How Dallas County's Precincts Changed for 2026

Every few years the voting precinct lines get redrawn, and for the people who organize them — precinct chairs, block walkers, and county party staff across Dallas County — the first question is always the same: did my precinct change, and what happened to the turf I've been working?

Dallas County is home to Dallas, along with dozens of surrounding municipalities — Irving, Garland, Mesquite, Grand Prairie, Richardson, Carrollton, DeSoto, Cedar Hill, Duncanville, Lancaster, Rowlett, and many more. We compared the county's previous precinct map against the new 2026 map and measured exactly how much of each new precinct came from each old one. Here's what we found.

At a glance: the numbers

Dallas County went from 885 to 791 voting precincts — a net loss of 94. Where Harris County to the south added precincts, Dallas consolidated: more of its precincts were merged together than split apart. But that headline number oversells the disruption:

• 81.3% of the new precincts are essentially unchanged — 643 of 791, with nearly all of their area coming from a single old precinct.
• And yet 341 precincts — 43.1% — are now in a different congressional district, against just 29.7% of the county’s territory.
• Only 3 new precincts were truly overhauled — genuine multi-way blends where no single old precinct contributes even half.
• With the same county divided into fewer pieces, the average precinct grew about 12% (2.66 → 2.97 km²).

A sanity check confirms the picture: the old and new maps each cover about 2,353 km² — Dallas County's actual area — so nothing was lost or double-counted in the redraw.

Why the change is mostly local

If you chaired a precinct before, the odds are very strong your territory is intact. The 94 fewer precincts come from consolidation: a county merging some of its smaller precincts into larger ones, not a wholesale redrawing. For the large majority of Dallas-area neighborhoods, the precinct you knew in the last cycle is the precinct you'll knock in the next one — sometimes joined to a neighbor.

The real story: a handful of genuine merges

The action is in a small set of precincts that were truly reshaped — the genuine blends, where a new precinct is stitched from pieces of several old ones. Only three precincts were overhauled badly enough that no single old precinct supplies even half their area:

• Precinct 2611 is the most blended of all: a five-way merge whose largest single source contributes just 43%.
• Precinct 2410 is a four-way blend, its biggest piece about 42% of the new precinct.
• Precinct 4004 is a near-even three-way split, roughly half from its dominant predecessor.

Most new precincts in Dallas were built from a single predecessor — the county-wide average is 1.29 old precincts per new one. The blending is real but concentrated: a minority of precincts were assembled from several, while the majority simply carried over. For precincts like the three above, “who organizes this now?” isn't automatic — it's a decision.

What happened to your old precinct?

The reverse view matters too. Because Dallas consolidated, many old precincts were folded into a larger neighbor — so a chair's former turf may now sit inside a precinct with a new number. We mapped every old precinct to where its area went, so any organizer can trace their precinct forward.

Your precinct didn’t move. Your congressman did.

Dallas County’s precincts were substantially reworked for 2026 — the county cut 94 of them, and 81.3% of what remains has its 2024 boundaries. But the change voters will actually feel came from somewhere else entirely.

341 of Dallas County’s 791 precincts — 43.1% — are now in a different congressional district.

How we can be sure which change did it

The 2025 mid-decade session redrew the congressional map and left everything else alone. The State House, State Senate and State Board of Education maps are identical to their 2024 versions.

That gives a control. If redrawing precincts pushed voters across district lines, it would push them across those lines too — they never moved, so anything crossing them is the precincts’ doing alone.

Statewide, redrawing every precinct in Texas moved 3.7 km² across a State House boundary. In Dallas County the figure is 0.00%. The congressional redraw moved 121,370 km² — about a sixth of the state. The ratio is roughly 33,000 to 1.

Two numbers, and the gap between them is the story

By territory, 29.7% of Dallas County changed congressional district — 700 of its 2,353 km². By precinct count, 43.1% did.

That 13-point gap is not a discrepancy. It means the reassigned precincts are smaller than the county average — the redraw cut through Dallas’s dense, urban ground and left more of its open land alone. Because precincts are drawn to hold roughly comparable numbers of voters, the precinct figure is the better guide to how many people were affected. In Dallas, the territory number understates it.

Not every county works this way. In Travis County the relationship inverts — 63% of the territory but 52% of the precincts — meaning the ground reassigned there was the sparser part of the county. Which number is larger tells you whether a redraw took a county’s core or its edges.

