The Indonesian Family Life Survey (IFLS) is an on-going longitudinal survey in Indonesia conducted by RAND and Survey METER. The IFLS is designed to provide data for studying behaviors and outcomes.  The survey contains a wealth of information collected at the individual and household levels, including multiple indicators of economic and non-economic well-being.

In addition to individual- and household-level information, IFLS provides detailed information from the communities in which IFLS households are located and from the facilities that serve residents of those communities.  These data cover aspects of the physical and social environment, infrastructure, employment opportunities, food prices, access to health and educational facilities, and the quality and prices of services available at those facilities
