Generally speaking, the private sector is made up of privately and publicly owned businesses. Giant corporations such as Walmart, McDonald’s, and Apple are all examples of publicly owned, private-sector businesses. One of their sources of funding is issuing stocks that are bought on a public stock exchange by investors; this makes them publicly owned. Smaller businesses, like your neighborhood barbershop or self-employed people, are privately owned private-sector businesses. They do not issue stocks to investors, so they remain privately owned. Small businesses are the most commonly owned type in the U.S. Some structures used by these businesses include corporations, cooperatives, trusts, partnerships, and sole proprietorships.

How the Private Sector Works

When someone wants to start a private-sector business in the U.S., they generally have three options: self-funding, finding investors, or obtaining business loans. As a company grows, it may choose to finance its growth by making an initial public offering (IPO). That means the company issues stock that becomes available for the general public to buy and sell on stock exchanges. Privately owned businesses that don’t issue public stocks tend to be smaller, often family-owned or owned by a small group of people.

Private Sector vs. Public Sector

In free-market capitalist societies, the private sector tends to occupy a much larger role than the public sector. According to the Brookings Institute, in 2020, the public sector made up about 15% of the workforce in the U.S., while the public sector in Russia employed close to 40% of the workforce. The private and public sectors frequently intersect. While individuals and businesses control the private sector, they typically need licenses and permits from government agencies to operate. The public sector also regulates businesses and provides the infrastructure, such as highways and bridges, that businesses need to operate. Traditionally, working in the public sector has been viewed as more stable than private-sector employment. Employee tenure tends to be shorter in the private sector compared to the public sector. In 2020, public-sector employees had an average tenure of more than six years, nearly double that of public-sector employees, whose average tenure was more than three years. Public-sector workers also participated in unions at about five times the rate of private-sector workers in 2020. Comparing compensation between the sectors is difficult because of the types of jobs available in each sector. For example, manufacturing and sales make up a significant portion of private-sector activity. However, these roles are rare in the public sector. About two-thirds of state and local government employees work in administrative support and professional occupations, including teachers. In the private sector in 2020, these roles accounted only for about half of the jobs. In a 20-year study of wages, the National Institute on Retirement Security found that state and local government workers earned about 11% to 12% less than their private-sector counterparts, although the public-sector workers had slightly more benefits. A Congressional Budget Office (CBO) report found that between 2011 and 2015, federal workers with lower levels of education earned more than private-industry workers in similar positions. However, federal workers with a doctoral or professional degree earned 34% less than their public-sector counterparts.
