New rankings show healthiest and least healthy counties in South Carolina

March 29, 2023

Beaufort County ranks the healthiest in South Carolina and Allendale is the least healthy county in the state, according to new County Health Rankings data from the University of Wisconsin Population Health Institute (UWPHI). The South Carolina Institute of Medicine and Public Health (IMPH) serves as the lead dissemination agent in South Carolina for the annual County Health Rankings. The Rankings are available at

For more than a decade, County Health Rankings’ data, evidence, guidance and stories have broadened the nation’s understanding about the multiple factors that shape health. This year’s findings show that counties with well-resourced civic infrastructure have higher rates of high school completion, higher household incomes, less income inequality and lower rates of children in poverty and uninsured adults. In these communities, people also tend to live longer.

“Our findings reveal that people and places thrive when all residents have the chance to participate in their communities,” said Sheri Johnson, principal investigator of County Health Rankings & Roadmaps and director of the University of Wisconsin Population Health Institute. “History shows that we can remake systems and structures through civic participation that are beneficial to all.”

This year’s County Health Rankings looked at a series of factors to measure civic infrastructure and participation in counties including access to parks, school funding adequacy, broadband, voter turnout and self-reported census participation.

“Social connection is a health determinant that is not discussed enough, but research shows that being engaged in the community tends to lead to longer and healthier lives,” said Maya Pack, executive director of the South Carolina Institute of Medicine and Public Health. “This is why IMPH is currently convening a taskforce of stakeholders and experts from across South Carolina to identify recommendations — such as supporting the GetConnectedSC initiative — to reduce social isolation in older adults.”

Improving Civic Health Requires Action

The Rankings offer several solutions to build civic health, including investing in libraries, community centers and other public spaces to encourage in-person connections; expanding civic knowledge and skills through youth leadership programs and implementing voter registration and turnout initiatives to expand representation in the democratic process.

In addition to these solutions, the program’s What Works for Health offers more than 400 evidence- informed strategies to help communities on their health improvement journey. Each strategy is rated for its effectiveness and likely impact on health disparities. Additionally, the Rankings website has improved features to make it more accessible. Data are now easier to find, use and understand with detailed descriptions that offer helpful context about counties with information such as links to identify the Indigenous nations native to the land.
