Prevalence of Alzheimer's disease dementia in the 50 US states and 3142 counties: A population estimate using the 2020 bridged‐race postcensal from the National Center for Health Statistics
Open accessAbstract
INTRODUCTION: This study estimates the prevalence and number of people living with Alzheimer's disease (AD) dementia in 50 US states and 3142 counties. METHODS: We used cognitive data from the Chicago Health and Aging Project, a population‐based study, and combined it with the National Center for Health Statistics 2020 bridged‐race population estimates to determine the prevalence of AD in adults ≥65 years. RESULTS: A higher prevalence of AD was estimated in the east and southeastern regions of the United States, with the highest in Maryland (12.9%), New York (12.7%), and Mississippi (12.5%). US states with the highest number of people with AD were California, Florida, and Texas. Among larger counties, those with the highest prevalence of AD were Miami‐Dade County in Florida, Baltimore city in Maryland, and Bronx County in New York. DISCUSSION: The state‐ and county‐specific estimates could help public health officials develop region‐specific strategies for caring for people with AD.

States and counties in the eastern and southeastern U.S. have the highest prevalence of Alzheimer's dementia; eight of the 10 counties (with at least 10,000 older adults) with the highest prevalence are in the East and Southeast.
“As shown in Figure 3, states and counties in the eastern and southeastern U.S. have the highest prevalence of Alzheimer's dementia; eight of the 10 counties (with at least 10,000 older adults) with the highest prevalence are in the East and Southeast.”

In these regions, older people and Black and Hispanic residents - groups that are at higher risk of Alzheimer's dementia - comprise larger percentages of the population.
“In these regions, older people and Black and Hispanic residents — groups that are at higher risk of Alzheimer's dementia — comprise larger percentages of the population (see Racial and Ethnic Differences in the Prevalence of Alzheimer's and Other Dementias).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
