6. Philippine Statistics Authority (PSA)
• Is the government agency mandated to
conduct censuses and surveys to obtain
information about socio-demographic
characteristics of the resident of the
country.
• Census data are used by the government
to make plans. Censuses of population
and housing are conducted every 10
years on years ending in zero(e.g., 1990,
2000, 2010) to obtain population counts,
and demographic information about all
Filipinos.

7. • Through Republic Act 10625(also referred to
as The Philippine Statistical Act of 2013), PSA
was created from four former government
statistical agencies, namely: National
Statistics Office(NSO), National Statistical
Coordination Board(NSCB), Bureau of Labor
and Employment of Statistics(BLES) and
Bureau of Agricultural Statistics(BAS).
• The other agency created through RA 10625
is the Philippine Statistical Research and
Training Institute(PSRTI) which is mandated
as the research and training arm of the
Philippine Statistical System. PSRTI was
created from its forerunner the former
Statistical Research and Training
Center(SRTC).
