Population Growth: LandCast
Patterns of human population density and how these patterns change over time with population growth impact almost every aspect of ecosystem service sustainability. These patterns influence both the capacities of ecosystems to produce resources and the demand for those resources from rural and urban populations. Models of future population patterns, then, can inform strategies for adapting to expected changes.
Developed by the Oak Ridge National Laboratory (ORNL), the LandCast 2030 and 2050 High-Resolution Population Projections model 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.
Current population density and factors related in predictable ways to population density (such as land cover, slope, road proximity, distances to larger cities, and additional data) were included in model development, along with a projection methodology modified from the U.S. Census. Future projections using the models are potentially useful in planning efforts to minimize impacts on areas facing population growth or decline, in addition to other research and education uses.
