The Most Unionized Cities in America

With the global economy in flux due to the coronavirus outbreak, worker protections have been under increased scrutiny. Massive layoffs, especially in the retail, leisure, and hospitality industries, have left millions of Americans without a steady paycheck or benefits. Unfortunately, some of the hardest hit industries also report low union membership rates, making workers even more vulnerable.

Union membership in the U.S. has declined significantly over the past several decades—a result of more states passing “right-to-work” laws and changes in the composition of the U.S. labor force. Many of the fastest-growing industries have low rates of union participation. In 1979, 24 percent of U.S. employees belonged to a union. By contrast, only 10.3 percent of American workers were union members in 2019. In nominal numbers, union membership accounted for roughly 14.6 million workers in 2019, approximately 6.5 million fewer than the 1979 peak.

Industry sectors with the highest union membership rates include government, transportation, utilities, and construction. In each of these sectors, union membership rates are above the national average of 10.3 percent. By contrast, employees who work in finance, professional services, leisure, and wholesale/retail trade are far less likely to belong to a union. Union membership in each of these industries is below 5 percent.

Differences in local economies, politics, and legislation also impact union membership rates. Coastal states such as Hawaii, New York, and Washington have the highest membership rates, at 23.4 percent, 21 percent, and 18.8 percent, respectively. Conversely, more conservative Southern states, such as North Carolina, South Carolina, Virginia, Texas, and Georgia, have membership rates below 5 percent.

To find the most unionized places in America, researchers at Construction Coverage, a review site for workers’ comp and commercial auto insurance, analyzed union membership and coverage data from the U.S. Bureau of Labor Statistics and UnionStats.com. They ranked the metropolitan areas with the highest and lowest union membership rates. In addition to union membership, the researchers also included statistics on union representation, which is the share of workers whose terms of work are collectively negotiated (whether or not they are union members).

Only metro areas with a population of 100,000 or more were included in the analysis. To improve relevance, metros were grouped into size cohorts based on population size: large metros (1,000,000 residents or more), midsize metros (350,000-999,999 residents), and small metros (less than 350,000 residents). Like the statewide trends, metros on the East and West Coast tend to have the highest union membership, while Southern metros have the least.
