The 2020 CPH was undertaken by the Philippine Statistics Authority pursuant to Republic Act No. 10625, also known as the Philippine Statistical Act of 2013, Executive Order No. 352 – Designation of Statistical Activities That Will Generate Critical Data for Decision-Making of the Government and the Private Sector, and Batas Pambansa (BP) Bilang 72, which provide the basis for the decennial conduct of the integrated census of population and housing.

May 2020 was declared as the National Census Month pursuant to Proclamation No. 928, s. 2020, which provided that the 2020 CPH be conducted in May 2020, with 01 May 2020 as the census reference date. However, in light of the Coronavirus disease 2019 (COVID-19) pandemic, the census enumeration was moved to September 2020. Information on the count of the population was collected with 12:01 AM of 01 May 2020 as the reference time and date, in accordance with the provisions indicated under BP 72.

President Rodrigo Roa Duterte has declared official for all purposes the population counts by province, city/municipality, and barangay based on the 2020 CPH under Proclamation No. 1179 dated 06 July 2021. The population counts were based on census questionnaires administered by about 6,218 enumerators deployed by the region during the nationwide census taking.

The successful completion of the census-taking amidst the COVID-19 pandemic would not have been possible without the cooperation and support of the census respondents and barangay officials regionwide. The PSA V would also like to thank the members of the local census coordinating boards, officials of national government agencies and local government units, media practitioners, private agencies, non-government organizations, homeowners’ associations, building administrators, and all other census stakeholders. Credits also go to the thousands of enumerators, supervisors, and other census workers hired by PSA V for the 2020 CPH.
