WHEREAS, Batas Pambansa Blg. 72 provides for the taking of a national census of population by province, city, municipality and barangay;

WHEREAS, the NEDA had submitted the preliminary results of th 1980 population census of the Philippines by municipality, city and province as conducted by the National Census and Statistics Office (NCSO), which results were approved by the President under LOI 1083 for official use by all agencies and instrumentalities of the government in their planning and/or appraisal of development activities relating to population and other population-related matters;

WHEREAS, the population count at the barangay level could not as yet be finalized by the NCSO inasmuch as there is no complete official listing of barangays available as of this date and it appears that the NCSO list does not tally with the lists provide by the Ministry of Local Governments, the Commission on Elections and the Ministry of Finance;

2. Population counts of (a) barangays in existence in 1970 or 1972 which may not be found in either MLG or COMELEC lists, shall be included; and , (b) those barangays created (after the ratification of the Constitution in January 16, 1973) pursuant to Presidential Decree 86 or P.D. 86-A which concern mainly poblaciones, and in the case of Metro Manila, wards, shall be separately indicated and properly noted for formal creation in conformity with the Constitution.
