WaSSI (Water Supply Stress Index) predicts how climate, land cover, and human population change may impact water availability and carbon sequestration at the watershed level (about the size of a county) across the lower 48 United States. WaSSI users can select and adjust temperature, precipitation, land cover, and water use factors to simulate change scenarios for any timeframe from 1961 through the year 2100. Simulation results are available as downloadable maps, graphs, and data files that users can apply to their unique information and project needs. WaSSI generates useful information for natural resource planners and managers who must make informed decisions about water supplies and related ecosystem services...

The American Community Survey (ACS) is a national, publicly available survey provided by the U.S. Census Bureau that collects information about population, education, housing, economic status, and more. Planners, public officials, entrepreneurs, and researchers rely on the data collected through this survey to help understand community conditions and to support community planning efforts.Seasonal homes are abundant in the Appalachians, and are particularly prominent among the more rural areas that provide access to the region’s cultural and natural amenities and scenic views. These factors, coupled with an ideal mountain climate compared to surrounding areas, have brought national attention and have made much of...

Using GIS, the SILVIS Lab at the University of Wisconsin-Madison calculated housing and population counts at the block group level with data from the decennial U.S. Census to produce a spatially explicit dataset for the conterminous U.S. This data can help to understand where on the landscape the most and the least dense populations of people live. Housing density can be used as an indicator of urbanization and land-use intensification.

The Urban Influence measure developed by the U.S. Department of Agriculture (USDA) Economic Research Service (ERS) identifies metropolitan counties by population size and outlines where natural area and urban boundaries exist. This can help to indicate where increased stresses on ecosystem services may occur.The boundaries between urban, rural, and natural areas in Appalachia are increasingly defined by the accelerated demand for ecosystem services from growing urban populations. Increases in “urbanness” not only stress the capacity of affected landscapes to provide ecosystem services, but also magnify the pressure on nearby natural areas to provide those services to more people. However, opportunities exist for...

Developed by the Oak Ridge National Laboratory (ORNL), the LandCast 2050 High-Resolution Population Projection models future national-level human population densities. The models estimate the probability of a population being at a particular location, which measures where people will likely be in the future, not necessarily their places of residence.The LandCast 2050 data set is an empirically-informed spatial distribution of projected population of the contiguous U.S. for 2050 compiled on a 30” x 30” latitude/longitude grid. Population projections of county level numbers were developed using a modified version of the U.S. Census’ projection methodology-with the U.S. Census’ official projection as the benchmark....
