Two Sides
of the Bay.
A look at who actually lives in two of the Coastal Bend’s most distinctive ZIP codes — Corpus Christi’s 78418 and the small island town of Port Aransas — and how their populations tell two very different stories.
Drive south on Padre Island Drive past the JFK Causeway, and you’ve entered ZIP 78418 — Corpus Christi’s Flour Bluff and North Padre Island corridor. Keep going north up Mustang Island instead, and you’ll hit Port Aransas: a small fishing-and-tourist town that empties and fills with the seasons.
They share a coastline. They share a county line, more or less. But the people who call them home? Almost nothing alike.
By the numbers.

Where they diverge.
The headline differences, side by side.
78418 is families, schools, and military households — a coastal Texas suburb still raising kids. Port Aransas is retirees, second homes, and small-business owners — an island that emptied after Harvey and is rebuilding fast.
