Attributes for NHDPlus Version 2.1 Catchments and Modified Routing of Upstream Watersheds for the Conterminous United States: Population Density from U.S. Block-Level Population Density Rasters for 2010

This tabular data set represents population density, persons per square kilometer from 2010 Census block level data, processed by James Falcone (USGS, 2016), compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data for population density was produced by the U.S. Geological Survey (Falcone, 2016). Units are persons per square kilometer. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through...

Attributes for NHDPlus Version 2.1 Catchments and Modified Routing of Upstream Watersheds for the Conterminous United States: Housing Density 1940-2010

This tabular data set contains information on historic housing densities for every 10 years from 1940-2010, compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is from Hammer and others (SILVIS Lab, University of Wisconsin, 2008). The data provided here contains information for eight time periods: 1940, 1950, 1960, 1970, 1980, 1990, 2000, and 2010. The units are housing units per square kilometer. Reach catchment information characterizes...
