## Small Business: Driving America's Growth

1. How do small businesses contribute to the U.S. economy?
Although large corporations dominated the business scene for many decades, in recent years small businesses have once again come to the forefront. Downsizings that accompany economic downturns have caused many people to look toward smaller companies for employment, and they have plenty to choose from. Small businesses play an important role in the U.S. economy, representing about half of U.S. economic output, employing about half the private sector workforce, and giving individuals from all walks of life a chance to succeed.

### What Is a Small Business?

How many small businesses are there in the United States? Estimates range from 5 million to over 22 million, depending on the size limits government agencies and other groups use to define a small business or the number of businesses with or without employees. The Small Business Administration (SBA) established size standards to define whether a business entity is small and therefore eligible for government programs and preferences that are reserved for “small businesses.” Size standards are based on the types of economic activity or industry, generally matched to the North American Industry Classification System (NAICS).
Small businesses are defined in many ways. Statistics for small businesses vary based on criteria such as new/start-up businesses, the number of employees, total revenue, length of time in business, nonemployees, businesses with employees, geographic location, and so on. Due to the complexity and need for consistent statistics and reporting for small businesses, several organizations are now working together to combine comprehensive data sources to get a clear and accurate picture of small businesses in the United States.  provides a more detailed look at small-business owners.
One of the best sources to track U.S. entrepreneurial growth activity is the Ewing Marion Kauffman Foundation. The Kauffman Foundation is among the largest private foundations in the country, with an asset base of approximately $2 billion, and focuses on projects that encourage entrepreneurship and support education through grants and research activities. They distributed over $17 million in grants in 2013.
The Kauffman Foundation supports new business creation in the United States through two research programs. The annual Kauffman Index of Entrepreneurship series measures and interprets indicators of U.S. entrepreneurial activity at the national, state, and metropolitan level. The foundation also contributes to the cost of the Annual Survey of Entrepreneurs (ASE), which is a public–private partnership between the foundation, the U.S. Census Bureau, and the Minority Business Development Agency. The ASE provides annual data on select economic and demographic characteristics of employer businesses and their owners by gender, ethnicity, race, and veteran status. The Kauffman Index of Entrepreneurship series is an umbrella of annual reports that measures how people and businesses contribute to America’s overall economy. What is unique about the Kauffman reports is that the indexes don’t focus on only inputs (as most small-business reporting has been done in the past); it reports primarily on entrepreneurial outputs—the actual results of entrepreneurial activity, such as new companies, business density, and growth rates. The reports also include comprehensive, interactive data visualizations that enable users to slice and dice a myriad of data nationally, at the state level, and for the 40 largest metropolitan areas.
The Kauffman Index series consists of three in-depth studies—Start-up Activity, Main Street Entrepreneurship, and Growth Entrepreneurship.
1. The Kauffman Index of Startup Activity is an early indicator of new entrepreneurship in the United States. It focuses on new business creation activity and people engaging in business start-up activity, using three components: the rate of new entrepreneurs, the opportunity share of new entrepreneurs, and start-up density.
2. The Kauffman Index of Main Street Entrepreneurship measures established small-business activity—focusing on U.S. businesses more than five years old with less than 50 employees from 1997 to 2016. Established in 2015, it takes into account three components of local, small-business activity: the rate of businesses owners in the economy, the five-year survival rate of businesses, and the established small-business density.
3. The Kauffman Growth Entrepreneurship Index is a composite measure of entrepreneurial business growth in the United States that captures growth entrepreneurship in all industries and measures business growth from both revenue and job perspectives. Established in 2016, it includes three component measures of business growth: rate of start-up growth, share of scale-ups, and high-growth company density.
Data sources for the Kauffman Index calculations are based on Current Population Survey (CPS), with sample sizes of more than 900,000 observations, and the Business Dynamics Statistics (BDS), which covers approximately 5 million businesses. The Growth Entrepreneurship Index also includes Inc. 500/5000 data).
Small businesses in the United States can be found in almost every industry, including services, retail, construction, wholesale, manufacturing, finance and insurance, agriculture and mining, transportation, and warehousing. Established small businesses are defined as companies that have been in business at least five years and employ at least one, but less than 50, employees.  provides the number of employees by the size of established business. More than half of small businesses have between one and four employees.

### Summary of Learning Outcomes

1. How do small businesses contribute to the U.S. economy?
Small businesses play an important role in the economy. They account for over 99 percent of all employer firms and produce about half of U.S. economic output. Most new private-sector jobs created in the United States over the past decade were in small firms. The Small Business Administration defines a small business as independently owned and operated, with a local base of operations, and not dominant in its field. It also defines small business by size, according to its industry. Small businesses are found in every field, but they dominate the service, construction, wholesale, and retail categories.
