Data Hero


CMAP’s many data-driven projects provide partners with vetted and trustworthy information. Our data projects are often the result of years of research and collaboration with federal, state, and local sources.

Community Data SnapshotsThese summarize demographics, housing, employment, transportation habits, retail sales, and land use in northeastern Illinois' seven counties, 284 municipalities, and 77 Chicago neighborhoods.

Regional Indicators. ON TO 2050 includes a set of regional indicators that serve as benchmarks for monitoring progress of plan implementation. CMAP also tracks additional indicators that provide insight into the state of the region's economy and transportation infrastructure.

Land Use DataUpdated every five years, CMAP's Land Use Inventory supports regional planning and policy evaluations as well as local technical assistance activities. CMAP has also established a procedure for evaluating potential Developments of Regional Importance. A partnership with Chicago Wilderness enhances information on "green infrastructure" — the region's core conservation lands.

Transportation DataCMAP prepares future traffic projections, which are supported by a substantial regional travel demand modeling system and a large-scale travel survey, as well as an upcoming commercial vehicle survey. The agency also monitors, analyzes, and provides information on transportation system performance.

Community Cohorts. CMAP determines the level of local capacity and technical assistance needed for communities in the region by using the Community Cohort Evaluation Tool (CCET). This tool assigns Community Cohorts throughout the CMAP region based on four factors: population, income, tax base per capita, and percent of population located in an economically disconnected or disinvested area (EDA). The Community Cohorts will be assigned on an annual basis every April using this tool and the most current data available. Please click here for the Fiscal Year 2021 list of Community Cohorts.
