ZipCodeDex — demographics for every US ZIP code
Population, household income, housing values, education and employment for 33,000+ American ZIP codes, sourced straight from the Census Bureau's ACS 2024.
Every US ZIP code, decoded
Moving to 10001 in Manhattan? Eyeing an investment near 90210? The numbers should come first. ZipCodeDex is an own product that publishes the full demographic profile of every ZIP code in America — free, open and with no registration, pulled directly from the official census source.
Its users range from families shortlisting neighbourhoods to real-estate investors benchmarking areas and marketing or expansion teams sizing up income and population before committing budget to a territory.
Four ways to explore the data
- Search demographics. Look up any of 32,007+ ZIP profiles — 10001 in New York, for instance, shows 30,511 residents and a $129,852 median income.
- Compare ZIP codes. Two areas side by side with detailed metrics and percentage differences, so live-or-invest decisions rest on data rather than gut feel.
- Browse rankings. Richest, most populated, most educated, best-value, youngest and oldest ZIP codes, nationally and per state.
- Explore by state. All 50 states plus DC, each with aggregate statistics, city breakdowns and its top-ranked areas — 1,678 ZIP codes in California alone.
- Flexible search. ZIP, city or county all work as entry points: 90210, Miami and Cook County land on the right pages.
- No paywall anywhere. Free and open access to the whole dataset, no account needed.

Engineering notes
ZipCodeDex is a fully custom build: a Laravel + PHP backend on a MySQL database structured to serve tens of thousands of profiles, comparisons and rankings with fast page loads. There is no generic theme and no plugin layer — each page type (ZIP profile, state hub, ranking, compare view) is designed around the search it answers.
The core of the project is programmatic SEO: turning one census dataset into tens of thousands of unique, interlinked URLs organised by state and city, backed by XML sitemaps and structured data for complete indexation.
