County Level Data - Updated January 2024
Here in South Carolina, we are fortunate to have the nation’s most comprehensive statewide registry of residents diagnosed with Alzheimer’s disease and related dementias.
In partnership with the SC Alzheimer's Disease Registry, the Alzheimer's Association SC Chapter has produced county fact sheets to shed light on the impact of dementia on our local communities.
The new 2024 fact sheets below reflect data from 2021, the most current year that complete data is available through the Registry.
At that time, 122,699 South Carolinians were living with a diagnosis of Alzheimer's disease or related dementias (ADRD). Statewide, African Americans were an average of 35% more likely to have ADRD than their non-Hispanic white counterparts.
Each county fact sheet offers a breakdown of cases by age, race, place of residence and county heat map, as well as growth in cases since the year 2000.

The SC Alzheimer's Disease Registry is maintained by the Arnold School of Public Health at the University of South Carolina, with support from the SC Department of Health and Human Services and the SC Revenue and Fiscal Affairs Office.

The data on this page represents diagnosed prevalence of all dementias in South Carolina based on records available to the SC Alzheimer's Disease Registry. Individuals who have mild forms of the disease, but lack a diagnosis, do not appear in the Registry data. In fact, research suggests that the number of individuals with ADRD may be nearly 50% greater than the number with diagnosed ADRD.
While diagnosed prevalence data is not available for every state, the Alzheimer's Association offers information on the impact of Alzheimer's and caregiving in any state nationwide, including estimated prevalence at the state and county level. Learn more.
