Additional Data Search Tips

If you can't find the data that you're looking for on this page, try using these tips to search for more.

Open a browser of your choice:

  • Start by using locations to narrow your search, for example use "Country Name," "State Name," or "County Name" to find data that is more granular.
  • Use the term "Open Data" rather than "free data" to help ensure your results are more reliable. Open data is a term used by governments, agencies, and other organizations that want to make data more transparent.
  • Be sure to access sources that are produced by reputable organizations-- look for data that is produced by governments or national, state, or country agencies. 
  • Never download data from an insecure site. Be sure that sites feature a green or black lock symbol in front of the URL.

General/Unsorted Datasets

Government Data (Federal, State, Local, etc.)

Academic Data

Data Repository Lists & Registries

A great place to start if looking for subject-specific data. Provides links to open data repositories sorted by subject area.

General Data Repositories

Large open data repositories that contain data from all subject disciplines. Both more heavily used than the subject-specific repositories and may provide results.
