Monthly and Annual population and water withdrawal maps of Rhode Island 2014-2021

This data release consists of multi-band 30-meter x 30-meter pixel rasters of estimated population and domestic self-supplied water withdrawals in Rhode Island between July 2014 and June 2021. Population raster data were generated using a national data product of 2010 population spatially distributed across land cover data and U.S. Census Bureau data of population growth estimates to adjust populations for each year 2014-2021. Estimates for changes in population between winter and summer months are also included to generate seasonal population estimates. The coefficients used to describe these variations in populations for each U.S. Census Bureau block group in Rhode Island are included in this data release. Estimated water withdrawal rasters were generated using an estimated population for each pixel and domestic per capita water use rates calculated from public-supply data. Spatial boundaries of public supplies in Rhode Island were used to classify areas of domestic water use outside of those served by public suppliers as self-supplied. Three comma-separated values (CSV) files contain the coefficients used to develop the final products. The three multi-band raster (tagged image format [TIF]) files contain the spatial representation of the estimated populations and self-supplied domestic water withdrawals in Rhode Island.
