Small business health is key to U.S. growth – half of American jobs and 99% of U.S. firms – worth trillions

Most U.S. adults (86%) say small businesses have a positive effect on the way things are going in the country these days, according to a recent Pew Research Center survey. Small businesses, in fact, receive by far the most positive reviews of any of the nine U.S. institutions we asked about, outranking even the military and churches.

Despite their name, small businesses loom large in the United States. These businesses – defined here as those with 500 employees or fewer – account for 99.9% of U.S. firms, according to the Small Business Administration. While most of these 33 million firms don’t have paid employees, about 6 million of them do. They account for just under half of total private sector employment (46%).

As National Small Business Week approaches, here’s a look at small businesses in the U.S. and public attitudes about them, based on federal data and Center surveys.

Just how ‘small’ are small businesses?

Among the roughly 6 million small businesses with employees, 49% have just one to four workers, according to the latest estimates for 2021 from the Census Bureau’s Annual Business Survey (ABS). About a quarter (27%) have between five and 19 employees; 8% have 20 to 99; and just 1% have 100 to 499 workers. The remaining 14% had paid employees at some point during the year, but not during the March 12 pay period, which the ABS uses to determine employment size.

Overall, small businesses employed an estimated 56.4 million workers in 2021 and brought in over $16.2 trillion in revenue, according to ABS data. Perhaps unsurprisingly, small businesses with more employees tend to account for larger shares of overall revenue than those with fewer workers.
