Share of workers represented by a union ranges from 3.2% in South Carolina to 24.7% in New York: Union density of the 50 U.S. states plus D.C., in descending order and grouped into high-, medium-, and low-union-density states
|High union density||Medium union density||Low union density|
Notes: Union density is defined as the share of workers in the state who are represented by a union, including union members and other workers who are covered by a union contract, based on the variable “union” from EPI extracts of CPS-ORG microdata.
Union density is defined as the share of workers in the state who are represented by a union, including union members and other workers who are covered by a union contract, based on the variable “union” from EPI extracts of CPS-ORG microdata. We average union density data across 2015 to 2019 for each state to give a more accurate estimate of states’ typical unionization rates over time. We do not include data beyond 2019 in our averages, to avoid any potential distortions related to the 2020–2021 COVID-19 pandemic and ensuing recession.
