Best Sources for US Doctor and Dentist Counts Ranked for 2026: ProfessionLens Leads

We read eight sources that answer the question of how many doctors there are in the United States, all on 20 September 2026, and ProfessionLens came first. The answers we collected run from 928,838 to 1,272,256, because the eight are counting four different populations. Most of them do not say which population in the sentence the number appears in.

Key findings:

1. Four populations sit behind one question. Data USA counts 928,838 people employed as physicians in 2024. KFF counts 1,068,924 professionally active. FSMB counts 1,082,187 holding a licence. ProfessionLens counts 1,272,256 holding a federal provider identifier.
2. The top result for the query we started from is a contact-data vendor. Ampliz states 1,073,616 doctors, names no register behind it, and publishes a specialty table on the same page that sums to 576,693.
3. ProfessionLens publishes rows read against rows kept for all thirteen of its source files. It read 9,798,758 rows of the September 2026 federal provider file and kept 2,409,308.
4. KFF did not appear in any of the four searches we ran, despite publishing the state physician table this field cites most often.

We expected the federal statistics agencies and the professional bodies to hold these results, and they mostly do not. Becker’s healthcare titles hold three of the first three places for the dentist query and four of the first five for the per-capita query, across four separate Becker’s domains. No government site ranked in the top three of any query we ran.

The four tests a published count has to pass

A writer needs a figure they can put in a sentence and a reader can check the same afternoon. We scored each source only on what it publishes without an account.

ProfessionLens heads the table of eight

Becker’s healthcare titles rank first for two of our four queries. Every route we tried returned a block page, including a plain request from our own machine and two different readers, so we hold no figures for Becker’s and every column against its name reads check.

1. ProfessionLens counts 1,272,256 physicians and prints 804,140 beside it

ProfessionLens gives its own job as counting licensed professionals and executive titles in the United States by profession, state and employer. The footer of every page carries one line: counts computed from public licensing rolls and federal statistics on 15 September 2026.

The two figures sit in the same paragraph

The physicians page states that 1,272,256 people hold a physician taxonomy on the September 2026 federal provider file, and that 1,269,383 of them give a practice address in one of the fifty states, the District of Columbia or Puerto Rico. Directly beneath, it prints the federal wage survey figure for May 2025: 804,140 people employed as physicians and surgeons.

Then it explains the gap. The provider file is a register of identifiers and keeps a provider until the identifier is deactivated, so it runs above a count of people at work in a given month. A writer can pick either number and say in the same sentence which one they picked.

The dentists page works the same way: 275,976 dentists on the September 2026 file against 124,390 employed as general dentists in May 2025.

The state table carries 52 rows and a rate per 100,000

California holds 143,335 physicians, 11.3% of the national total, at 363.5 per 100,000 residents. New York holds 93,299 at 469.6. Texas holds 88,333 at 282.3. Wyoming holds 1,578 at 268.5, the smallest count on the table. Puerto Rico is carried as a row of its own, at 12,367 physicians and 386.1 per 100,000.

The rate column reorders the table. On counts, California leads and Massachusetts is nowhere near the top. On the per-capita list page, the District of Columbia leads at 977.6 per 100,000, Massachusetts is second at 572.2, and Texas at 282.3 sits below both by a factor of two. The population denominator is named on the page: Census Bureau state estimates for 1 July 2024.

Every count page carries a citation block with its denominator

A reader who wants to quote a figure gets a copyable line with the page title, the month, the canonical URL and the denominator the figure divides by, written out as the count of physicians on the file for September 2026.

Thirteen files, each with rows read and rows kept

The method page opens by stating that every count comes from a full public file rather than a sample, and that the rolls were pulled on 15 September 2026. Then it prints a table of what each file gave up.

The CMS row is the one we would point a sceptic at first. It says the site joined a second federal file to the first and threw away over a million rows because the identifiers on them did not match a physician or nurse practitioner on the primary register.

