What percentage of America is small business

Quick answer and what this article covers

Short headline answers by metric

There is no single answer to “what percentage of America is small business.” Which percent matters depends on whether you mean how many business entities exist, how many workers are employed by small firms, or how much of U.S. output small firms produce. For a quick headline: by the federal fewer-than-500-employees rule about 99.9 percent of firms are classified small, small firms employ roughly 45 to 47 percent of private-sector workers, and under one SBA method small firms are estimated to produce roughly 40 to 45 percent of U.S. GDP SBA small-business profile.

How to use this guide

This guide explains the definitions behind each metric, points to the public tables to confirm the numbers, warns about common mistakes, and gives scenario-based advice on which percent to cite for typical questions. Read the short answers first, then follow the sections that match your purpose.

Definitions and context: what ‘small business’ can mean

The federal definition commonly used in high-level summaries classifies most firms as small when they have fewer than 500 employees; that threshold is applied in SBA profiles and summary tables and drives the very large firm-count percentage in many headlines SBA small-business profile.

Census statistics treat business entities and nonemployer firms differently. The Statistics of U.S. Businesses and Nonemployer Statistics record employer firms, nonemployer firms, and counts by size class; those table choices change headline totals and therefore which percent is most meaningful Statistics of U.S. Businesses (SUSB).

When analysts report a small-business share of GDP they combine BEA industry output with firm-size distributions or use a decomposition method. That approach requires choices about value-added allocation and industry mapping, so a GDP-share number is necessarily method dependent and should be presented with the chosen method noted SBA small-business GDP methodology.

Measuring by firm count: why nearly all U.S. firms are ‘small’

Under the federal fewer-than-500-employees rule, the SBA reports that about 99.9 percent of U.S. firms are classified as small; this is the standard headline for firm counts and reflects the high numerical prevalence of very small and single-owner entities SBA small-business profile.

The Census SUSB reports roughly 33 million total business entities when employer and nonemployer firms are combined; including nonemployer firms-sole proprietors and other single-establishment businesses without payroll-raises the count substantially and is the reason the firm-count percent is so large Statistics of U.S. Businesses (SUSB).

Nonemployer firms are the bulk of the count. Recent nonemployer statistics show that roughly four-fifths of business entities are nonemployer firms, which means many business entities appear in counts even though they do not have payroll employees Census Nonemployer Statistics.

Measuring by employment: how many Americans work for small firms

When the question is about workers, the employment share gives the clearest answer: recent SBA and Census summaries put small firms at about 45 to 47 percent of private-sector employment, which tells you roughly how many private-sector workers are employed by firms that meet the small-business threshold used in those summaries SBA small-business profile.

Employment share is useful for policy and labor questions because it measures worker exposure to small firms rather than the raw number of firms. The measure has limits: it focuses on private-sector employment and depends on the employment cutoffs used in the source tables; researchers often cross-check with BLS business-employment datasets for flows and trends BLS Business Employment Dynamics resources.

Use employment shares when you need to know where people work, for example when assessing job creation patterns, worker exposure to small employers, or the employment implications of sector changes. To check trends, compare successive annual tables rather than a single headline percent Statistics of U.S. Businesses (SUSB).

Measuring by GDP or value added: how output-based percentages are made

SBA Office of Advocacy estimates place small businesses near 40 to 45 percent of U.S. GDP under their published methodology, but the estimate depends on industry decomposition choices and historical assumptions, so treat the figure as an approximate, method-dependent result rather than a settled share SBA small-business GDP methodology.

Researchers use BEA industry GDP tables as the underlying totals and then apply firm-size value-added shares or decomposition steps to estimate how much output small firms generate. The BEA tables provide the totals by industry that these calculations rely on BEA GDP by industry.

Because the conversion from industry totals to firm-size value added requires mapping firm distributions into industry categories, the final GDP-share number is sensitive to assumptions about how value is attributed within industries; always report the method and the BEA table you used when citing a small-firm GDP share SBA small-business GDP methodology.

For nonemployer detail, the Census Nonemployer Statistics series reports the number and basic industry distribution of sole proprietors and other single-establishment nonpayroll businesses; use those tables when you want to understand how much of the business count comes from nonemployer firms Census Nonemployer Statistics.

