United Hospital Fund Areas is a polygon theme representing United Hospital Fund (UHF) areas in New York City. These are aggregated boundaries based off of the ZIP_Code_Areas_w_UHF_DOHMH_2006.shp file. NOTE: If comparing to older, UHF / ZIP level analysis, areas may not match exactly due to ZIP code shifts over time. The ZIP codes in this file were revised off of NYC DCP 2004 LION street centerline data, UHF / ZIP code match comparison information was compiled by DOHMH in 2006. Deviations in boundaries as compared to other, existing datasets are due to these factors and should be considered accordingly. This data should be treated as work in progress, DRAFT condition.
