Fort Bend County's rapid demographic transformation — driven by South Asian and African American population growth in cities like Sugar Land — has compressed a once-wide Republican margin to near-parity in presidential contests.
The county's recent history is a story of close margins. The Democratic margin reached ninety-one points in 1932; the Republican margin reached thirty-nine points in 1972. Most other elections have been decided by single-digit points.
Fort Bend County's demographics — a population of 893,767, a 34% non-Hispanic-white share, a median household income of $114,041 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Gwinnett County and Orange County.
