Ada County coverage
The share of 221,250 parcels carrying each field, with the Idaho average (all 44 counties with data, weighted by record count) beside it.
| Field | Ada County | Idaho average |
|---|---|---|
| Parcels | 221,250 | — |
| Situs address | 99.8% | 41.0% |
| Geocoded (usable coordinate) | 99.9% | 51.3% |
| Owner name | 96.8% | 42.5% |
| Assessed value above zero | 87.8% | 34.9% |
| Parcel polygon | 49.5% | 38.8% |
Situs address counts records with a non-empty street address; geocoded counts records with a non-zero coordinate; owner name counts records with a non-empty owner; assessed value counts records whose total assessed value is above zero; parcel polygon counts records with geometry attached. A county with many records but a low polygon share has coordinates and attributes, not boundaries. A field below 1% is one the county source does not publish.
What a Ada County parcel record contains
Every PropRaven parcel record shares one national schema. The families below are the ones the data dictionary documents; the coverage table above tells you how fully each is populated for Ada County, and a field that is empty for a county is empty because the county source does not publish it, not because it was dropped.
