Community health centers (CHCs) are the cornerstone of primary care for 29 million people, most of whom are low-income, underserved, and live in rural populations. Until 2016, CHCs reported community health workers (CHWs) as part of their overall enabling services workforce, making it difficult to report CHW use in the annual Uniform Data System (UDS).

This article examines changes in the community health worker (CHW) workforce among CHCs from 2016 to 2018 and factors associated with the use of CHWs.
