2020 Arab Union census

The All-Union Household and Commercial Census of 2020 (Arabic: تعداد عموم الإتِّحاد للأسرة والتجارة لعام ٢٠٢٠ ta‘dād ‘umūm al-ittiḥād lil-asrah wat-tijārah li-‘ām alfayn wa-‘ashrūn) was the sixth national national census conducted by the federal government of the Arab Union. Census day was 10 January 2020, the last day on which responses could be submitted, with the calculation, organisation, and revision process finished and results published on 2 February 2020, the first Monday of the month. This was the second federal census in the country to include the option to respond online, in addition to the traditional mail-in or in-person submission of the paper questionnaire, and the first to feature a third "other" response option for the query on sex/gender.

Like the previous five editions of the census of 1990, 1995, 2000, 2005 and 2010, the 2020 census was conducted and administered by the Central Bureau of Statistics, an independent agency of the federal government funded by the Ministry of Trade. The census is supposed to be conducted quinquennially (that is, every five years); however, due to the 2011–19 civil war and incredibly difficult (if not impossible) task of producing an even semi-accurate census in wartime, in 2015 the census was decided to be postponed until the end of the war, which came shortly before the start of 2020. The next census is scheduled for 2025.
