Update, November 22: The finalized county precinct data has been incorporated into the map above; a layer showing voter turnout has been added as well.

With all 1,012 precincts shaded in by civic data whiz Jeff Reichman, the interactive map above of last week’s election results shows both stark splits and gray areas in blue-swung Harris County, which gave only 41.8 percent of its vote to Wrestlemania hall-of-famer and historically litigious president-elect Donald Trump. The red-to-blue shading shows who won by what percentage, with results ranging from count-’em-on-one-hand margins to total blowouts for one major candidate or the other. You can click on each precinct to see the breakdown of votes and turnout (though Stein, Johnson, and McMullin voters will have to look elsewhere for the details on those candidates’ spreads).

On the east side of town, the red-blue divide runs roughly along the track of Beltway 8; the border of that central dark blue zone stretches north to include Greenspoint and then runs east along FM 1960 to 290. The split gets murkier on the west side of the Inner and Outer Loops, with many precincts showing much closer margins. More noticeably red areas inside Beltway 8 show up near Memorial, River Oaks, Bellaire, and Shepherd Park Plaza — plus spots like tiny Precinct 0830 on S. Main, where Trump took a total of 3 votes to Clinton’s 1.
