How to read this
Office density is a starting question, not an answer. A county with few offices per resident maysignal room for another practice — or it may reflect low incomes, an aging population, high commercial rents, or patients who leave the county for care. Density tells you where to look; it doesn’t tell you whether to move. That’s why this page shows the raw evidence and its source instead of compressing it into a single “opportunity score” that hides its own assumptions.
For national context: the U.S. overall runs 40.6 dentist offices per 100,000 residents. Marin County is at 67.2.
