These projections are therefore consistent with the demographic assumptions of the SSP2 and SSP5 socioeconomic scenarios. ICLUS population projections are used as inputs to a land use model, which spatially allocates five residential land uses (exurban-low, exurban-high, suburban, urban-low, urban-high) as well as commercial and industrial.<div><br /></div><div>Learn more about the recent <a href='http://cfpub.epa.gov/ncea/global/recordisplay.cfm?deid=306651' style='box-sizing: border-box; transition: background-color 0.25s linear, border-color 0.25s linear, box-shadow 0.25s linear, color 0.25s linear, opacity 0.25s linear, text-shadow 0.25s linear, transform 0.25s linear; outline-offset: 2px; -webkit-tap-highlight-color: rgba(0, 0, 0, 0);'>Updates to the Demographic and Spatial Allocation Models to Produce Integrated Climate and Land Use Scenarios (ICLUS) (Version 2.0)</a></div>EPAICLUSSSPClimate ChangeEPA’s Integrated Climate and Land-Use Scenarios (ICLUS) project explores future changes in human population, housing density, and impervious surface for the United States. These projections are broadly consistent with peer-reviewed storylines of population growth and economic development that are now widely used by the climate change impacts community.
