Dementia DataHub: Alzheimer’s Disease & Related Dementias

Map
An interactive map shows the prevalence of dementia at the state level across the United States. The map was filtered to show the prevalence for highly likely dementia diagnoses across both Medicare Advantage and Medicare fee-for-service programs for all age groups, races/ethnicities, and genders related to the total population. A popup window shows that in Minnesota, the prevalence of dementia by these filters is 6.2 percent across a population of 5670.5 thousand. The correlation coefficient is 0.53.

The Dementia DataHub website is a first-of-its-kind surveillance system for Alzheimer’s Disease and related dementias (ADRD) across the United States.

As the nation’s population ages, the need to track Alzheimer’s Disease and related dementias (ADRD) has never been greater.

NORC’s new Dementia DataHub reports geographic counts of diagnosed ADRD prevalence, incidence, payments, mortality, and COVID-19 infection from the county level on up. Built in collaboration with George Washington University’s Milken Institute School of Public Health and KPMG LLP., with support from the National Institute on Aging, our hub draws data from administrative health care data systems, including Medicare fee-for-service claims and Medicare Advantage encounter data.

We engaged experts in data visualization and privacy, geographic information systems, communications, and web design from across NORC. Our expanded team developed a visually appealing site that summarizes research and offers easy-to-use interactive dashboards and maps of results at the national, state, and county levels, as well as public use files.
