States with the Most Arthritis

More than 4 in 10 adults in West Virginia (41.22%) say a doctor has told them they have some form of arthritis — the highest rate in the country, and nearly double the 21.2% in Texas, which ranks last. That spread is real but notably tighter than what we see on some of our other health maps: the gap from #1 to #50 here is roughly two-to-one, where diagnosed depression, for example, ran past that. Arthritis, it turns out, is one of the more evenly distributed conditions we track — but where it does concentrate, the pattern is unmistakable.

The top of this map is anchored by Appalachia and the Mid-South. West Virginia leads, followed by Alabama (34.64%), Maine (34.3%), Kentucky (34.27%), and Tennessee (33.2%). Maine is the one outlier in that group geographically, but the rest form a tight regional cluster that shows up again and again in our data. The bottom of the list leans the other way: Utah (21.71%), California (21.28%), and Texas (21.2%) post the three lowest rates — generally younger states where a larger share of the population is simply further from the ages when arthritis becomes common.

That age point is the key to reading this map honestly. Arthritis is strongly tied to getting older, so a state's rank partly reflects its age structure, not just its health. States with older populations will tend to rank higher almost mechanically, while states with younger populations like Texas and Utah will tend to rank lower. The metric also captures diagnosed arthritis — adults who say a doctor told them they have it — which folds together genuine prevalence and how much people are seeing providers. So a high rank likely reflects a mix of an older population and more medical contact, rather than any single cause.

What stands out most is how consistently West Virginia lands at the very top. It isn't only #1 for arthritis — in our other CDC maps it's also #1 for obesity (41.4%), #1 for diabetes (18.36%), #1 for depression (30.22%), #1 for adult smokers (20.78%), and #1 for the worst self-rated health (26.31%). A small cluster of Appalachian states keeps topping one health ranking after another, and arthritis fits squarely into that picture — the kinds of conditions that tend to travel together, may reflect shared underlying factors like age, occupation, and weight, and reinforce one another over a lifetime.

A note on method: every state here comes from the same CDC survey (BRFSS), one year (2024), one definition, so the 50-state comparison is apples-to-apples. The one exception is Tennessee, shown with its 2023 value, because CDC hadn't released a 2024 figure for it; it's flagged on the row. Because these are self-reported diagnoses, the map measures where arthritis is most recognized and recorded, which is closely related to — but not exactly the same as — where it's most common. The numbers are CDC's; the ranking and analysis are ours.
