How density varies inside Delaware

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 39 places in Delaware.

Delaware has 4,451 licensed providers with a registered practice address, across 13 licence types.

Delaware ranks 48th of 56 states and territories by the number of registered providers in this field.

By licence type the breakdown is clinical social worker (936), mental health counselor (802), addiction (substance use disorder) counselor (532), school psychologist (411), with 9 further types making up the remainder.

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.

The three largest concentrations are Wilmington (2,149), Newark (1,036), Dover (621).

One caveat on reading these numbers: the registry records where a provider registered an address, not where they see clients day to day, and addresses are not always kept current. It also says nothing about whether someone is taking new clients.

How Delaware 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 Delaware. 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 Delaware. Annual registrations in 2025 were 26% 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

80.3% of registered licensed providers in Delaware 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.

5 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.
