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.

  • ✓ Sumter County, FL — 79.8th percentile (expected HIGH, The Villages — often cited as the oldest-median-age U.S. county)
  • ✓ Charlotte County, FL — 90.8th percentile (expected HIGH, Retirement destination)
  • ✓ Citrus County, FL — 88.1th percentile (expected HIGH, Retirement destination)
  • ✓ Highlands County, FL — 95.9th percentile (expected HIGH, Retirement destination)
  • ✓ Brazos County, TX — 17.0th percentile (expected LOW, Texas A&M)
  • ✓ Story County, IA — 8.9th percentile (expected LOW, Iowa State)
  • ✓ Whitman County, WA — 10.3th percentile (expected LOW, Washington State University)

Where this is
Shading: Aging Vulnerability Index
Lower (5 to 12)Lower-middle (12 to 32)Middle (34 to 47)Upper-middle (48 to 54)Higher (58 to 97)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.

Widest spread across these county subdivisions: Economic Precarity, 65+ — 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.

1 county unranked — insufficient data
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 county against all U.S. county subdivisions.
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.
