Middle market companies are leading job growth, employing more than 50 million people and making a contribution of nearly $6.2 trillion to the U.S. economy, according to the inaugural Middle Market Power Index from American Express and Dun & Bradstreet. Using Dun & Bradstreet’s proprietary databases of commercially active U.S. firms, the report analyzes the characteristics and economic impact of middle market enterprises—defined as businesses generating between $10 million and $1 billion in revenues.

This first in a series of Middle Market Power Index reports from American Express and Dun & Bradstreet analyzes the state of middle market companies and finds that while these companies comprise less than 1% of U.S. businesses, they make an outsized economic contribution across industries. Slightly more than one in five dollars (21%) of U.S. business revenues come from the middle market, and these firms employ over one in four workers (28%) in the private sector. Middle market companies have led job growth since 2008, with a 4.4% increase in private sector employment—outperforming both smaller businesses (less than $10 million in revenues) and the largest companies (more than $1 billion in revenues). While small firms employ the largest share of the country’s workforce, the report finds the middle market created 2.1 million (92%) of the nearly 2.3 million net new jobs added during the past seven years.

“Our first-ever look at the economic characteristics of middle market firms underscores their clout and the significance of their contribution to our economy,” said Susan Sobbott, president, Global Corporate Payments, American Express. “Since 2008, middle market companies have been the unsung heroes of employment growth.”

Characteristics of Middle Market Firms

While the majority of large firms are publicly-traded (57%), nearly 98% of middle market enterprises are privately-owned. On average, middle market businesses employ 368 workers and generate $45.1 million per firm per year, compared to 23,226 employees and $7.7 billion among larger enterprises and an average of 4 employees and nearly $276,000 among small companies.

Middle Market Firms by Industry

The report also finds that middle market firms operate in all industries, with the largest concentration in the service sector (34%). Within the service sector, business services (12%) lead among middle market companies, followed by educational services (8%) and health services (7%). Looking beyond the service sector, the data finds the next largest industries for middle market firms are wholesale or retail trade (25%), manufacturing (17%), and construction (8%). Compared to small or large enterprises, more middle market firms are concentrated in wholesale trade.

Women own 7% of commercially-active, privately-owned small businesses, 6% of middle market companies, and just 1% of large enterprises. Additionally, 2% of commercially-active small businesses are minority-owned, as are 5% of middle market companies and 1% of large firms.
