Abstract
This paper presents the evolution of the Greek statistical system and the journey towards the ``professional independence and accountability of statistical agencies'' which, according to the preamble of the resolution adopted by the United Nations General Assembly on the ten Fundamental Principles of Official Statistics, are imperative for ensuring public trust in the integrity of official statistical systems and confidence in official statistics. Also, the individual contribution of the United Nations experts for the establishment of the modernized statistical agency during the 1950s and 1960s is recorded and a brief history of the census is presented.
