About this index & how it's been checked
The Aging Vulnerability Index (AVI) is this platform's own construction, modeled on the CDC/ATSDR Social Vulnerability Index methodology but not a CDC product and not independently validated. It combines Census ACS data on the population 65 and older — demographic aging pressure, economic precarity, health/disability/isolation, and housing/transportation burden — into a single percentile ranking of U.S. counties. The underlying inputs are official Census data; the index construction and weighting are this platform's own.
Reference-county check
A face-validity check against real counties with well-documented age profiles — the same method used to calibrate this platform's seasonal-community threshold. Higher percentile = more aging-vulnerable.

Where this is
Shading: Aging Vulnerability Index
Lower (1 to 22)Lower-middle (23 to 44)Middle (46 to 57)Upper-middle (60 to 79)Higher (79 to 98)
Each unit is shaded by its Aging Vulnerability Index value and grouped into equal-count bands (quantiles) against the other units shown — lighter = lower, darker = higher. It ranks position among the units in view; it does not grade places, and the ranges shift with which units are shown.
The map is bounded to this parent geography — it shows the selected unit among its own siblings only, the same depth rule the drill-down uses. Shading ranks position on the measure among the units shown; it does not grade places.
Median county: 51st percentile (among all U.S. counties).
These counties span the 1st percentile to the 98th percentile. The width of that range is the internal disparity.
Jefferson County is marked below — Below the median.
Widest spread across these counties: Housing & Transportation, 65+ — this theme most separates the higher- and lower-ranked counties here.
AVI ranks each county's position relative to a comparison set; it is not averaged into one number for the area, because percentiles do not average meaningfully. The distribution — median, range, and shape below — is the summary.
Jefferson County — by county subdivision
Median county subdivision: 46th percentile (among all U.S. county subdivisions).
These county subdivisions span the 5th percentile to the 61st percentile. The width of that range is the internal disparity.
Widest spread across these county subdivisions: Demographic Aging Pressure — this theme most separates the higher- and lower-ranked county subdivisions here.
AVI ranks each county subdivision's position relative to a comparison set; it is not averaged into one number for the area, because percentiles do not average meaningfully. The distribution — median, range, and shape below — is the summary.

AVI = a candidate Aging Vulnerability Index, computed by this platform from American Community Survey 2020–2024 5-year estimates, following the same method shape (percentile rank -> theme sum -> re-rank -> overall) as the CDC/ATSDR SVI this platform also recomputes — but AVI itself has no published ground truth to validate against. It is a first-cut, directional design. Percentiles rank each county against all U.S. counties.
Several of AVI's 12 input signals carry a documented high margin of error at this grain (most notably lack of health insurance, 65+) and are kept in the index with a flag rather than dropped, to preserve variable coverage. A county's flag count (shown per-county above) is a direct measure of how much its rank should be read as directional rather than precise.
