The first Sinai Community Health Survey was conducted in 2002 with generous funding from the Robert Wood Johnson Foundation. It was the largest community-driven health survey ever to be conducted in Chicago and quickly became the primary source of meaningful, local-level health data for some of Chicago’s most vulnerable neighborhoods. The survey included a representative sample of 1700 adults and 800 children from 6 Chicago community areas: Humboldt Park, North Lawndale, Norwood Park, Roseland, South Lawndale, and West Town. Findings from the Sinai Survey helped identify the unique health needs of each of these communities and inform the development of public health interventions and policies.
