# 2020 Philippine census

The 2020 Census of Population and Housing (CPH) was the fifteenth census in the Philippines and the second census conducted by the Philippine Statistics Authority (PSA).

## Pilot run

The Philippine Statistics Authority (PSA) conducted a pilot run of the census from May 20 to June 17, 2019 covering eight areas. A new computer-aided system was tested, with PSA personnel to use an electronic questionnaire through digital tablets.

## Postponement

The census was originally scheduled to start on May 4, 2020. The conduct of the census was postponed due to the COVID-19 pandemic. The census was planned to be held sometime after the lifting of the enhanced community quarantine in Luzon which was imposed as a response to the health crisis. The start of census was then rescheduled for September 2020.

## Collection
### Methods

The PSA used various methods for the conduct of the 2020 census namely:
* Online census – with participants to be contacted through email and given access numbers
* Face-to-face interview by enumerators – with the dissemination of the survey either through pen and paper or computer tablets
* Scheduled phone interviews
* Self-filling of questionnaire to be collected by an enumerator
The conduct of the census through online means was limited due to many households in the country's rural areas has no access to internet infrastructure. The online census covered 2,000 households – mostly with members affiliated with the PSA and other government agencies.
All persons to be enumerated as members of a household or as residents of an institutional living quarter were those alive as of 12:01 a.m. of May 1, 2020
The 2020 census coincided with the rollout of the PhilSys national ID program but the PSA could not legally collect data from the national ID system for the census.

### Enumerators and supervisors

The PSA hired 140,000 people to serve as data enumerators and census supervisors for the 2020 census. Due to the COVID-19 pandemic, they were required to wear face masks and shields and observe social distancing when conducting the census as precaution against COVID-19. Prior to the postponement of the census due to the COVID-19 pandemic, the PSA planned to employ public school teachers for the conduct of the census. Such plans were abandoned after the opening of classes in public schools was postponed to October due to the pandemic.
