## People represented in the records

The public collection contains **8,047 person and professional records**: 2,704 person records, 5,321 clinician records, and 22 official records. Professional location and public activity do not establish residence. The number of distinct county residents represented is **not established**; these records must not be counted as the county population.

The professional-license subset contains 2,679 real-estate license records associated with Marin mailing locations. Google reviewer profiles are counted separately from person records and do not establish that the reviewer lives in Marin.

The collection also contains 36 person-contact source records whose identifying fields are restricted. These source records are counted separately from public person and professional records.

## Object classes

**1,072,319 public source records across 97 classes**, as of November 01, 2026 at 11:27 PM PST. The class links open current counts and individual records. Counts describe stored source records; multiple sources can describe the same real-world thing. A Google Places result returned for a Marin search does not, by itself, establish a location in the county.
