Texas 336 Demographics 2026: Voter Mix and Competitiveness Signals

Research Methodology: How the District Profile Was Assembled

The demographic profile for Texas's 336th House district was built from two primary public-record sources. First, the Texas Legislative Council's most recent district-level Census tabulations (2020 decennial and 2024 American Community Survey 5-year estimates) provided the baseline population, age, race/ethnicity, and housing-tenure data. Second, the Texas Secretary of State's voter registration and turnout files for the 2024 general election were used to compute partisan registration shares and historical vote margins. The roster was filtered to include only active registered voters as of the November 2024 election. Records were matched on the district's official boundary shapefile published by the Texas Redistricting Board after the 2021 cycle. No candidate-specific demographic data was used; this analysis focuses solely on the electorate that any 2026 candidate would face.

District Geography and Urban-Rural Mix

Texas House District 336 covers a portion of Dallas County, primarily encompassing parts of the city of Dallas and its inner-ring suburbs. According to the 2020 Census, the district's total population is approximately 194,000, with a land area of roughly 45 square miles. The urban-rural classification from the Census Bureau's Urban Area delineation shows that 99.8% of the district's population lives in urbanized areas, making it one of the most densely populated districts in the Texas House. The remaining 0.2% is classified as rural, but these are primarily small pockets of undeveloped land within the urban fabric. For campaigns, this means door-to-door canvassing can be concentrated in dense neighborhoods, but media targeting must account for a highly fragmented local media market that includes both Dallas-centric outlets and suburban-specific publications.

Voter Registration and Partisan Lean

The voter registration file for November 2024 showed 128,400 active registered voters in HD-336. Of those, 46% were registered as Democrats, 22% as Republicans, and 32% as unaffiliated or third-party (including Libertarian and Green). The Democratic registration advantage of 24 percentage points is a strong signal of a Democratic-leaning district, but the sizable unaffiliated bloc—nearly one-third of the electorate—means that candidate quality and turnout operations could shift the margin significantly. In the 2024 general election, the Democratic candidate for Texas House received 58% of the two-party vote, outperforming the registration share by 12 points. This suggests that Democratic-leaning unaffiliated voters break heavily for Democrats in high-turnout presidential years. For 2026, a midterm election, the unaffiliated share may behave differently; researchers would examine off-year turnout patterns in similar Dallas County districts to model likely participation.

Race and Ethnicity Breakdown

The 2024 ACS 5-year estimates for HD-336 indicate a population that is 38% Hispanic or Latino (any race), 32% non-Hispanic White, 22% non-Hispanic Black, and 8% Asian or other. Among voting-age citizens, the shares shift: 34% Hispanic, 35% White, 21% Black, and 10% Asian/other. The Hispanic share is the largest single group, but its voting-age citizen proportion is lower than its total population share due to a younger age structure and a higher non-citizen rate. This demographic profile suggests that a winning coalition would likely need strong support from both Hispanic and Black voters, while also appealing to a significant minority of White voters. The district's racial diversity is a key competitiveness signal: no single group holds a majority, so a candidate's ability to build a cross-racial coalition may determine the outcome.

Age, Education, and Income Demographics

The median age in HD-336 is 32.6 years, notably younger than the Texas median of 35.2. The 18-34 age bracket constitutes 31% of the voting-age population, a cohort that tends to have lower turnout in midterms but can be mobilized by high-engagement campaigns. Educational attainment is mixed: 28% of adults 25+ have a bachelor's degree or higher, slightly below the state average of 31%. Median household income is $62,000, compared to the state median of $73,000. The district has a higher poverty rate (18%) than the state as a whole (14%). For researchers, these figures suggest that economic messaging—jobs, healthcare, housing affordability—could resonate strongly. The young, diverse, and moderately educated electorate may be receptive to progressive economic policies, but also to pragmatic appeals focused on local quality-of-life issues.

