Some interestingfindings 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.
