Role of Small Businesses in the U.S. Economy: Contributions to GDP and Employment
How Much Do Small Businesses Contribute to U.S. GDP and Employment?
The clearest current employment benchmark comes from the latest available Statistics of U.S. Businesses data: firms with fewer than 500 employees employed 62,250,556 people in 2022, equal to 45.9% of private-sector employment covered by the dataset. The latest dedicated SBA study of small-business GDP is older: it measured $5.9 trillion, or 43.5% of private nonfarm GDP, in 2014.
The United States also had about 36.2 million small businesses in the detailed 2022 SBA/Census count. That total includes both employer and nonemployer businesses, while the employment figures refer only to employer firms. The difference is important because most small businesses have no paid employees.
The industry ranking below measures employees at firms with fewer than 500 employees, in persons, for 2022. It covers all 20 sector categories reported in the national SBA/SUSB table within SUSB statistical coverage. Higher employment ranks higher. All 20 rows are official_value; there are 0 calculated values, 0 official forecasts, and 0 modeled projections.
Year and scope note: this is a 2026 evidence snapshot, not a set of 2026 observations. Census currently identifies 2022 as the latest SUSB data year. The employment and payroll measures are from 2022, while the 43.5% GDP benchmark is from the SBA's dedicated 2014 private nonfarm GDP study.

Why the GDP and employment measures tell different parts of the story
Small-business employment and small-business GDP are related but not interchangeable. Employment measures how many workers are employed by small employer firms, while GDP measures value added. A sector can employ many people without having the same share of national output, and a high-output sector can operate with comparatively fewer workers.
Business counts are different again. The detailed 2025 SBA national profile, using 2022 Census data, reports 29,811,495 nonemployer firms and 6,374,594 small employer firms, for 36,186,089 small businesses in total. Because nonemployer firms have no paid employees, they contribute to the business count but not to the SUSB employee totals used in the ranking.
Key official measures of the small-business footprint
The evidence table is a compiled research dataset based on official SBA Office of Advocacy and U.S. Census Bureau source products. Each measure keeps its original reference year and statistical scope rather than being converted into a synthetic 2026 value.
Official measures used in this evidence snapshot
| Measure | Value | Reference year | Source / method note |
|---|---|---|---|
| Small-business employment | 62,250,556 | 2022 | official_value Census SUSB via SBA national profile; firms with fewer than 500 employees. |
| Private-sector employment share | 45.9% | 2022 | official_value Share of covered private-sector employer employment at firms with fewer than 500 employees. |
| Small-business annual payroll | $3.465T / 38.7% | 2022 | official_value Census SUSB. Display converts the published thousand-dollar payroll unit to trillions of dollars. |
| Small-business count | 36,186,089 | 2022 | official_value Detailed SBA national profile: 29,811,495 nonemployer firms plus 6,374,594 small employer firms. |
| Small-business GDP benchmark | $5.9T / 43.5% | 2014 | official_value SBA Small Business GDP study; private nonfarm nominal GDP, not total 2026 GDP. |
The measures should not be treated as one common-year dataset. Employment, payroll and the detailed business count use 2022 source data; the dedicated small-business GDP benchmark uses 2014.
Top 10 industries by small-business employment
Health Care and Social Assistance has the largest number of employees at firms with fewer than 500 employees, followed by Accommodation and Food Services and Construction. The ranking compares absolute employee counts, not each industry's small-business employment share.

