Caveats
- ACS 5-year vintages overlap by four years, so consecutive estimates are not independent measurements and short windows understate the real separation.
- Affordability ratios are computed by this platform from two published series, not published by either source. The monthly value or rent series is averaged over the survey year to match the annual income denominator.
- Zillow's rent index begins in 2015 and covers far fewer places than its home-value index, so any rent figure rests on a thinner base — and ranks against a smaller cohort — than a value figure.
- HUD publishes income limits per county, so every AMI-based figure here is a county figure. HUD does not sanction allocating one down to a municipality.
- Some metrics rank this region against fewer peers than the level contains, because not every region carries every metric. Compare ranks only within the cohort size each one reports.
