Collado Deputy Administrator Socorro D. Abejo Director III, Household Statistics Department ISSN 0117-1453 FOREWORD The 2010 Census of Population and Housing (2010 CPH) Report No. 1 is one of several publications designed to disseminate the results of the 2010 CPH. This report presents the population by province, city or municipality and barangay based on the 2010 CPH. This information will be useful for the formulation of the social and economic development policies, plans and programs of the Government. These are also important for purposes of the calculation of Internal Revenue Allocation, determination of number of congressional districts, and creation or conversion of various administrative geographic units. The 2010 CPH is the 13th census of population and the 6th census of housing that was conducted in the country since the first census undertaken in 1903. It was designed to take an inventory of the total population and housing units in the country and collect information about their characteristics as of the reference period May 1, 2010. The 2010 CPH data were gathered through house-to-house visit and interview of a responsible member of every household visited. The data processing of the results of the 2010 CPH utilized a combination of Optical Mark Reader (OMR) technology and data encoding. The 2010 CPH results on population counts underwent careful evaluation for reasonableness and consistency with expected demographic patterns and trends in accordance with evaluation procedures of international standards. Unusual changes and deviations of 2010 CPH population counts and related indicators from expected patterns and trends were field-verified. The successful completion of the 2010 CPH would not have been possible without the unwavering support and services rendered by the local and national officials, government and private agencies, media, and non-government organizations. We acknowledge with gratitude the census coordinating boards at the national, regional, provincial, city, and municipal levels in ensuring agency logistic support and assistance, the dedication of teachers from the Department of Education, the hired census personnel, and our very own NSO personnel who acted as census enumerators and supervisors, and the cooperation of the general populace. The NSO extends its deep appreciation of their support to this important undertaking. CARMELITA N.
