Using the data

Data Format

In the current iteration, data summaries are available for contested statewide and federal elections within each county in the United States. Almost all counties are included, except for a small number of extremely small counties with too few precincts or voting districts to produce estimates.

In the summary files, each observation is identified by county, race, and cand.

  • county: County name
  • race: voter race
    • white: White
    • black: Black
    • hisp: Hispanic
    • oth: Other race or ethnicity (not White, Black, or Hispanic)
  • cand: candidate
  • mean: mean estimate of support
  • sd: standard deviation of the estimate
  • ci_95_lower: lower bound for the 95% confidence interval
  • ci_95_upper: upper bound for the 95% confidence interval
