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. 

Source: EPI analysis of 2023–2025 Current Population Survey Outgoing Rotation Group (CPS-ORG) microdata for all workers ages 16 and older.
