ICLUS Data for the Northwest Region (V.1)
ICLUS data made available to the Regional groups of the National Climate Assessment consists of population and housing density. Population data are based on the 2000 U.S. Census and use fertility rates from the Census Bureau to project population to 2100 in 5-year time steps for each county in the conterminous United States. By using high and low fertility rates, scenarios are consistent with A2 and B1 scenarios, respectively. The population data are used as inputs to a spatial allocation model, which produces maps of housing density. These data are classified into four categories of urban, suburban, exurban, and rural. The resolution of these data is 1 hectare.
Datasets available here cover the Northwest region. All data are compatible with standard Geographic Information Systems (GIS).
|Dataset to download||Description||Metadata|
