In the absence of comprehensive registration of population and vital statistics, demographic surveys are the primary source of data used in monitoring the progress and evaluating the impact of the population program of the country. The Philippine Population Program was officially launched in 1970. Since then, it has undergone many changes in its policy and program directions. In the beginning, the program was centered on fertility reduction and contraceptive distribution, using a clinic-based approach. In the 1970s, the family planning program shifted to a family welfare approach, adopting a combined clinic and community-based delivery approach. In the 1980s, the population policy was restated, calling for the broadening of population concerns beyond fertility reduction to cover family formation, the status of women, maternal and child health, morbidity and mortality, population distribution and urbanization, internal and international migration, and population structure (Commission on Population, 1997: 1)
