How Martinez compares with the U.S.

Martinez has 125 clinicians in Nurse Practitioner - Family per 100,000 residents, about 1.8 times the U.S. rate of 71.

That is 46 active clinicians in Nurse Practitioner - Family with a practice address in Martinez, for a population of 36,903.

The California rate is 43 per 100,000 residents.

What these numbers mean

Clinicians per 100,000 residents compares places of different sizes. We count active clinicians who list a practice address in the area in the federal NPI registry (NPPES) and divide by the number of people who live there, according to the U.S. Census Bureau. The U.S. rate is the same calculation for the whole country.

A higher number does not mean it is easier to get an appointment, that wait times are shorter, or that care is better. It also does not show how many clinicians are accepting new patients or which insurance plans they take. A lower number does not by itself mean there is a shortage.

City counts use the city name in each clinician's practice address. That postal city can cover a larger or smaller area than the city limits the Census Bureau uses for population, and many clinicians list only one address even if they work in several places. Cities with hospitals or large medical centers often list more specialists than the number of residents alone would suggest, because patients also come from nearby areas.

Too few clinicians in Nurse Practitioner - Family in Martinez are listed in the CMS Medicare file to report Medicare assignment or telehealth shares.

These figures summarize public federal data. They do not measure quality of care, appointment availability, or whether a clinician accepts your insurance or new patients. Registry addresses can be out of date. Please confirm details directly with the office and your plan. This information is not medical advice.
