Notes: Union density is defined as the share of workers in the state who are members of a union based on the variable “unmem” from EPI extracts of CPS-ORG microdata.
Union density is defined as the share of workers in the state who are members of a union based on the variable “union” from EPI extracts of CPS-ORG microdata. We average union density data across 2023 to 2025 for each state to give a more accurate estimate of states’ typical unionization rates over time.