Choosing which percentage matters for your question

Pick the metric that matches your question: firm count for prevalence, employment share for worker exposure, and GDP share for economic output. Name the metric, the data source, and the year when you quote a percentage.

For example, cite SUSB tables for counts, the SBA or SUSB employment tables for employment shares, and SBA GDP estimates together with the BEA tables for output-based claims. The short checklist above points to the exact tables most readers need.

A frequent error is quoting the firm-count percent when the question is about workers; using 99.9 percent of firms to imply that most Americans work for small firms is misleading because counts and employment shares answer different questions SBA small-business profile.

Another mistake is failing to name the year and source. Always include the metric, the data source, and the publication year in any public citation so readers can check the underlying table and method Statistics of U.S. Businesses (SUSB).

Do this instead: state the question you mean to answer, then give the appropriate percentage and the exact table. If you are reporting a GDP-share figure, also note the decomposition method used and point to BEA industry totals as the base BEA GDP by industry.

Common mistakes and how to avoid them

Scenario 1, worker exposure. If you want to know how many workers are affected by a policy change, use the employment share. Recent SBA and Census summaries put that share near 45 to 47 percent of private-sector employment, so cite the employment table and the year to be specific USAFacts.

Scenario 2, counting entrepreneurs. If you want to count entrepreneurs or sole proprietors, use SUSB totals including nonemployer tables; the combined employer and nonemployer count is about 33 million business entities in recent SUSB reporting, and the nonemployer series shows the single-establishment firms dominate that total Statistics of U.S. Businesses (SUSB).

Scenario 3, economic contribution. If your question is about output, use a GDP-share estimate and present the method. The SBA Office of Advocacy provides an approach that yields a small-firm GDP share near 40 to 45 percent using BEA totals as the baseline, but include the method note when you cite it SBA small-business GDP methodology.

Nonemployer firms: why they dominate counts and what that implies

Nonemployer firms are businesses without payroll that often represent sole proprietors or single-establishment operations. They are counted in the Census nonemployer series and in SUSB totals when those totals include nonemployer firms Census Nonemployer Statistics.

Because nonemployer firms make up roughly four-fifths of business entities in recent reporting, including them in firm counts greatly increases the number of entities and is the main reason the firm-count percent reaches the very high values reported in headline summaries Statistics of U.S. Businesses (SUSB).

Exclude nonemployer firms when your question is about payroll employment, employer-based benefits, or measures that require payroll records; state that choice explicitly in any citation.

State and local considerations: adapting national percentages to local contexts

SUSB provides state-level breakdowns that let you compute local firm counts and employer-only totals; industry composition and nonemployer presence can change both employment and GDP shares at the state or district level, so national percentages do not always apply locally.

When comparing a district or county to the national picture, check the state or local SUSB tables, and note whether the local economy has a heavier or lighter share of industries that are typically small-firm intensive; this explains much local variation.

How journalists and researchers should cite these numbers

Required citation elements: name the metric (count, employment, or GDP), the data source, and the year. This checklist helps readers reproduce your number and judge its relevance Statistics of U.S. Businesses (SUSB).

Model sentence for counts: “According to the Census Statistics of U.S. Businesses (SUSB), including nonemployer firms, about 33 million business entities existed in year X.”

Model sentence for GDP-share statements: “Under the SBA Office of Advocacy method using BEA industry totals, small firms account for an estimated share of U.S. GDP; the estimate and method are reported by the SBA Office of Advocacy.”

Tools and resources for staying current

Primary update pages to watch are the SBA small-business profile, SUSB tables and nonemployer series, BEA GDP by-industry tables, and BLS business-employment resources. Bookmark the specific table or CSV for reproducible citation SBA small-business profile.

Validation checks: confirm metric, source, and year; check whether counts include nonemployer firms; and, for GDP claims, confirm which BEA table and decomposition method were used BEA GDP by industry.

Conclusion: best-practice takeaways

Which percentage of America is small business depends on your question. Use firm-count figures to describe prevalence, employment share to describe where people work, and GDP share to describe output; always name the metric, the data source, and the year when you report a percent SBA small-business profile.

For next steps, consult the SBA profile, SUSB tables, or BEA industry tables depending on whether you need counts, employment, or GDP detail. Present percentages with method notes so readers can check the underlying tables and assumptions.