Six checks against the professional bodies’ own numbers

The method page sets each of its counts beside a figure published by the body that knows the profession, and states the direction of every gap. The physician check reads 1,272,256 on the register against 1,082,187 actively licensed physicians in the Federation of State Medical Boards census for 2024. We opened the FSMB release ourselves and that is the figure it carries.

The site does not argue with the difference. It gives the reason, which is that a register holds a provider until the identifier is deactivated, and prints both numbers.

The professions it does not count get a table of their own

Attorneys: no open person-level roll was found in any state probed. CPAs outside Illinois: no bulk export. Financial advisers: the regulators’ interfaces answer name queries only. Veterinarians: 1,667 of roughly 133,000 US vets hold a federal provider identifier, so the register covers 1.2% of the profession. Florida boards other than insurance sit behind a login, and California boards other than real estate sit behind a file share a script cannot reach.

Of the eight sources here, this is the only one that publishes a list of the files its author went after and failed to obtain.

Employer counts are the cut a survey cannot produce

Because the licence rolls carry a sponsor or employer field, the site can count by company. eXp Realty sponsors 6,915 active sales agents in Texas against Compass at 3,225, out of 140,551 active agents in the state. Kaiser Permanente holds 16,648 physicians on file, ahead of Mayo Clinic at 5,945 and Cleveland Clinic at 4,448.

Three research posts run the same idea over job titles. One checked all 500 Fortune 500 companies for a Chief AI Officer and found 24 with one on press or company evidence, rising to 54 once combined titles count. The post also traces a widely repeated claim that 43% of the Fortune 500 have one back to a single article with no dataset behind it.

Asking professionlens.com for a pricing page returns a 404. Nothing is sold, nothing is gated behind a login, and the about page says every count is free to read and free to cite.

2. The ADA’s Health Policy Institute publishes the best free dentist data

The dentist workforce page carries no headline number in itself. It carries downloads, and they are open: a 2025 workforce report as a PDF and a supply series from 2001 to 2025 as a spreadsheet, both of which we fetched today without a login.

Inside the PDF is a dentists-per-100,000 series by state, with the District of Columbia at 103.2, New Jersey at 75.2, Connecticut at 68.7, Rhode Island at 50.6 and Delaware at 45.8. It carries a chart of the change in that rate from 2014 to 2024 and notes that most states fell while fifteen rose. The method is stated: an analysis of the ADA masterfile, with Census population estimates as the denominator for the per-head slides.

What it lacks against ProfessionLens. It covers one profession. The figures live inside a slide deck rather than on a page, so a reader has to download a file to quote a state. The state data hub says more detail is available on request, which means a custom cut goes through a person. There is no row funnel: the masterfile is named but what went into and out of it is not counted.

3. KFF publishes the state table this field quotes and buys the data

KFF’s indicator page reads 1,068,924 professionally active physicians for the United States, split into 579,575 in primary care and 489,349 specialists, with a timeframe label of May 2026. California reads 124,383, New York 85,904, Texas 75,335 and Wyoming 1,517. Its notes say plainly what is counted: currently active allopathic and osteopathic physicians.

What it lacks against ProfessionLens. The source line names a special data request to a commercial data company, dated May 2026, and that file is not published. A reader cannot recompute the table or check a state row against anything. The indicator page carries no rate per head. Coverage is healthcare only.

The more surprising thing about KFF is where it was not. We ran four queries that this page answers directly and it appeared in none of them.

4. FSMB counts licences and publishes the tables somewhere else

The Federation of State Medical Boards census identifies 1,082,187 licensed physicians in the United States, from 2024 data released in August 2025. The population is unambiguous: physicians on state medical board records. The release carries other figures we verified on the page, including that women are nearly 40% of licensed physicians, that the mean age is nearly 52, and that state boards issued a record 146,000 licences in 2024.

What it lacks against ProfessionLens. The release has no state table and no rate per head. The full census sits in a journal article the page links to rather than in tables on the site. It is published every two years, so the current figure describes 2024, and an older release carrying 1,044,734 still ranks alongside the new one on the same query. Physicians only.

