Plymouth County coverage
The share of 59,621 parcels carrying each field, with the Iowa average (all 99 counties with data, weighted by record count) beside it.
| Field | Plymouth County | Iowa average |

| Parcels | 59,621 | — |
| Situs address | 30.0% | 47.6% |

| Owner name | 49.2% | 62.5% |

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 Plymouth 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 Plymouth 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.
