Founder Data Report98.6% of America’s Small Employers Operate in Exactly One State — and It Takes 300 Employees to Change That
You can’t afford to risk your business without a Sidekick at your side.
Every founder eventually wonders when a business stops being local. The Census Bureau counts each company once in every state it operates in, and that quirk turns out to be a measurement: it says the average company adds locations long before it adds states, and does not average a second state until it passes 300 employees.
The Census Bureau lists an employer firm once in every state where it operates. Nationally there are 6,395,635 employer firms and 6,604,618 state listings — an excess of 208,983. Because a company in two states adds one to that excess and a company in five adds four, the excess is a ceiling on how many companies are multi-state at all: at most 3.3% of all employer firms, and at most 1.4% of those under 500 employees. Put the other way, at least 98.6% of America’s small employers operate in exactly one state. The average number of states per firm rises from 1.0003 in the smallest size band to 21.6 in the largest, and does not reach two until the 300-399-employee band.
- There are 6,395,635 U.S. employer firms and 6,604,618 state listings of them; the 208,983 extra listings are companies counted in a second or third state.
- At least 98.6% of firms under 500 employees, and at least 96.7% of all employer firms, operate in exactly one state.
- The average firm runs two locations by the 100-149-employee band but does not average two states until 300-399.
- At 5,000-plus employees the average firm runs 404 locations across 21.6 states — 18.7 locations in each.
- Growing adds locations roughly eighteen times faster than it adds states. Companies densify before they spread.
Almost every employer in the country is a one-state business
Start with the two counts. The Census Bureau’s 2022 business register holds 6,395,635 employer firms — companies with at least one employee on a payroll. Sum the same file’s state-by-state firm counts and you get 6,604,618, which is 208,983 higher. Nothing is wrong with either number. A company that operates in Ohio and Kentucky appears in the Ohio row and the Kentucky row, so the state sums count it twice. Every other measure in the file — locations, employees, payroll — adds across the states exactly, which is how you can be sure the firm gap is double-counting and not an error.
Drawn to scale across every state listing in the file. Orange is the count of states beyond a firm’s first; slate is the single-state base. The orange slice is a ceiling on multi-state companies rather than a count of them, because one firm operating in four states contributes three listings to it.

Below 500 employees the ceiling barely lifts off the floor
Split the firms into the Census Bureau’s own size bands and the same arithmetic gives a ceiling for each one. In the smallest band — companies with fewer than five employees, 4,029,041 of them — at most 0.03% operate in more than one state. That is about one company in 3,800. The ceiling stays under one percent until 15 employees, under five percent until 40, and under ten percent until 75. It is only in the 100-149-employee band that it reaches 26%. For the overwhelming majority of American employers, multi-state operation is not a live question.
Orange bar length is the ceiling itself, on a shared 0–28% scale, so the bars are comparable to each other. Every figure is an upper bound derived from the Census firm count identity, not a survey estimate: the true share is at or below it. The bound stops being informative above 300 employees, where it exceeds 100%. Bands shown run from under five employees to 100-149; the bound is 44% at 150-199 employees and 70% at 200-299, left off the chart so the smallest bands stay legible against each other.

Above 500 employees the ladder finally steepens
Past the small-business threshold the average takes over from the ceiling, and it climbs fast. Firms with 500-749 employees average 3.1 states. By 1,500-1,999 it is 6.7, and in the top band — the 2,262 firms with 5,000 or more employees — it is 21.6. Those 2,262 companies are 0.04% of all employer firms and they hold 36.3% of private-sector employment. The average rises without a single reversal across all 23 size bands in the file, which is what makes it a ladder rather than a scatter.
Orange is the count of states, on a shared 0–22 scale. The figure is the Census state-listing sum for the band divided by its national firm count, which is exactly the mean number of states per firm. It is a mean, so a handful of national chains pull it well above the typical firm in the band.

Four hundred times the locations buys twenty-one times the states, not four hundred times. Scale buys depth inside a market long before it buys new ones.
Companies densify before they spread
The more useful reading comes from putting the two counts side by side. Across the whole size range the average number of locations per firm multiplies by roughly four hundred — from 1.00 in the smallest band to 404 in the largest — while the average number of states multiplies by only 21.6. Locations therefore arrive roughly eighteen times faster than states do. You can see it inside the small-business range on its own: a firm with 400-499 employees averages 9.1 locations but only 2.5 states, which is 3.7 locations in each state it is in. For an owner deciding where the next site goes, the pattern in the data is that companies go deeper before they go wider — and the reasons are the ones you would guess: one set of licences, one labour market, one drive time.
Slate is the count of locations per state, on a shared 0–4 scale: the band’s average locations per firm divided by its average states per firm. It rises without a reversal across every one of the 23 bands in the file; the 16 bands under 500 employees are shown here, and the series continues to 18.7 locations per state in the 5,000-plus band.

One caveat worth keeping. These counts cover employer firms only — businesses with at least one employee on a payroll. The millions of American businesses with no employees are not in this file at all, and essentially all of them are single-state. Including them would push the single-state share higher, not lower, so the 98.6% floor is conservative. And a state listing means a payroll presence, not a customer: a two-person consultancy in Boise billing clients in forty states is a one-state business here, correctly, because that is what the file measures.
Frequently Asked Questions
How many U.S. companies operate in more than one state?
At most 3.3% of the 6,395,635 U.S. employer firms in the Census Bureau's 2022 Statistics of U.S. Businesses. The state-by-state firm counts sum to 6,604,618, an excess of 208,983, and because a firm in three states adds two to that excess, the excess is an upper bound on the number of multi-state firms rather than a count of them.
What share of small businesses operate in only one state?
At least 98.6% of employer firms with fewer than 500 employees. Among firms with fewer than 20 employees the floor is 99.8%, and among those with fewer than five it is 99.97%. Non-employer businesses are excluded from the file and would raise these figures.
At what size does a company typically expand to a second state?
The average number of states per firm does not reach two until the 300-399-employee band. Below that it is closer to one than to two at every size: 1.00 under five employees, 1.09 at 50 to 74, and 1.44 at 150 to 199.
Do companies add locations or states first?
Locations, by a wide margin. The average firm passes two locations in the 100-149-employee band but does not pass two states until 300-399. Across the full size range average locations per firm multiply by about 403 while average states per firm multiply by 21.6.
How many states does a large company operate in?
The 2,262 U.S. firms with 5,000 or more employees average 21.6 states and 404 locations — about 18.7 locations in each state. They are 0.04% of employer firms and hold 36.3% of private-sector employment.
