ICLUS v2.1 land use projections for the Fourth National Climate Assessment (SSP2)

Published by U.S. Environmental Protection Agency, Office of Research and Development-National Center for Environmental Assessment | U.S. Environmental Protection Agency | Metadata Last Checked: January 27, 2026 | Last Modified: 2018-02-28T00:00:00.000+00:00
SSP2 is a “middle-of-the-road” projection, where social, economic and technological trends do not shift markedly from historical patterns, resulting in a U.S. population of 455 million people by 2100. Domestic migration trends remain consistent with the recent past. This version of the ICLUS model does not include climate change projections to dynamically update location-specific amenities when calculating migration. These projections will include the “nocc” label in the file name to indicate this difference.
