UNION MEMBERS -- 2021   

News Release from BLS, January 20, 2022

In 2021, the number of wage and salary workers belonging to unions continued to decline (-241,000) to 14.0 million, and the percent who were members of unions--the union membership rate--was 10.3 percent, the U.S. Bureau of Labor Statistics reported today. The rate is down from 10.8 percent in 2020--when the rate increased due to a disproportionately large decline in the total number of nonunion workers compared with the decline in the number of union members.

The 2021 unionization rate is the same as the 2019 rate of 10.3 percent. In 1983, the first year for which comparable union data are available, the union membership rate was 20.1 percent and there were 17.7 million union workers.

These data on union membership are collected as part of the Current Population Survey (CPS), a monthly sample survey of about 60,000 eligible households that obtains information on employment and unemployment among the nation's civilian non-institutional population age 16 and over. For further information, see the Technical Note in this news release. 

Highlights from the 2021 data:

 --The union membership rate of public-sector workers (33.9 percent) continued to be more than five times higher than the rate of private-sector workers (6.1 percent). (See table 3.)

 --The highest unionization rates were among workers in education, training, and library occupations (34.6 percent) and protective service occupations (33.3 percent). (See table 3.)

 --Men continued to have a higher union membership rate (10.6 percent) than women (9.9 percent).  The gap between union membership rates for men and women has narrowed considerably since 1983 (the earliest year for which comparable data are available), when rates for men and women were 24.7 percent and 14.6 percent, respectively. (See table 1.)

 --Black workers remained more likely to be union members than White, Asian, or Hispanic workers.   (See table 1.)

 --Nonunion workers had median weekly earnings that were 83 percent of earnings for workers who were union members ($975 versus $1,169). (The comparisons of earnings in this news release are  on a broad level and do not control for many factors that can be important in explaining  earnings differences.) (See table 2.)

 --Among states, Hawaii and New York continued to have the highest union membership rates (22.4 percent and 22.2 percent, respectively), while South Carolina and North Carolina continued to have the lowest (1.7 percent and 2.6 percent, respectively). (See table 5.)

Industry and Occupation of Union Members

In 2021, 7.0 million employees in the public sector belonged to unions, the same as in the private sector. (See table 3.)

Union membership decreased by 191,000 over the year in the public sector. The public-sector union membership rate declined by 0.9 percentage point in 2021 to 33.9 percent, following an increase of 1.2 percentage points in 2020. In 2021, the union membership rate continued to be highest in local government (40.2 percent), which employs many workers in heavily unionized occupations, such as police officers, firefighters, and teachers.

The number of union workers employed in the private sector changed little over the year. However, the number of private-sector nonunion workers increased in 2021. The private-sector unionization rate declined by 0.2 percentage point in 2021 to 6.1 percent, slightly lower than its 2019 rate of 6.2 percent. Industries with high unionization rates included utilities (19.7 percent), motion pictures and sound recording industries (17.3 percent), and transportation and warehousing (14.7 percent). Low unionization rates occurred in finance (1.2 percent), professional and technical services (1.2 percent), food services and drinking places (1.2 percent), and insurance (1.5 percent).

Among occupational groups, the highest unionization rates in 2021 were in education, training, and library occupations (34.6 percent) and protective service occupations (33.3 percent). Unionization rates were lowest in food preparation and serving related occupations (3.1 percent); sales and related occupations (3.3 percent); computer and mathematical occupations (3.7 percent); personal care and service occupations (3.9 percent); and farming, fishing, and forestry occupations (4.0 percent).

Selected Characteristics of Union Members

In 2021, the number of men who were union members, at 7.5 million, changed little, while the number of women who were union members declined by 182,000 to 6.5 million. The unionization rate for men decreased by 0.4 percentage point over the year to 10.6 percent. In 2021, women's union membership rate declined by 0.6 percentage point to 9.9  percent. The 2021 decreases in union membership rates for men and women reflect increases in the total number of nonunion workers.

The rate for men is below the 2019 rate (10.8 percent), while the rate for women is above the 2019 rate (9.7 percent). (See table 1.)

Among major race and ethnicity groups, Black workers continued to have a higher union membership rate in 2021 (11.5 percent) than White workers (10.3 percent), Asian workers (7.7 percent), and Hispanic workers (9.0 percent). The union membership rate declined by 0.4 percentage point for White workers, by 0.8 percentage point for Black workers, by 1.2 percentage points for Asian workers, and by 0.8 percentage point for Hispanic workers. The 2021 rates for Whites, Blacks, and Hispanics are little or no different from 2019, while the rate for Asians is lower.

By age, workers ages 45 to 54 had the highest union membership rate in 2021, at 13.1 percent.

Younger workers--those ages 16 to 24--had the lowest union membership rate, at 4.2 percent.

In 2021, the union membership rate for full-time workers (11.1 percent) continued to be considerably higher than that for part-time workers (6.1 percent).

Union Representation

In 2021, 15.8 million wage and salary workers were represented by a union, 137,000 less than in 2020. The percentage of workers represented by a union was 11.6 percent, down by 0.5 percentage point from 2020 but the same as in 2019. Workers represented by a union include both union members (14.0 million) and workers who report no union affiliation but whose jobs are covered by a union contract (1.8 million). (See table 1.)

Earnings 

Among full-time wage and salary workers, union members had median usual weekly earnings of $1,169 in 2021, while those who were not union members had median weekly earnings of $975. In addition to coverage by a collective bargaining agreement, these earnings differences reflect a variety of influences, including variations in the distributions of union members and nonunion employees by occupation, industry, age, firm size, or geographic region. (See tables 2 and 4.)

Union Membership by State

In 2021, 30 states and the District of Columbia had union membership rates below that of the U.S. average, 10.3 percent, while 20 states had rates above it. All states in both the East South Central and West South Central divisions had union membership rates below the national average, while all states in both the Middle Atlantic and Pacific divisions had rates above it. (See table 5.)

Ten states had union membership rates below 5.0 percent in 2021. South Carolina had the lowest rate (1.7 percent), followed by North Carolina (2.6 percent) and Utah (3.5 percent). Two states had union membership rates over 20.0 percent in 2021: Hawaii (22.4 percent) and New York (22.2 percent).

In 2021, about 30 percent of the 14.0 million union members lived in just two states (California at 2.5 million and New York at 1.7 million). However, these states accounted for about 17 percent of wage and salary employment nationally.
