Methodology and Data Sources for CMAP's Regional Snapshot

The CMAP Regional Snapshot is meant to depict where the region stands in measurable terms, regarding fundamental issues that will shape our communities in years to come.  Numerous partners across the region have done much good work to quantify the status and needs of metropolitan Chicago; CMAP’s role is to coordinate and enhance activities across those areas while promoting regional priorities.  The Regional Snapshot is not intended as an all-encompassing overview of northeastern Illinois. It is instead a short encapsulation of selected data points and trends that shed light on issues that have been identified as priorities in the region.  Click here to download the Regional Snapshot (9MB PDF).

Regional Snapshot Methodology and Sources

For consistency when comparing the Chicago region with its U.S. peers, we have selected Dallas, Los Angeles, New York, and Philadelphia, which make up the top five cities in terms of population.  Unless noted, data refer to metropolitan Chicago as a whole, and to the other cities’ broader metropolitan areas, too.  U.S. metropolitan regions are defined by Core Based Statistical Areas (CBSAs), Consolidated Metropolitan Statistical Areas (CMSAs), or Metropolitan Statistical Areas (MSAs), depending on data availability. 

CBSAs, CMSAs, and MSAs are large metropolitan regions that include one or more primary urban centers, as defined by the federal Office of Management and Budget (OMB) for use by federal statistical agencies.  The Chicago CBSA includes the Chicago, Naperville, Joliet metro area, as well as the metro areas surrounding Gary, Indiana and Kenosha County, Wisconsin..  Detailed descriptions of each type of metro region begin on page 9 of this document. For international comparisons, the selected peer group includes Berlin, London, Paris, and Tokyo and data are reported by metropolitan regions referred to as agglomerations.

Note: The Census Bureau 2005 population estimate for CMAP’s 7-county region is 8.4 million.  This figure includes population estimates by CBSA geography, which, for Chicago, is larger than the CMAP region.

Agglomerations include a central city and neighboring communities linked to it (e.g.) by continuous built-up areas or commuters. Some agglomerations have more than one central city (e.g. "The Ruhr"). Official censuses and estimations are mostly the basis of the presented figures; the definitions of agglomerations are sometimes based on unofficial or own estimates. The population figures of the agglomerations and cities are computed for following date: 2006-11-22. The figures of such a statistic are all of varying, and some of suspect accuracy. There are several reasons: the varying relevance and accuracy of sources, the poor comparability of definitions of agglomerations, errors in the projections and so on. Nevertheless, the population figures presented on this page are more relevant and more comparable than most of the data presented elsewhere.

Note: Prior to Census 2000, the questionnaire permitted respondents to mark no more than two digits for their travel time, limiting reported travel time to 99 minutes.  Three digits were made available in the Census 2000 questionnaire, reflecting the greater frequency of extremely long commutes.  As a result, it is estimated that about 1 minute of the 3.1 minute increase for the Nation between 1990 and 2000 was due to this change in methodology (Source: U.S. Census Bureau, Journey to Work 2000. Census 2000 Brief.  U.S. Department of Commerce, Economics and Statistics Administration, U.S. Census Bureau.  March 2004).
