Retiring American FactFinder: Final Reminder The U.S. Census Bureau has retired American FactFinder (AFF), its statistics and information search engine after 20 years. AFF will remain as an archive system for data and functionality that are not yet available in data.census.gov until March 30, 2020.   After March 30, 2020, our American FactFinder will be decommissioned and no longer available. Get Ready How to Transition to data.census.gov Data.census.gov is the new platform to access data from the U.S. Census Bureau. The vision for data.census.gov is to improve the customer experience by making data available from one centralized place so that data users spend less time searching for data content and more time using it. Data previously released on AFF are now being released on the U.S. Census Bureau's new dissemination platform.
