The Gender Parity Index measures women's representation across the local, state legislative, state-wide executive, and federal levels and grades them according to their performance.

Our 2017 Report is the fourth in a series leading to the year 2020, the centennial of the 19th Amendment. The report finds that women are underrepresented at the national, state, and local level, and that parity for men and women in elected office is unlikely to occur without structural changes in recruitment, electoral, and legislative rules.
