The first census of the Philippines during the period of American occupation was taken on March 2,1903. About sixteen years later, the second census was taken. The need for a new census became apparent as the Philippines entered the Commonwealth period and approached final independence. The National Assembly passed a bill providing for the taking of a census which was approved and became Commonwealth Act No. 170, on November 12, 1936. President Quezon requested the services of an expert on census matters from the United States Government on August 17, 1937. The services of Mr. Ray Hurley, Acting Chief Statistician of Territorial, Insular, and Foreign Statistics of the United States Bureau, of the Census, were secured and upon his arrival in Manila he was appointed Expert on Census Matters effective as of October 9, 1937.
