Each row is a county-allocated estimate of U.S. House votes for this district — county returns apportioned onto its boundary, not precinct-counted. “Vote lead” is the estimated local lead here, not necessarily the winner of the full contest.
With a 2024 presidential margin of D+20.6 in a population of roughly 88,000, this district reflects the heavily urbanized, high-density character of Northern Virginia corridors where college-educated and immigrant households have reshaped the electorate over two decades.

A population of 87,808, a 42% non-Hispanic-white share, and a median household income of $78,793 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 113 and State House District 162.
