Want to know who voted for what? And how that breaks down along geographic and other lines? We've got you covered. APM Research Lab's fantastically nerdy new tool lets you explore who makes up California's population — eligible voters and others — in all 53 of its congressional districts. Another searchable map lets you look at the voting history in those districts.

"We hope that this project will help to keep election coverage focused on what is most important: the people who Congress is elected to represent," said Craig Helmstetter, APM Research Lab's Managing Partner.

As we head for the 2018 mid-term elections in November, look for deeper dives and savvy breakdowns into California's most hotly contested races. Have a question or spot something you want to know more about? Leave a comment below and we'll get back to you.

Some interesting findings by APM Research Lab:

  • 124 of the nation's 435 Congressional Districts "minority majority" districts, where people of color collectively outnumber non-Hispanic whites.
  • The district with the highest number of Latinos? California's 40th, which runs along both sides of the 710 Freeway and includes the cities of Huntington Park, Bell, and Commerce, and unincorporated East Los Angeles. Some 88% of residents there are identified as "Hispanic" in the latest census estimates.

That district has been represented by Lucille Roybal-Allard, a Democrat, since 1992. She was the first Mexican-American woman elected to Congress.

Roybal won her last election with nearly 72% of votes cast. Sixteen of her fellow California Democrats in the House of Representative won by wider margins.

California is also home to the two districts with the highest annual median incomes in the nation. California's 17th and 18th districts report median household incomes of $120,000, about twice the national average.

The 17th, of course, is in the heart of Silicon Valley. Democrat Ro Khanna currently is running for reelection there. And the 18th, represented by incumbent Democrat Anna Eshoo, is nearby and includes Palo Alto, Menlo Park and Google's hometown of Mountain View.
