The Population and Community Development Association (PDA) was founded in 1974 as a non-governmental organization with the initial aim to complement the efforts of the Royal Thai Government in promoting family planning in Thailand, especially in areas where knowledge and access to services were scarce. Utilizing a participatory, community-based approach, PDA recruited and trained residents of villages and urban neighborhoods to provide information on family planning, including the supervised, non-medical distribution of oral contraceptives. This distribution network covered more than one-third of the country, thus contributing significantly to the decrease in the annual population growth rate from 3.3% in the mid-1970s to 0.6% in 2005. During the same period, the number of children per family fell from 7 to under two.