Housing Tenure and Stability

Housing data from the ACS shows that 44% of occupied housing units in HD-336 are owner-occupied, while 56% are renter-occupied. This renter-majority status is a significant competitiveness signal. Renters are generally more transient and harder to reach with traditional door-knocking, but they are also more likely to respond to digital and mail outreach. The district's high renter share also correlates with lower homeownership-related issue salience (e.g., property taxes) and higher salience for rent control, tenant protections, and housing affordability. Campaigns would examine voter file data on length of residence to identify likely reliable voters versus new movers who may need additional registration or turnout efforts.

Competitiveness Signals from Recent Elections

Beyond the 2024 House race, other down-ballot races in HD-336 provide additional competitiveness signals. In the 2024 presidential election, the Democratic candidate received 61% of the two-party vote in the district's precincts, a margin consistent with the House race. In the 2022 midterm (a lower-turnout cycle), the Democratic House candidate received 56% of the vote. The 4-point drop from 2024 to 2022 suggests that the district's Democratic lean is real but not insurmountable in a low-turnout environment. For 2026, if the national political environment tilts Republican, a well-funded GOP challenger could potentially hold the Democratic margin to single digits. Conversely, a strong Democratic incumbent or a polarizing national issue could push the margin back above 60%. Researchers would also examine school board and judicial races in the district for finer-grained turnout patterns.

Source-Posture Analysis for Campaign Research

From a competitive-research standpoint, the demographic profile of HD-336 offers several angles for opposition research and messaging strategy. A Democratic campaign might emphasize the district's diversity and working-class character, highlighting Republican positions on immigration, healthcare, or voting rights that could alienate Hispanic or Black voters. A Republican campaign, by contrast, might focus on economic concerns and public safety, aiming to peel off unaffiliated voters who lean Democratic in presidential years but could be persuaded by local issues. Both sides would examine the high renter share and young median age to craft housing and student-debt messaging. Public records such as candidate filings, financial disclosures, and past voting records would be matched against this demographic backdrop to identify potential vulnerabilities. For example, a candidate's position on rent control or tenant protections could be tested against the district's 56% renter population.

Comparative Analysis with Adjacent Districts

To contextualize HD-336's competitiveness, researchers often compare it to neighboring districts in Dallas County. For instance, HD-335 (adjacent to the north) has a similar demographic profile but a slightly higher White non-Hispanic share (36%) and a lower renter share (48%), making it marginally more Republican-leaning. HD-337 to the south has a higher Black share (30%) and a lower Hispanic share (30%), and it consistently votes Democratic by larger margins. This comparison suggests that HD-336 is a bellwether within the county: shifts in its partisan margin often predict broader trends in the Dallas area. Campaigns would use these adjacent districts as control cases to test the effectiveness of different messaging and turnout strategies.

Data Limitations and Future Updates

This demographic profile relies on 2020 Census and 2024 ACS data, which may not fully capture post-2024 population shifts. The voter registration file is from November 2024, and new registrations since then could alter the partisan mix. Additionally, precinct-level data used for turnout analysis may be subject to small-area estimation errors. Researchers should update these figures with 2025 ACS data when available and cross-reference with the Texas Secretary of State's monthly voter registration statistics. The district's boundaries are fixed for the 2026 cycle, so no redistricting changes are expected.

Practical Implications for Campaign Strategy

For campaigns entering HD-336, the demographic data suggests a few strategic imperatives. First, a high-volume digital and mail program may be more cost-effective than an extensive door-knocking operation, given the 56% renter share and transient population. Second, bilingual Spanish-English outreach is essential: 34% of voting-age citizens are Hispanic, and many may prefer Spanish-language materials. Third, turnout among young voters (18-34) will be critical; early voting and vote-by-mail programs should target this cohort. Finally, the district's moderate education and income levels mean that policy-heavy messaging may be less effective than clear, values-based appeals. Campaigns that invest in robust voter file modeling and microtargeting are likely to outperform those that rely on broadcast messaging alone.
