Since being created in 1983, the Community Health Data Base (CHDB) has served the information needs of hundreds of organizations in Southeastern Pennsylvania (SEPA) by providing up-to-date and reliable community-level health and social service data. CHDB's central component, the Southeastern Pennsylvania Household Health Survey, is one of the largest local health surveys in the country. This biennial health survey collects information on more than 13,000 residents (children, adults and seniors) living in the five-county SEPA region. The survey provides data on a broad range of health topics including health status, access to and use of health care, personal health behaviors, health screening, health insurance status, women's health, children's health, and older adult health and social support needs. Over 350 local and regional organizations use these data to plan, market and access health services for underserved populations — particularly those at-risk for fair or poor health due to age, race, gender, insurance status, or poverty.
