Mobility Disability by County — US Rankings
CDC PLACES 2023 · Age-adjusted prevalence · All 3,144 US counties
Mobility disability is captured by a single BRFSS question on serious difficulty walking or climbing stairs. PLACES age-adjusts the estimate. After age adjustment, the county pattern tracks decades of occupational injury, obesity prevalence, arthritis prevalence, and access to physical therapy. The highest-prevalence counties cluster in central Appalachia and the rural South — the same geography that shows up across most chronic-disease rankings, which is not coincidence.
How this ranking is built
Source: CDC PLACES 2023 release. Methodology: BRFSS survey responses pooled across years, fitted with a small-area statistical model, age-adjusted to the 2000 US standard population. Confidence intervals (95%) are shown for each county — wider intervals indicate more uncertainty in the modeled estimate, typically driven by smaller populations.

What this ranking suggests
Mobility is the most concrete of the disability measures: it is what residents experience getting through a day. Read it alongside the ARTHRITIS ranking (a major upstream driver) and the LPA (physical inactivity) ranking (a major downstream consequence).
Methodology notes & limitations
Estimates are statistical model outputs, not direct measurements. Small counties have wider confidence intervals; treat narrow rank differences in those rows as within-noise. Counties where the underlying population is too small to support modeling are suppressed entirely (about 1% of US counties). All measures are age-adjusted to the 2000 US standard population. The PLACES dataset uses BRFSS self-reported data — self-report introduces known direction-of-bias in some measures (BMI is under-reported; binge drinking is under-reported), but the bias is roughly uniform across counties so ranking comparability is preserved. See the methodology page for full data-pipeline documentation.
