This map was created with ArcGIS Online. Interactive maps are easy to make and can be shared or embedded in websites. The Demographics and Lifestyle group provides ready-made datasets you can use to make easy interactive maps. See the ArcGIS Online documentation to get started.
For more information see our guide:
Social Explorer is the easiest tool to use but other tools may be more appropriate in certain circumstances.
American FactFinder has only the most recent years of its surveys; Social Explorer has all.
American FactFinder has all available geographies (except block groups for ACS data); block groups are available in Social Explorer and DataFerrett*
American FactFinder has all available variables; Social Explorer doesn’t have variables that involve some suppression.
Only DataFerrett* allows you to create your own.
Social Explorer and American FactFinder both have this capability; American FactFinder is harder but has some variables (from current surveys!) that Social Explorer does not.
Have to use public use microdata sample (PUMS) through DataFerrett* (only available geographies are public use microdata areas [PUMAs], super-PUMAs or higher levels of geography, e.g., states), or apply to use un-anonymized microdata through the Triangle Census Research Data Center* (which is a long-term process—six months or more).
American FactFinder has most of the (current) Bureau surveys; Social Explorer has all of the decennial population surveys, 1790 to present; DataFerrett* has the Current Population Survey and a few other more “rare” surveys (SIPP, SAIPE, et al.), plus non-Bureau data like the Home Mortgage Disclosure Act data; the National Survey of Fishing, Hunting and Wildlife-Associated Recreation; and much more.
*If you need to use DataFerrett or the Triangle Census Research Data Center, or need to map something in American FactFinder, contact the Data Services Librarian.
