What changed for 2026

Texas redrew its congressional map in 2025. For District 10 that means:

309 precincts → 301 (-8)
13 counties → 13 — the county organizations this district works with.

No longer in this district:

Austin County — held 15 precincts here in 2024
Colorado County — held 11 precincts here in 2024
Fayette County — held 12 precincts here in 2024
Waller County — held 20 precincts here in 2024
Washington County — held 19 precincts here in 2024
Williamson County — held 17 precincts here in 2024

New to this district:

Houston County — 21 precincts
Leon County — 14 precincts
Polk County — 22 precincts
San Jacinto County — 11 precincts
Trinity County — 20 precincts
Walker County — 12 precincts

Still here, but a different share:

Brazos County — 113 precincts → 77 (-36)
Travis County — 44 precincts → 78 (+34)
Bastrop County — 13 precincts → 1 (-12)

A county can stay in the district while the number of its precincts here changes substantially — which a simple list of counties would not show.

Most precincts kept their exact 2024 boundaries even where the district changed — the State House, Senate and Board of Education maps were not redrawn, so this is the congressional redraw rather than counties renumbering precincts. How this was measured.
