Notes: Data refers to workers 16+. Self-employed and self-incorporated workers are excluded. 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 2019 to 2023 for each state to give a more accurate estimate of states’ typical unionization rates in recent years.
