Find your UHF neighborhood
Environmental health data can come at several different geographies, or neighborhood boundary schemes. Often, health data are available at a neighborhood boundary scheme called UHF42, which breaks up NYC into 42 neighborhoods (read more about UHF42 geographies).
Sometimes, you may be looking for data for a Community District or a City Council District, but the data are only available by UHF42 neighborhood. Click on the Community District or a City Council District below to identify the overlapping UHFs, and get links to our Neighborhood Reports with data by UHF42 neighborhood.
About the data
Data used include the 2023 American Community Survey, and 2025 City Council Districts shapefile. Get more geography resources, including shapefiles, topojsons, and geojsons, from our Github repository.
