunteer. Organizations should thus critically examine their recruitment and inclusion practices, recognizing their potential to either reinforce or alleviate disparities in youth volunteering.
Taken together, our findings suggest that inequalities in youth volunteering are best understood as primarily additive, with selective interaction effects rather than as strongly intersectionally structured. This implies that while an intersectional perspective remains useful, its added value in this context lies mainly in identifying specific subgroup differences rather than in explaining broad patterns of inequality.
