The update of this information—based on more recent, Census Bureau 2016-2020 American Community Survey (ACS) 5-year estimates data and 2020 Decennial Census data—is part of a larger effort to ensure that the data used to determine the eligibility for CDFI Certification and CDFI Fund programs is current and reflective of current socioeconomic and demographic information. This announcement provides additional updates regarding the documents and specific CDFI Fund programs described below.
