2010 Census Data Collection and Navigation

The 2010 Census is part of the Decennial Census program mandated by the US Constitution.

The 2010 Census had only 10 questions.  They covered these topics:

  • Race
  • Ethnicity
  • Sex
  • Age
  • Household Relationship
  • Housing Tenure (own or rent)

Make Maps with Social Explorer

For ACS data, to access Margins of Error (MOE) in Social Explorer, make sure you are using the Census Bureau's tables. Social Explorer defaults to using their tables, which are cleaned up, easier to use versions of census data. These are appropriate for some uses, but researchers needing more authoritative data and especially those needing Margins of Error will have to switch to the ACS tables, in the tables portion of the process of selecting data in "Reports"
