The Role of Small Businesses in the US Economy

Often, small businesses have been referred to as the backbone of the American economy. According to the Organisation for Economic Co-operation and Development (OECD, 2026), the U.S. Small Business Administration (SBA) generally considers a business with fewer than 500 employees to be small. The exact size standards, however, vary by industry. Small enterprises employ millions of people, create jobs and bring fresh ideas to the market. This essay will highlight the part played by small businesses in creating employment opportunities, the role that small businesses play in creating new business formations and the financial limitations that prevent small businesses from growing further.

The most critical contribution of small businesses to the US economy is in employment. According to the U.S. Small Business Administration Office of Advocacy, there are approximately 36.2 million small businesses operating in the U.S. that employ 62.3 million employees (USAFacts Team, 2025). This makes up nearly 46% of private sector jobs as shown in Figure 1. In real terms, almost half of all private sector employees receive a salary from a small business. Between March 2023 and March 2024, small firms contributed approximately 1.2 million of the 1.4 million net new jobs, or 88.9% (U.S. Small Business Administration Office of Advocacy, 2025). These statistics indicate that small businesses are not an insignificant segment of the economy. When small firms hire, the national labour market grows, and when they struggle, the effects spread quickly through communities that depend on them for work. This explains why a healthy economy needs a constant flow of new businesses even when most of them will not last.

Small businesses are also the primary source of innovation as they enable new competitors to enter markets. According to U.S. Census Bureau data reported by Founder Reports (2026), there were 5,671,836 total business applications in 2025, a new record that beat the 2023 figure. However, not all of them turn into employers. The Census Bureau classified 1,708,842 of all the applications as high-propensity, meaning that they were more likely than other applications to become businesses with a payroll (Founder Reports, 2026). The difference between applications and formations is due partly to the fact that there is a lot of entrepreneurial aspiration, but it is also hard to convert an idea into a running business. Despite this, the consistent stream of start-ups puts pressure on established firms to innovate and offer consumers more competitive products and prices. It also provides people with an alternative to traditional jobs. An entrepreneur who does not have an appropriate employment opportunity or desires greater autonomy in their work can develop an enterprise and thereby provide employment for others.

However, small businesses are constrained in their contribution largely due to a variety of factors. The Small Business Credit Survey conducted by the Federal Reserve Banks collects the evidence directly from the owners. The 2025 survey involved 6,525 small businesses and revealed that firms experienced challenges in sales growth and increased costs over the last year (Federal Reserve Banks, 2026). One way companies attempt to control those pressures is through financing, and the report shows that 60% of firms applied for financing in the 12 months before the survey, while 38% applied for a loan, line of credit, or merchant cash advance. The type of lender mattered too. Based on the information from Federal Reserve Banks (2026), applicants at small banks were more likely to be fully approved (57%) than applicants at other lenders. Therefore, it can be concluded that relationship-oriented community lenders play an important role in financing small firms. It also indicates that credit is still inequitable. When sales slow down and costs are increasing, a business without borrowing options may have to reduce hours, postpone hiring, or close. Besides this, Fairlie et al. (2023) analysed businesses closing permanently during the COVID-19 outbreak based on the use of confidential administrative data on all businesses that pay sales tax in California. According to their findings, closure rates in the first and second quarters of the COVID-19 outbreak were substantially higher among small businesses compared to large businesses. As a result, small business losses resulted in changes in market structure since market shares became more concentrated among larger businesses. This is evidence that small firms are fragile in a severe downturn and that their losses can reduce competition across markets.

As they are both important and fragile, efforts have been made by the government to assist small businesses. The most prominent among them recently has been the Paycheck Protection Program (PPP), which has been designed as an assistance program for small businesses in response to the COVID-19 pandemic (Granja et al., 2022). Granja et al. (2022) studied the program using loan-level data on all PPP loans and high-frequency administrative employment data. They found that banks played an important role in deciding which firms received the loans, which helps explain why some of the money initially flowed to regions where the pandemic damage was not as severe as in other parts. Many firms also used the loans to make non-payroll fixed payments and to build up savings buffers (Granja et al., 2022).

In conclusion, small businesses play a vital role in the U.S. economy. They represent the bulk of companies, provide almost half of private sector jobs, and generated most of the net new jobs between March 2023 and March 2024. They ensure markets remain competitive by continually introducing new competitors, despite the fact that many applications never turn into jobs. They also struggle consistently with expenses, revenue and financing. Therefore, helping small businesses is not just about helping individual owners; it is about helping the economy in which we all live, as it relies on employment and innovation.