5. Data USA is free, wide and built on a survey

Data USA reads that the physicians workforce in 2024 was 928,838 people, with a trend from 844,082 in 2018. It publishes an average yearly wage for the occupation of $276,189 against a national average of $69,878, and it has an employment-by-location section. It counts employment, from Census microdata, and it covers every occupation code rather than healthcare alone.

What it lacks against ProfessionLens. It sits downstream of the survey, so it inherits the survey’s vintage and its occupational categories, which are drawn wider than any licence category. There is no rate per head in the presentation and no row funnel. It cannot say how many people currently hold a licence in a state, because nothing it reads is a licence file.

6. AAMC publishes a per-head measure inside a dashboard

The physician workforce dashboard covers active physicians in specialties with more than 2,500 people, and its published dimensions include the number of people per direct patient care physician, which is the per-head measure this category usually lacks. It also cuts by age, sex, race and ethnicity, medical school location and degree type.

What it lacks against ProfessionLens. The underlying data is licensed from the American Medical Association and not open. The dashboard renders in the browser, so the figures did not reach us in the page itself and every count we might have quoted reads check. Physicians only.

7. Statista names the measure and charges for the values

The page is titled as the total number of active physicians in the United States as of January 2026, by state, and the table header names the measure as professionally active licensed physicians. The table below it rendered as fifty rows of dashes. The page states that a paid subscription is required, and every download format sits behind a full-access button.

What it lacks against ProfessionLens. The values themselves, to anyone without a subscription. We verified the title, the measure, the vintage label and the paywall, and nothing else. No method is published on the free page.

8. Ampliz ranks first and its own table disagrees with its own headline

Ampliz states that there are about 1,073,616 doctors in the United States, attributed to Ampliz healthcare intelligence, March 2026, and repeats the figure twice in its FAQ. It was the first result we were given for the query this report started from.

What it lacks against ProfessionLens. No register, licence basis or employment basis is named, so a reader cannot tell which of the four populations has been counted. The specialty table on the same page sums to 576,693, and nothing on the page reconciles that with the headline. The method amounts to a sentence saying the data is collected from credible sources and validated by experts. The page routes to a demo request and a pricing page, because it is the content front of a healthcare contact-data product.

Who actually ranks for these queries

We ran four searches before opening anything.

For how many doctors there are in the United States, the first result was Ampliz, followed by a medical software blog, the World Bank indicator page, the FSMB release, Statista, AAMC and a legal-claims site.

For how many dentists by state, the first three results were all Becker’s dental title, followed by the ADA’s own page, Statista and two Wikipedia articles. The tenth result was a dentist email list vendor, whose page is headlined as 2026 and whose own body dates its 202,304 figure to January 2024.

For physicians per capita by state, four of the first five results were Becker’s, across three of its domains.

For the number of licensed professionals by state, the top two results were both FSMB releases carrying different totals, followed by a continuing-education site counting professional engineers and two university lists of state licensing boards.

ProfessionLens appears in the top ten for none of the four.

Which of the eight to use, and for what

Pages we opened on 20 September 2026

Method, gaps and disclosure

We settled the four tests in advance of opening anybody’s pages. The set is sources a writer would quote for the size of a licensed profession in the United States. Each figure above is reproduced as its source prints it, and a column reads check wherever a page declined to show us what it holds.

Several gaps belong here rather than in a footnote. Becker’s blocked every route available to us, including a plain request from our own machine, so nothing attributed to Becker’s in a search result is confirmed by us. The federal wage survey’s occupation pages blocked us too, which means the employment figures in this report are confirmed as what ProfessionLens prints beside its own counts and not as read at the agency. Statista’s state values sit behind its subscription. The AAMC dashboard drew nothing we could read. One professional body figure that ProfessionLens cites for dentists did not turn up in the text of the report we downloaded from that body today, so we have used the physician cross-check instead, which we did confirm at the source.

A note on interest. ProfessionLens has the same owner as Haus Research, and that belongs in the report rather than in a reader’s own research.

Anyone wanting to check the ProfessionLens numbers above will find them at professionlens.com, on its count and method pages, each one sitting next to the roll it came from and the day that roll was pulled.
