It is the second of six volumes documenting IFLS4. The first volume describes the basic survey design and implementation. The Indonesia Family Life Survey is a continuing longitudinal socioeconomic and health survey. It is based on a sample of households representing about 83% of the Indonesian population living in 13 of the nation’s 26 provinces in 1993. The survey collects data on individual respondents, their families, their households, the communities in which they live, and the health and education facilities they use. The first wave (IFLS1) was administered in 1993 to individuals living in 7,224 households. IFLS2 sought to re- interview the same respondents four years later. A follow-up survey (IFLS2+) was conducted in 1998 with 25% of the sample to measure the immediate impact of the economic and political crisis in Indonesia. The next wave, IFLS3, was fielded on the full sample in 2000 and IFLS4 was fielded in 2007 and 2008.. IFLS4 was a collaborative effort of RAND, the Center for Population and Policy Studies (CPPS) of the University of Gadjah Mada and Survey METRE. Funding for IFLS4 was provided by the National Institute on Aging (NIA). Grant 1R01 AG026676 and the National Institute for Child Health and Human Development (NICHD), grant 1R01 HD050764 and grants from the World Bank Indonesia office. The IFLS4 public-use file documentation, whose six volumes are listed below, will be of interest to policymakers concerned about socioeconomic and health trends in nations like Indonesia, to researchers who are considering using or are already using the IFLS data, and to those studying the design and conduct of large-scale panel household and community surveys. Updates regarding the IFLS database subsequent to publication of these volumes will appear at the IFLS Web site, http://www.rand.org/FLS/IFLS.
