Population Forecast

Population Forecast

The Chicago Metropolitan Agency for Planning 2050 Forecast of Population, Households and Employment was developed in support of the ON TO 2050 comprehensive regional plan adopted in October 2018.

The primary function of these data is to serve as an input for CMAP transportation modeling activities, which are an important component in air quality conformity evaluations of the region's Transportation Improvement Program (TIP).

2050 Projections by Local Allocation Zone GIS shapefile representing small-area CMAP forecasts of population, households and employment, with base-year (2015) estimates and projections at five-year intervals to the year 2050. Local Allocation Zone (LAZ) areas represent subzones used in CMAP’s travel demand model, subdivided by municipal (2010) boundaries and Chicago Community Areas for more refined analyses. These projections are the result of modeling procedures which incorporate a number of factors represented at a variety of scales; as such, they cannot be considered precise at any specific location. These data are only appropriate for planning purposes when aggregated to larger areas.
