The National Association and County & City Health Officials (NACCHO) published their “2019 National Profile of Local Health Departments.” The purpose of the study is to develop a comprehensive and accurate description of local health department infrastructure and practice. The data are used to inform public health policy at the local, state, and federal levels and can support projects to improve local public health practice. Data are also used in universities to educate the future public health workforce about local health departments and by researchers to address questions about public health practice.
