Data Source Summary and Regional Geography

The National Equity Atlas draws upon a regional equity indicators database assembled using a broad array of data sources and methodologies. Unless otherwise noted, all of the data presented on this website are based on analysis by PolicyLink and the USC Equity Research Institute (ERI). The database contains information for 301 geographies including the United States as a whole, all 50 states, the 150 largest metropolitan areas (based on 2010 population), and the 100 largest cities. Metropolitan areas are defined based on the U.S. Office of Management and Budget’s (OMB’s) December 2003 Core Based Statistical Area (CBSA) definitions while cities are defined to follow the designation of incorporated places used in the 2010 Census. The only the exception to this rule is the City and County of Honolulu, which is defined to include Honolulu County in its entirety to be consistent with the jurisdiction of the consolidated city-county government of Honolulu. Unless otherwise noted, data reported for all years have been assembled to follow these geographic definitions, and are thus geographically consistent over time.

The user should bear in mind that many of the analytical choices in generating the underlying regional equity indicators database were made with an eye toward replicating the analyses in multiple regions and the ability to update them over time. Thus, while more regionally specific and/or recent data may be available for some indicators, the data in the Atlas are drawn from our regional equity indicators database, which provides data that are comparable and replicable over time.

Details on the data sources and methods used for each indicator can be found by clicking on the links accompanying each indicator display (see the question mark). However, a few notes on dataset construction are relevant to many indicators so below we provide more detail on the methods used in developing the indicators, adjustments that were made to some of the underlying datasets, and clarification on some of the key terms that are used. For each section below describing analyses and adjustments performed to develop the indicators and underlying database, we include a list of the particular indicators for which they are relevant.