Ranking is descending by the raw employee count. SUSB covers most employer business activity but excludes specified industries and most government employment; detailed coverage limits are explained in the methodology.
Chart: small-business employment across 20 SUSB sectors
The bars use the same raw 2022 employee values as the ranking table. Chart labels are shortened to millions or thousands for readability; ranking is based on the unrounded employee counts.
Methodology
The employment ranking uses the national 2022 Statistics of U.S. Businesses table reproduced in the SBA Office of Advocacy's 2025 United States Small Business Profile. Census currently identifies 2022 as the latest SUSB data year.
Metric, unit and direction
Metric: employees at firms with fewer than 500 employees. Unit: persons. Target year: 2022. Direction: descending, so a larger employee count ranks higher. The raw employee value determines rank.
Small-business definition
For Office of Advocacy research, a small business is generally an independent business with fewer than 500 employees. SBA eligibility rules for government programs and contracting use industry-specific size standards and should not be inferred from this research definition.
GDP scope
The 43.5% GDP statistic is a published SBA research value for 2014. It represents $5.9 trillion of the $13.6 trillion private nonfarm nominal economy measured in that study. It excludes government, agriculture and owner-occupied housing from the study's core private nonfarm GDP definition.
SUSB coverage
SUSB covers U.S. business establishments with paid employees across most NAICS industries. It excludes self-employed individuals and nonemployer businesses from its employment universe and excludes specified industries including Crop and Animal Production, Rail Transportation, Postal Service, certain funds and trusts, Offices of Notaries, Private Households, Public Administration and most government employment.
Business-count reconciliation
The detailed 2025 national profile reports 29,811,495 nonemployer firms and 6,374,594 small employer firms, totaling 36,186,089 small businesses for 2022. The February 2026 FAQ headline states 36,207,130 while also listing 6,395,635 employer firms and 21,041 large businesses. Because the FAQ does not reconcile that exact headline total with the small-employer breakdown, this page uses the internally consistent detailed-profile total when an exact count is required and “about 36.2 million” in summary text.
Display and status rules
Employee values are official observed counts. Chart labels divide raw employment by 1,000 or 1,000,000 only for display. The payroll label converts the official thousand-dollar source unit to trillions of dollars. No missing industry value is estimated and no 2026 projection is produced.
Agriculture coverage: the SUSB sector row labeled Agriculture, Forestry, Fishing and Hunting does not represent all U.S. agricultural employment. Crop and Animal Production, NAICS 111 and 112, are outside SUSB coverage.
Inclusion rule: all 20 sector categories reported in the national SBA/SUSB employment table are retained. No row is added from another dataset. There are no calculated_value or modeled_projection rows, so no interpolation, CAGR, forecast formula or projection assumption is used.
This ranking does not measure worker wages, labor productivity, profits, business survival, self-employment income, output per employee, GDP by industry, market share or the number of nonemployer businesses in each sector.
Full ranking: small-business employment by SUSB sector
The table contains all 20 sector categories in the national 2022 SBA/SUSB employment table within SUSB coverage. Every row uses the same source year, unit and small-firm threshold.

What stands out in the industry data
Key insight
Health Care and Social Assistance ranks first by absolute small-business employment, with 9.26 million employees at firms below the 500-employee threshold.
Notable pattern
Accommodation and Food Services combines the second-largest small-business workforce, 8.66 million employees, with a 62.8% small-firm share of covered industry employment.
Small-firm concentration
Construction ranks third by absolute small-business employment and has 80.7% of its covered SUSB employment at firms with fewer than 500 employees.
Outlier
Other Services ranks seventh by employee count but has an 85.0% small-firm employment share, substantially higher than several sectors with larger absolute workforces.
What these figures mean for the U.S. economy
Small employer firms account for a large share of U.S. private-sector employment: 62.3 million workers, or 45.9% of employment in the 2022 SUSB universe. Their importance varies by sector, from industries where small firms employ most covered workers to sectors dominated more heavily by larger firms.
The business-count figure should not be interpreted as an employment share. Most small businesses are nonemployers, so a firm can count as a business without contributing an employee to SUSB employer statistics.
The 43.5% GDP statistic should be read as a historical structural benchmark. It is the latest dedicated SBA small-business GDP estimate identified in the cited research series, but its underlying year is 2014. It does not establish that small businesses generated exactly 43.5% of U.S. GDP in 2025 or 2026.

How many people work for small businesses in the United States?
Firms with fewer than 500 employees employed 62,250,556 people in the 2022 SUSB data, equal to 45.9% of covered private-sector employment.
How much do small businesses contribute to U.S. GDP?
The latest dedicated SBA small-business GDP study measured $5.9 trillion, or 43.5% of private nonfarm nominal GDP, in 2014. That value is a historical benchmark rather than a measured 2026 GDP share.
How many small businesses are there in the United States?
The detailed 2025 SBA national profile reports 36,186,089 small businesses using 2022 Census data: 29,811,495 nonemployer firms and 6,374,594 small employer firms. The SBA's February 2026 FAQ gives a slightly different headline total of 36,207,130 but does not reconcile that figure with its separate employer and large-business counts, so this page uses about 36.2 million in summary text.
Why can small businesses represent almost all firms but less than half of employment?
Most small businesses are nonemployer firms with no paid employees. Employer firms can also differ enormously in size, so the share of businesses and the share of workers measure different things.
Which industry has the most small-business employees?
Health Care and Social Assistance ranks first in the 2022 SUSB sector table with 9,260,938 employees at firms with fewer than 500 employees.
Does SUSB cover every U.S. worker and industry?
No. SUSB covers establishments with paid employees in most NAICS industries but excludes self-employed individuals, nonemployer businesses, most government employment and specified industries such as Crop and Animal Production, Rail Transportation, Postal Service, Private Households and Public Administration.
What does “small business” mean in this article?
The Office of Advocacy generally uses fewer than 500 employees for research. SBA program and federal contracting eligibility can use different industry-specific employee or receipts thresholds, so this research definition is not a universal eligibility rule.
Are the industry values projections for 2026?
No. Every ranking row is an official observed SUSB value for 2022. No CAGR, interpolation or projection is used to create a 2026 industry employee count.
