    • Estimated equivalent population using public supply water in the conterminous United States, CEM

    Metadata Updated: October 29, 2025

    The population using public supply drinking water was mapped in two ways: the census enhanced method (CEM) evenly distributes the population across the census block-group, and the urban land-use enhanced method (ULUEM) distributes the population only to certain urban land use designations in order to more precisely locate public supply users. This dataset consists of the total estimated population using public supply surface water and groundwater combined, distributed across block-groups.
