How density varies inside California

Each bar is the number of places at that level of provider density. A long right tail means a few places carry far more providers per resident than the rest of the state.

Distribution across 431 places in California.

There are 249,747 licensed providers registered in California. The two most common licence types are marriage & family therapist (60,309) and clinical social worker (36,525).

California ranks 1st of 56 states and territories by the number of registered providers in this field.

The largest single group is marriage & family therapist, at 60,309 providers or 24% of the total. Licence titles vary between states for what is often similar training and scope, so the mix here partly reflects how California licenses its providers.

13 distinct licence types are registered here. The letters after a provider's name describe their training route rather than a ranking, and several of them do substantially overlapping work.

Providers are registered in 960 distinct places across California. The map shows the ZIP codes with the highest counts.

These counts come from the federal NPI registry. A provider appears here if they hold an active NPI with a practice address in this area — it does not mean they are currently accepting new clients, and the registry does not record insurance, fees or availability.

How California got here

new registrations per year

Each registration carries the year it was issued, so the registry doubles as a record of when this workforce grew in California. A rising line means the constraint is easing; a flat one means today's shortage is likely to be next year's too.

New registrations per year. licensed providers in California. Annual registrations in 2025 were 20% higher than in 2008. The final bar is faded because 2026 is still in progress. Starts at 2008 on purpose. The NPI system launched in 2006– 2007 and the whole profession registered at once, so those two years are an artefact of the rollout rather than a measure of anything. Including them would make the following year look like a collapse.

Who they are

self-reported to CMS

75.3% of registered licensed providers in California are women. Nationally the figure varies a great deal by licence type — occupational therapy at one end, psychiatry at the other. See the national breakdown.

You can filter any city list on this site by gender. We show it because it is one of the most common things people search for and, for some kinds of work, a real need — but it is only ever a filter here, never a ranking.

44 places have no per-resident figure. Those are office districts inside a larger urban area, rural towns whose practices serve a whole region, or places where most registrations share one employer's address — dividing by the resident population there produces a number that looks precise and describes nothing. The provider counts are unaffected; the test is described in the methodology.
