The 2019 Community Health Center Chartbook highlights important research and data on Health Center Program Grantees, as well as other Federally-Qualified Health Centers (FQHCs). In this document, unless otherwise noted, the term “health center” is generally used to refer to organizations that receive grants under the Health Center Program as authorized under section 330 of the Public Health Service Act, as amended (referred to as “grantees”). Data and research sources can be found at the bottom of each figure. Most slides draw from the Uniform Data System (UDS) maintained by the Bureau of Primary Health Care, HRSA, and DHHS. UDS data included in this chartbook are limited to health centers that meet the federal grant requirements and receive federal funding from the Bureau of Primary Health Care.
