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 decennial census in the Arab Union. Respondents were able to submit their response as early as 1 January 2020, with census day falling on 10 January 2020, the last day on which responses could be submitted, with the tabulation, calculation and revision process finished and results published on 2 February 2020, the first Monday of the month. The 2020 census was conducted by the Central Bureau of Statistics, an independent agency of the government of the Arab Union.

This was the second decennial national census to include the option to respond online, in addition to traditional mail-in or in-person submission of a paper questionnaire, and the first allowing respondents to leave both "male" and "female" boxes unchecked and instead specify gender in writing, as opposed to previous editions which required choosing one. The 2020 census counted a total population of 558,319,377, representing an increase of nearly 14% from the 489,903,436 counted in 2010. The next all-union census will take place in 2030.
