The 2021 Population and Housing Census (Greek: Απογραφή Πληθυσμού–Kατοικιών 2021) is a census in Greece that was conducted by the Hellenic Statistical Authority as part of the wider 2021 European Union census. As with the 2011 census, it enumerates the number of people in the country and surveys the demographic, economic, and social characteristics of the population, as well as the types of building stock available in the country. The census complies with both European Union and United Nations census guidelines. The full set of results will be available by 31 March 2024.
Smartphone and geolocation technologies were utilized in order to carry out the census. A design competition was launched in September 2018, asking university students to design the census logo, and the winner was announced in 2019.
The final results of the census were announced on 28 December 2012, with a minor correction in 2014. According to final results, the total resident population of Greece was 10,815,197 on census day. There was a margin of error of 2.84%.
