The Urban Health Initiative (UHI) is a decade-long, $65 million national program of The Robert Wood Johnson Foundation (RWJF) to improve the health and safety of children in five cities: Baltimore, Detroit, Oakland, Philadelphia, and Richmond. The Foundation established UHI in 1995 — partly in response to the 1992 Los Angeles riots — to determine whether a concerted, collaborative effort could bring about citywide improvements in multiple measures of child well being.
