Texas redrew its congressional map in 2025. For District 20 that means:
- 247 precincts → 299 (+52)
- 1 county → 1 — the county organizations this district works with.
Still here, but a different share:
- Bexar County — 247 precincts → 299 (+52)
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.
