The National Statistics Office (NSO) was first called Bureau
of the Census and Statistics (BCS) when Commonwealth Act (C.A.)
No. 591 was approved on August 19, 1940.
Executive Order No. 314 transferred to the BCS the powers, functions, duties, personnel, appropriations,
property and records of other statistical agencies effective January 1, 1941.
Among these were the functions of the Division of Labor Statistics of the Department of Labor and
of the Section of Vital Statistics of the Bureau of Health, Department of Instruction.

- Division of Statistics of the Department of Agriculture and Commerce;

Presidential Decree No. 418 issued on March 20, 1974 reconstituted the BCS into a new agency known
as the National Census and Statistics Office (NCSO) under the administrative
supervision of the National Economic and Development Authority (NEDA).
In 1987, by virtue of Executive Order No. 121 entitled "Reorganizing
and Strengthening the Philippine Statistical System and for Other Purposes,"

the Office of the President.
