India has one of the largest private healthcare sectors in the world with more than eighty percent ambulatory care and only twenty percent of ambulatory care is supported through the public healthcare sector (Gill S.S. and Ghuman R.S., 2003). Although 80 percent of India's population lives in rural areas only. 11 percent of doctors practice in these areas (Banerjee, Guha S., & Joshi S., 1985). Health problems in developing countries like India are largely a reflection of poverty. Three-quarters of the population live below the poverty line or at the subsistence level. This means that 70 to 90 percent of their income goes to food and related consumption. In such a context, social security support for health, education, housing, etc. becomes critical. A Primary Health Center is 'A center to provide as many services close to the people as possible and integrated curative and preventive health care to the rural community.' IPHS prescribed standards for a PHC covering 20,000 to 30, 000 population with one primary health center. Data was collected through the Census handbook of Solapur District and the Socio-Economic Review of Solapur District. The main objective of this research paper is to study temporal changes in the number of Primary Health Centres in Solapur district.
