The California Health Interview Survey (CHIS) is the nation’s largest population-based state health survey, and the first in California to interview people from every county. CHIS is conducted on a continuous basis, allowing it to provide a detailed picture of the health and health care needs of California’s large and diverse population. A full data cycle takes two years to complete, with over 50,000 Californians surveyed. CHIS interviews Californians in several languages: English, Spanish, Cantonese, Mandarin, Korean, Vietnamese and Tagalog.
The Guatemalan Survey of Family Health was designed to examine the way in which rural Guatemalan families and individuals cope with childhood illness and pregnancy, and the role of ethnicity, poverty, social support, and health beliefs in this process. It is part of a larger study designed and carried out by Noreen Goldman (Princeton University) and Anne Pebley (FSPH/RAND), in collaboration with the Nutritional Institute of Central America and Panama (INCAP) in Guatemala, with funding from the National Institute of Child Health and Human Development.
The Multicenter AIDS Cohort Study (MACS) is the first and largest study dedicated to examining the natural history of AIDS.

The Los Angeles Family and Neighborhood Survey (L.A. FANS) is a study of adults, teens, children, and neighborhoods in Los Angeles County. The study follows children and families over time, with the goal of understanding how neighborhoods affect a variety of outcomes, including children’s development and well-being and stress and health among children and adults. In 2000-2001, L.A. FANS interviewed 3,000 families in 65 neighborhoods as part of Wave 1 of L.A.FANS. For Wave 2, which was fielded in 2006-2008, L.A. FANS re-interviewed these families as well as new families who moved into these neighborhoods. L.A.FANS is conducted by the RAND Corporation, a non-profit research organization in Santa Monica, in collaboration with the Fielding School of Public Health.
