Candidate Characteristics Cooperative (C3) 2018 Data

The Candidate Characteristics Cooperative (C3) 2018 Data is the result of a collaborative, hand-coded effort to code the race/ethnicity and gender of state legislative primary and general election candidates from 2018. Covering approximately 14,500 unique major-party and minor-party candidates, contributors were able to identify the race/ethnicity of 94% of the candidates. The C3 2018 dataset also has similarly complete coding of candidate gender. The data are useful for those studying legislative representation and elections in the United States.
