Census Roundup: Links to data, maps, analysis, and more about the 2010 Census

NB: This page will be updated later in 2011 with links to Summary File 1 resources (i.e., the full data release from the 2010 Census).

On March 24, 2011, the Census Bureau completed its state-by-state publication of official population counts from the 2010 decennial census. Data for New York State was included in this last release of states.

For now, the data includes a subset of the complete information collected in 2010 in what is commonly known as the "PL-94-171" file or the "Public Law" file. This refers to the federal statute that requires the Bureau to provide states with the data essential for the redistricting process. The data released last week includes population counts by major race/ethnicity categories, by age under 18 and 18 and older, and housing counts (occupied or vacant). More detailed information on age, gender, and race/ethnicity sub-groups will be published in summer 2011.

Many government agencies, media outlets, academic institutions, and others have begun to look closely at the data and have posted links to their information. In an effort to try to collect these online resources in one place, we provide the links below, grouped by region and category. (News articles are excluded from the list; the links focus on data tables, maps, and analysis.)

Please let us know if we should add other links!

Nationwide resources & analysis

  • CUNY's Center for Urban Research provides interactive maps of 15 urban regions showing block-by-block race & ethnicity change from 2000 to 2010. (Related maps and resources here.) Several blogs have highlighted our maps, such as:
    • a Huffington Post article titled "The Changing Face of America" by George Mason University professor Michael McDonald, who has also pioneered an open source online redistricting application. Dr. McDonald concluded by saying that people accessing our maps will be "fascinated -- and perhaps surprised -- at how your favorite urban area is changing."
    • the MacArthur Foundation's Building Resilient Regions blog wrote that CUNY's "maps are sure to be useful for social service agencies, government officials, real estate professionals, and urban designers, among others who are interested in how cities move and change–not to mention the residents who live in them and contribute to the fabric of the city." A follow up post described the maps as "amazing work", noting that "It's hard not to spend hours on these maps, zooming in to certain neighborhoods or back out to the big-picture shifts."
    • the Texas Tribune highlighted how our maps visualized demographic change in Houston.
    • a Denver-based mapping consultant implemented a version of our mapping technique in Colorado.
  • Census Bureau's Redistricting Data website.
  • US2010 (a program of research on recent changes in American society led by Professor John Logan, supported by the Russell Sage Foundation and Brown University).
  • Social Explorer (interactive maps of current and historical census data led by CUNY Professor Andy Beveridge).
  • (interactive site for investigating U.S. demographic trends, provided by the Social Science Data Analysis Network (SSDAN) at the University of Michigan, led by Professor Bill Frey; emphasizes graphics, maps, exportable trend data, and segregation analysis for each state).
  • the Missouri Census Data Center repository of 2010 Census data and analysis.
  • All Things Census (blog about census methods, findings and resources by the Pew Research Center).
  • Analysis of metropolitan segregation across the US (posted at the online news site Salon).
  • Census resources for journalists (but also useful for others!) from the Investigative Reporters and Editors (IRE) group.
  • USA Today Census API (application programming interface) that lets you programmatically access census data (available geographic levels: nation, state, county, city/town).