What happened in Dallas specifically

The same six congressional districts cover Dallas before and after — 5, 6, 24, 30, 32 and 33. None arrived; none left. What changed is which one a given neighborhood sits in, and the movement is concentrated:

District 33 is the large net gainer, drawing 152 precincts from Districts 30 and 32 combined.

42 Dallas precincts are “mixed origin” — assembled from predecessors that sat in two different congressional districts, so they have no single “before.” That is more than three times Harris’s dozen, and it reflects how much more Dallas reworked its precincts. They are shown as their own category on the map rather than forced into one answer.

Separately, 48 precincts kept their exact 2024 boundaries but were renumbered — same ground, new number. If your precinct number changed but nothing else looks different, that is probably you.

One thing this analysis does not show: who benefits. It uses boundary data only — no election results, no party registration — so it can say where territory moved, but not what that movement means politically. We make no partisan claim from it.

What it means for organizing

Boundaries are only half the story; the other half is people. Lining the new map up against the current Dallas County precinct-chair roster (the public Secretary of State list) tells the organizing story:

• 377 new precincts have a natural incumbent — a current chair whose 2024 territory makes up the largest part of the new precinct.
• 414 new precincts — just over half — have no obvious incumbent, because they're built mostly from precincts that sit vacant today.

That second number isn't a problem so much as a map of where to recruit. Only about 41% of Dallas's current precincts have a chair at all, so the consolidation mostly preserves who's organizing where while pointing clearly at the open ground. (Chairs are matched from the current precinct map; the 2026 precincts won't have their own elected chairs until the next cycle.)

Common questions

Did my congressional district change in Dallas County?

Possibly — 341 of Dallas County’s 791 precincts (43.1%) are in a different congressional district for 2026 than they were in 2024. Find your precinct on the map above and click it to see its before and after.

My Dallas precinct number changed but the boundaries look the same. Why?

48 Dallas precincts kept their exact 2024 boundaries and were simply renumbered. A new number on its own tells you nothing about your districts.

Why do the percentage of land and the percentage of precincts differ?

Because the precincts that changed district are smaller than average. 29.7% of Dallas County’s land changed congressional district but 43.1% of its precincts did — the redraw cut through denser ground. Precincts hold roughly comparable numbers of voters, so the precinct figure is the better guide to how many people were affected.

Does this analysis show which party benefits?

No. It uses boundary data only, with no election results and no party registration, so it can show where territory moved but not what that means politically. We make no partisan claim from it.

Have a GIS question? Ask us

We build maps and spatial analyses like this one all the time. If there's a geographic or precinct-data question you'd find useful — a comparison, a map, a neighborhood breakdown — just ask. If we can manage it, we'll likely help out. Reach us through the site, and tell us what you're trying to see.

And if something here looks wrong, or just looks interesting, please tell us. This is a genuinely complicated piece of work — two precinct maps, two congressional plans, and hundreds of thousands of intersecting pieces of ground — and the people who know a neighborhood are usually the first to spot something the data got wrong. If a precinct looks off, if a number does not match what you know, or if you would simply like something on this page explained, drop us a line through the contact form. We read every one, and corrections are welcome.

Sources and method

Precinct boundaries are the Texas Legislative Council’s published files: Precincts24G (9,657 precincts, 2024 general) and Precincts26P (9,614 precincts, published 15 July 2026). District assignments come from TLC’s own authoritative precinct-to-district crosswalks published alongside each precinct file — no district here is inferred. Congressional plans PlanC2193 (2021) and PlanC2333 (the 2025 redraw); State House PlanH2316, Senate PlanS2168 and SBOE PlanE2106 are unchanged between the two vintages. Both vintages reconcile completely — all 9,657 old and all 9,614 new precincts are accounted for.

Precinct geometries come from the WattsLab precinct API (old map Precincts24G, new map Precincts26P). Overlap was computed in an equal-area projection (EPSG:3083, Texas Centric Albers) as each new precinct's intersection area divided by its total area, so the fractions for a new precinct sum to 1. An earlier version of this article compared the 2024 state file against Dallas County’s own 2026 layer. Both describe the same precincts — the two sets are identical, with no differences either way — but they were drawn by different agencies, so part of what was measured as “change” was two cartographers tracing the same line differently. These figures compare like with like, which is why the unchanged share rose. The approach follows our Harris County 2026 redistricting analysis, and the same method now covers Tarrant County — where two congressional districts left the county entirely — and the state as a whole.
