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 32)Lower-middle (32 to 45)Middle (46 to 63)Upper-middle (64 to 81)Higher (82 to 99)No data
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.
The panel shows the county overview. Click a tract for its own percentile and theme scores — the county overview stays visible alongside it for comparison.
Median tract: 59th percentile (among all U.S. tracts).
These tracts span the 1st percentile to the 99th percentile. The width of that range is the internal disparity.
Widest spread across these tracts: Economic Precarity, 65+ — this theme most separates the higher- and lower-ranked tracts here.
AVI ranks each tract'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.

These carry no percentile. Excluded from the bands, median and range above, and never shown as a low score.
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 tract against all U.S. tracts.
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 tract's flag count (shown per-tract above) is a direct measure of how much its rank should be read as directional rather than precise.
