Founder Data Report84,523 Dental Practices Have Grown Past Four People. 544 Have Reached Fifty.
You can’t afford to risk your business without a Sidekick at your side.
Census sorts every American workplace that meets a payroll into 970 trades and counts them by size. In some trades the ladder keeps going. In most of them it stops one rung up.
The Census Bureau counts every American workplace that meets a payroll and files it by trade and by size. Set the tiny ones aside — everything under five people — and ask the question the data answers cleanly and almost nobody asks out loud: of the workplaces in your trade that already cleared that bar, how many ever got to fifty? In dentistry the answer is 544. There are 135,665 dental practices in the country, 84,523 of them employ five people or more, and 544 of those have reached fifty — 0.6%. Across all trades the same figure is 12.08%. In nail salons it is 0.1%: 15 salons out of 11,845. In skilled nursing it is 72.9%. The ladder above your head is not the one everyone else is climbing, and in most trades it is a great deal shorter than the story suggests.
- Of America’s 3,721,692 workplaces with five or more people, 449,688 — 12.1% — have fifty or more.
- That average hides a range from 0.1% to 72.9% across the 182 trades with at least 10,000 workplaces each. The median trade sits at 7.2%.
- In 31 of those 182 trades, fewer than one in fifty of the workplaces that got past four people has reached fifty.
- Dentistry is the largest example: 84,523 practices past four people, 544 at fifty or more.
- Being a trade full of tiny shops and being a trade with no ladder are not the same thing. Pharmacies and new car dealers are both about 15% tiny, but 1.9% of pharmacies past four people have reached fifty against 47.5% of car dealers.
The question your trade already answered
The measure is deliberately blunt. Take every workplace in a trade that employs at least five people — so the one-person operations and the husband-and-wife shops are already out of the count — and work out what share of them employ fifty or more. Nationally that is 12.08%: 449,688 workplaces of fifty-plus out of 3,721,692 that are past the tiny band. It is a plain statement about what the trade looks like, and the trades do not look remotely alike. Among the 182 trades with at least 10,000 workplaces apiece — together four in five of all American workplaces — the figure runs from 0.1% to 72.9%.
On a common 0–75% axis. Each bar is the share of that trade’s five-or-more workplaces that employ fifty or more; orange marks the trades above the national 12.1%, slate those below. The sub-label gives the number of workplaces each share is computed on.

Being small and having nowhere to go are different problems
The obvious guess is that these are the same fact wearing two hats — that a trade made of tiny shops is a trade with no ladder. It is not. Across the 182 trades the two measures correlate at just −0.38, which is a lean, not a rule, and the exceptions are the interesting part. Pharmacies and new car dealerships are structurally alike at the bottom: 18.4% of pharmacies and 14.1% of car dealerships have fewer than five people, both well under the national 55.5%. Above that line they could not be less alike. 648 of the 34,116 pharmacies past four people have reached fifty — 1.9%. For car dealers it is 8,940 of 18,828, or 47.5%. Same floor, and one of them has a ceiling twenty-five times higher.
Four trades that are all roughly 13–18% tiny. The slate dot is the share of the whole trade under five people; the orange dot is the share of its five-or-more workplaces that reached fifty. Both are percentages, so they share the 0–100 track. The slate dots nearly touch. The orange dots do not.

In 31 of America’s 182 biggest trades, fewer than one workplace in fifty ever gets past fifty people. That is not a shortage of ambition. That is the shape of the trade.
Most trades stop at the second rung
Sorted by how far the ladder goes, the 182 trades pile up at the bottom. 31 of them are under 2%. Another 34 sit between 2% and 5%, so 65 trades — more than a third of the set — are places where fewer than one in twenty of the workplaces that got past four people has reached fifty. Only 11 trades are above 30%, and they are mostly trades where fifty people is the minimum viable unit rather than an achievement: nursing homes, supermarkets, schools, temp agencies. The median trade sits at 7.2%.
One bar, five parts, together all 182 trades with at least 10,000 workplaces. The number on each segment is how many trades fall in that band, and every band is named in the legend.

What this number is, and what it is not
This is a photograph, not a film. It is the standing composition of each trade in the week of March 12, 2023 — not the odds that any particular business grows. A trade where 0.6% of the non-tiny workplaces are large is telling you how rare large is there; it is not telling you that your practice has a 0.6% chance of getting there. Three more things worth holding onto. Census counts workplaces, not companies: a chain with 400 branches is 400 workplaces here, which is exactly why the fifty-plus counts in retail and food are as high as they are. It covers employers only, so the millions of businesses with no payroll at all are nowhere in this file. And a handful of size cells are withheld for disclosure; assuming every withheld cell is a large one moves the numbers above by at most 0.16 of a percentage point, which changes no ranking here.
All three are the same calculation on the same file: the share of that trade’s five-or-more workplaces that employ fifty or more, from Census County Business Patterns 2023.

None of this is an argument for staying small, and it is certainly not an argument that you picked wrong. It is an argument for knowing which game you are in before you judge yourself for the score. If you run a dental practice with nine people and you have spent three years feeling you should be at thirty by now, the file says 84,000 practices are standing exactly where you are and 544 in the whole country are where you think you ought to be. That is worth knowing — not because it lowers the bar, but because the plan for getting somewhere rare is a different plan from the one for getting somewhere ordinary, and most owners are running the second plan while holding themselves to the first. Pick the number you are actually aiming at, then find out how many people in your trade are standing on it.
Frequently Asked Questions
What share of American workplaces have fifty or more employees?
12.1% of the ones that already have at least five. In the Census Bureau’s County Business Patterns 2023, 3,721,692 American workplaces employed five people or more and 449,688 of those employed fifty or more. Measured against all 8,361,342 workplaces, including the tiny ones, the fifty-plus share is 5.4%.
Which trade has the fewest large workplaces?
Of the 182 trades with at least 10,000 workplaces, nail salons. 11,845 nail salons employ five people or more and 15 of them employ fifty or more — 0.13%. Offices of dentists is the largest trade near the bottom: 84,523 practices past four people, 544 at fifty or more.
Does a trade full of small businesses always lack big ones?
No. The two measures correlate at only −0.38 across the 182 largest trades. Pharmacies and new car dealerships are both about 15% tiny, but 1.9% of pharmacies with five or more people have reached fifty against 47.5% of car dealerships — the same floor with very different ceilings.
Does this measure my chances of growing?
No. It is a cross-section — the composition of each trade in the week of March 12, 2023 — not the path of any business through it. It tells you how common large workplaces are in your trade, which is a different and more reliable thing than a growth probability. Census publishes no cohort here.
What counts as a workplace in this data?
An establishment: a single physical location with paid employees and an Employer Identification Number. A company running 400 branches appears as 400 establishments, not one. The file excludes businesses with no employees, crop and animal production, private households, the Postal Service and most government, and it measures employment in the week of March 12.
