U.S. election results — FAQ
What presidential election data is available by county?+
Certified vote totals, two-party share, margin and cycle-over-cycle swing for 3,113 counties across 13 presidential elections, 2000 through 2024. County returns are as certified by state election authorities and compiled by the MIT Election Data and Science Lab.
Does winning a county's popular vote mean winning the election there?+
No, and conflating the two is the most common error with county-level returns. Presidential electors are awarded at the state level (except in Maine and Nebraska, which award some by congressional district), so a county's popular-vote winner carries no electoral weight of its own. A candidate can carry most of a state's counties and still lose the state.
Why do county boundaries make some comparisons difficult?+
Several states report presidential results on units that are not ordinary counties — Alaska reports by district rather than borough, and some New England states report by town. County boundaries and reporting units have also changed over the period covered, so a long series for one place is not always a series for the same geography.
Where does this data come from?+
County-level presidential returns come from the MIT Election Data and Science Lab, which compiles certified results from state election authorities. pumsdata is independent and not affiliated with MEDSL, with any campaign or party, or with any election authority.
