How healthy is the environment around your home?
HomeNHealthy combines public environmental and housing datasets into a transparent city-level index. It measures geography—not the condition of an individual house.
75 cities. Four public-data signals.
Scores combine an AirNow AQI snapshot, EPA drinking-water compliance, NOAA climate moisture pressure and Census housing-age data. Each component is labeled as a proxy and documented in the methodology.
| Rank | City | Score | AQI now | Water | Moisture | Median build | Move |
|---|---|---|---|---|---|---|---|
| #1 | Sioux Falls, SD | 82.4 | 22 | 95% | 52.3 | 1993 | — |
| #2 | Austin, TX | 81.0 | 36 | 91% | 39.9 | 1994 | — |

Environmental context, not a diagnosis.
Air quality snapshot
Current AirNow AQI for the closest reporting area. This is a current outdoor environmental snapshot, not a claim about indoor air.
How air data works →Drinking-water compliance
Share of active community water systems in the state without a current health-based violation in EPA ECHO/SDWIS.
How water data works →Climate moisture pressure
A climate proxy derived from NOAA warm-season temperature and precipitation normals. It is not a mold measurement.
How climate data works →Housing-age proxy
Census median year built. Older housing can be excellent; this represents age-related maintenance context only.
