Former president Donald J. Trump won the Iowa caucuses on Monday, with The Associated Press calling the race for Mr. Trump less than an hour after caucusing began. The state Republican party reported precinct-level results, the most detailed vote data available for the first 2024 presidential election contest.
The map above shows the leading candidate in each precinct. It is shaded according to the number of votes per square mile for that candidate, meaning sparsely populated areas where fewer caucusgoers live are lighter, and denser areas are darker.

Here’s another way to look at the results for the top three candidates — Mr. Trump, Gov. Ron DeSantis of Florida and Nikki Haley, the former South Carolina governor. The maps below show precincts shaded according to each candidate’s share of the vote.

Methodology
Higher income areas are precincts where the median household income is $100,000 or more; lower income areas are where the median household income is less than $50,000. Areas with more college graduates are precincts where more than 40 percent of the population has a college education; areas with fewer college graduates are precincts where less than 15 percent of the population graduated college. The classification of areas as urban, rural or suburban is derived from research by Jed Kolko.
Chris Christie dropped out of the presidential race last week, but the Iowa Republican Party will still tabulate any votes he receives in the caucuses.
