Local agencies and leaders work hard to meet the service needs of low-income Hispanic populations in their communities. Having up-to-date, high-quality information on the local Hispanic population—and the diversity within this population—is critical. In this guide, we describe how agencies can use the U.S. Census Bureau’s American FactFinder tool to get data from the American Community Survey (ACS) for their local area. We also demonstrate how to generate results answering these questions for multiple time periods, how to export American FactFinder results into user-friendly tables, and how to interpret some basic results.
