About Houston Zip Codes

Our Mission

Houston Zip Codes exists to make comprehensive, trustworthy Houston-area zip code data easy to find, easy to read, and free to use. We built this site for the people who actually need this information: families planning a move to the Houston metro, real estate professionals comparing markets, marketers building local audiences, journalists researching neighborhood trends, and academic researchers studying urbanization in one of the fastest-growing regions in the United States. Anyone trying to understand a Houston zip code shouldn't have to stitch together a dozen government PDFs and paywalled real-estate dashboards — that work is done here.

What You'll Find

Every zip code page on this site brings together the data points people most often look up:

• Demographics — population, age distribution, household size, racial composition, and diversity.
• Housing — median home value, median rent, ownership rates, and housing inventory.
• Income and education — household income, per-capita income, and educational attainment.
• Climate — Houston-area weather norms and seasonal averages.
• Neighborhoods — the named neighborhoods inside each zip code and what they're known for.
• Rankings — how each zip code compares on the metrics that matter most to readers.
• Comparisons — side-by-side comparisons of any two Houston zip codes.

Data Sources

We rely on authoritative public-sector data sources so the numbers on the site can be verified and trusted:

• U.S. Census Bureau — American Community Survey (ACS) 5-Year Estimates for demographics, income, housing, and commute data.
• United States Postal Service (USPS) — zip code definitions, ZCTA boundaries, and postal-area classifications.
• NOAA — National Oceanic and Atmospheric Administration climate normals.
• Other public sources — municipal open-data portals and federal datasets where they add useful context.

Our Approach

Houston Zip Codes is free, accessible, and intentionally simple. There is no paywall, no required signup, and no email gate hiding the data behind a form. We believe public information should be presented in a public way — readable on any device, indexable by search engines, and citable in your own writing. The site is supported by lightweight advertising so it can stay free.

Who Writes This Site

Every page on Houston Zip Codes is compiled and reviewed by the Houston Zip Codes Data Team — a small group of data analysts and local-market researchers who specialize in turning raw federal datasets into plain-English neighborhood profiles. We do not accept paid placements, sponsored "best neighborhood" rankings, or real-estate referral fees that would bias what the numbers say. When we describe a ZIP code as affordable, family-oriented, or flood-prone, that judgment is derived directly from the underlying Census, FEMA, and NOAA data — not from anyone paying to be featured.

How We Build Each Page

Each ZIP code page is generated from the authoritative datasets listed above and then layered with original analysis written by our team:

• We map each ZIP Code Tabulation Area (ZCTA) to its ACS 5-Year Estimate records for population, income, housing, education, and commute data.
• We compute affordability ratios — home-price-to-income and rent-to-income — and benchmark every metric against the Houston metro average so readers see context, not just a number.
• We cross-reference FEMA flood-zone designations and historical disaster declarations so flood risk is presented honestly alongside the demographic data.
• We write a unique neighborhood profile, affordability assessment, and livability summary for each area based on its specific data signature — denser urban ZIPs, affluent suburbs, and working-class communities each read differently because their data is different.

Where a figure is an estimate or a modeled value rather than a direct Census count, we say so. Our goal is that a journalist, lender, or family could cite any number on this site and trace it back to its public source.

Part of a Larger Network

Houston Zip Codes is one site in a broader network of zip-code-focused data sites covering U.S. cities, states, and regions. Each site in the network shares the same goal: clean, well-sourced, free-to-read zip code information for the place it covers. You can find more cities and states linked in our footer.

Update Frequency

We refresh the dataset annually after the U.S. Census Bureau releases new ACS 5-Year Estimates and after USPS publishes updated zip code boundary data. Pages are then re-generated and re-indexed so the information you see reflects the latest publicly available figures.
