In 2020, NCSL conducted new research on state legislator demographics, not only to learn who voters elect, but also who NCSL serves and what has changed about the organization's members since its last demographic research was conducted in 2015. The 2020 data does not include legislators who were newly elected in 2020 and took office in 2021.
Data for 2015 and 2020 is shown below in the following categories: gender, race/ethnicity, generation*, party, religion and highest level of education.
Please note that data for many of the states and categories is not complete (see the “no data” rows). Consequently, any conclusions drawn from this data must contend with those limitations. Also, due to rounding, the totals sometimes add up to greater or less than 100%.
