10 States With the Strongest Unions

Editor's Note: This story originally appeared on SmartAsset.com.

The U.S. Bureau of Labor Statistics says that roughly 1 out of 10 workers in 2020 were union members (10.8%). Membership has gone up 0.5% since 2019, but has decreased by more than half since 1983, when approximately 1 out of 5 workers were union members (20.1%). Historically, organized labor has played an influential role in the U.S. workforce, establishing and defending employee rights since the first union was founded by Philadelphia shoemakers in 1794. Keeping this in mind, SmartAsset crunched the numbers to see where unions are strongest nationwide.

To do this, we considered seven metrics: percentage of workers who are union members, the four-year change in union membership, average annual wage for all workers, average annual wage for middle school teachers, salary ratio of teachers to all occupations, average annual wage for firefighters and the salary ratio for firefighters to all occupations. We looked specifically at teachers and firefighters because these two professions generally have the highest unionization rates, according to the BLS. For details on our data sources and how we put all the information together to create our final rankings, read the Data and Methodology section at the end.

Data and Methodology

To find the states with the strongest unions, SmartAsset considered data from 49 states (Vermont had insufficient data) across the following seven metrics:

• Percentage of workers who are union members. Data comes from UnionStats.com and is for 2020.
• Four-year change in union membership. Data comes from UnionStats.com and is for 2016 and 2020.
• Average annual wage for all occupations. Data comes from the Bureau of Labor Statistics (BLS) and is for 2020.
• Average annual wage for middle school teachers. Data comes from the BLS and is for 2020. According to the BLS, among occupational groups, one of the highest unionization rates in 2020 was in education, training and library occupations. Middle school teacher is a prominent occupation within that industry. Workers in this job tend to make middle-range salaries for all occupations within the industry.
• Salary ratio for teachers to all occupations. Data comes from the BLS and is for 2020.
• Average annual wage for firefighters. Data comes from the BLS and is for 2020. According to the BLS, among occupational groups, one of the highest unionization rates in 2020 was in protective service occupations. Firefighter is a prominent occupation within that industry. Workers in this job tend to make middle-range salaries for all occupations within the industry.
• Salary ratio for firefighters to all occupations. Data comes from the BLS and is for 2020.

First, we ranked each state in each metric. We then found the average ranking for each state, giving a double weight to the two metrics regarding union membership — the percentage of workers in unions and four-year change in union membership — and a half weight to the four metrics regarding average annual wages and salary ratios for teachers and firefighters. We then used the average rankings to create our final rankings. The state with the highest average ranking received a score of 100, and the state with the lowest average ranking received a score of 0.
