The Dallas County Community Health Needs Assessment (CHNA) was designed to ensure that the Dallas County public health system continues to effectively and efficiently serve the 2.4 million residents of the county. Dallas County Health and Human Services (DCHHS) is one of seven local health departments in the nation participating in the Centers for Disease Control and Prevention (CDC) National Public Health Improvement Initiative. In support of that initiative, DCHHS designed and led this CHNA in collaboration with the Parkland Community Health Institute to determine the top health issues facing Dallas County residents and recommendations for improvement. A public health improvement workgroup comprised of healthcare executives, leaders of civic organizations, schools, health departments, and representatives of local universities, provided development and implementation guidance. The CHNA uses detailed public health outcome secondary data at the county and community level to identify health assets, gaps, disparities and trends. This data was supported with primary data from two focus groups and eight key informant interviews. The document provides statistical data and graphics, as well as a directory of various kinds of health facilities.
