How Sunnyvale compares with the U.S.

Sunnyvale has 12 clinicians in Registered Nurse - Case Management per 100,000 residents, 7.0 times the U.S. rate of 1.7.

That is 18 active clinicians in Registered Nurse - Case Management with a practice address in Sunnyvale, for a population of 154,236.

The California rate is 2.6 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.

None of the clinicians in Registered Nurse - Case Management in Sunnyvale are listed in the CMS Medicare file.

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 Registry addresses can be out of date.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.
