The 2020 CPH is the country’s 15th Census of Population and 7th Census of Housing since 1903. Like previous decennial censuses, it is aimed at taking an inventory of the total number of persons living as of 12:01 AM on 01 May 2020 in the 17 administrative regions of the country. It also includes Filipinos in Philippine embassies, consulates, and missions abroad. Data generated from censuses are used in decision-making for good governance, development planning, risk reduction and crisis response, social welfare programs, and business market analyses, among others.
The CPH was conducted amidst the Coronavirus disease 2019 (COVID-19) pandemic in September 2020. Despite the added challenge and threat in our health during data gathering, the activity received overwhelming support and response from partner agencies, both local and private sector, particularly the LGUs and the public.
