This guide will help you find the best databases, search tools, and other resources for finding statistics and other datasets related to various topics. 

Questions to Ask Yourself

The following questions will determine where you need to look and whether the data is available:

  • What level of observation/analysis do you need? (e.g. individuals, communities, states, countries...)
  • What time period? (most recent? 5 years? historical time series?..)
  • What frequency? (annual, quarterly, monthly, ...)

Tips for Finding Statistics

  • Think of which organizations are likely to produce the data and check the web sites of those sources.
