Let me tell you something about Harris County. I've watched this place grow from a sprawling collection of neighborhoods into the third-most populous county in America, and honestly, it never stops surprising me.
If you're moving here, doing business here, or just trying to understand what makes this corner of Southeast Texas tick, you've come to the right place. Harris County isn't just Houston (though that's what most people think). It's 1,700 square miles of bayous, strip malls, world-class medical facilities, oil refineries, and some of the best food you'll ever eat.
Let me walk you through everything you need to know.
What Exactly Is Harris County?
Harris County sits on the Gulf Coast Plain in Southeast Texas, about 50 miles inland from the Gulf of Mexico. Named after John Richardson Harris, who founded the first settlement here in 1826, the county was officially created in 1836, the same year Texas won its independence from Mexico.
Today, Harris County is home to roughly 4.7 million people. That makes it larger than 25 individual U.S. states by population. The county seat is Houston, the fourth-largest city in the United States.
But here's what throws people off: Harris County contains 34 incorporated cities and numerous unincorporated areas. You could live in Pasadena, Baytown, Bellaire, or West University Place and still be a Harris County resident. The jurisdictional overlap gets confusing fast, especially when you're figuring out which government office handles what.
A Brief History (That Actually Matters)
John Richardson Harris established Harrisburg in 1826 along Buffalo Bayou. The settlement became a trading post, and honestly, location was everything. Those bayous provided natural transportation routes that would eventually make Houston a major port city.
When Augustus and John Allen founded Houston in 1836, they basically stole Harrisburg's thunder by making their new city the county seat. Harrisburg got absorbed into Houston decades later, but you can still visit Harrisburg Boulevard and see historical markers if you're into that sort of thing.
The county exploded after the Lucas Gusher at Spindletop in 1901 launched the Texas oil boom. Houston became an energy capital, the Port of Houston opened in 1914, and Harris County never looked back. The NASA Johnson Space Center arrived in 1961, cementing the county's role in aerospace alongside energy.
Geography and Climate: What You're Really Getting Into
The Bayou System
The county has over 2,500 miles of natural waterways. Buffalo Bayou, Brays Bayou, White Oak Bayou, and Greens Bayou are the main arteries. These aren't scenic mountain streams. They're slow-moving, muddy channels that flood when we get tropical storms or hurricanes.
After Hurricane Harvey dumped 50+ inches of rain in 2017, the county invested billions in flood control. The Harris County Flood Control District manages detention basins, reservoirs, and buyout programs in flood-prone areas. If you're buying property here, check the flood maps first. Seriously.
Climate Reality Check
Humid subtropical climate means:
-
Summer: May through September, often hitting 95-100°F with 70-80% humidity. The heat index regularly exceeds 110°F.
-
Winter: December through February, usually 40-60°F. We get maybe one or two freezes per year.
-
Hurricane Season: June through November, with peak activity August through October.
-
Rain: About 50 inches annually, but it comes in intense bursts rather than gentle drizzles.
No state income tax sounds great until you factor in property taxes and the cost of running your AC 9 months a year.
The Major Cities Within Harris County
Houston
The big one. 2.3 million people within city limits, with the Greater Houston metro area pushing 7 million. Houston is unzoned, which means you'll find a church next to a strip club next to a taco truck. It's chaotic and weirdly functional.
Downtown Houston houses the business district, sports stadiums (Minute Maid Park, Toyota Center), and the Theater District. The Galleria area offers high-end shopping. Montrose is the historic artsy neighborhood. The Energy Corridor along I-10 west is where oil companies built their campuses.
Pasadena
Population around 150,000. Home to massive petrochemical plants and refineries. The Pasadena Strawberry Festival happens every May, though honestly, most strawberries now come from elsewhere. It's a blue-collar city with good schools and more affordable housing than inner-loop Houston.
Baytown
East of Houston along I-10, population about 80,000. The ExxonMobil Baytown Refinery is one of the largest in the country. If you work in petrochemicals, you probably know Baytown well. Also home to the San Jacinto Monument, commemorating Texas independence.
Bellaire
A small city (about 19,000 people) completely surrounded by Houston. Excellent schools, tree-lined streets, and property values that make your eyes water. Think of it as an upscale suburban enclave that happens to be 10 minutes from downtown.
Other Notable Cities
-
Pearland: Rapidly growing suburb to the south
-
Humble: Northern suburb, more affordable
-
La Porte: On the bay, with maritime industry
-
Tomball: Northwest area, still has some small-town feel
-
Jersey Village: Small city in northwest Harris County
-
West University Place: Another wealthy enclave near Rice University
Government Structure and Services
Harris County operates under the Commissioners Court system. One County Judge (an administrative role, not judicial) and four County Commissioners represent different precincts. This gets political fast because precincts have shifted from Republican to Democratic in recent elections, making Harris County a major battleground.
What the County Actually Does:
-
Operates the jail system (one of the largest in the country)
-
Maintains roads in unincorporated areas
-
Runs health services through Harris Health System
-
Handles property tax assessment and collection

The Economy: Energy, Medicine, and Everything Else
Energy Sector
Houston is the energy capital of the world. The major oil companies (ExxonMobil, Shell, Chevron, BP) have significant operations here. The Port of Houston is the nation's largest petrochemical port. When oil prices crash, the county feels it, but the economy has diversified enough to weather the storms better than in the 1980s.
Texas Medical Center
The largest medical complex in the world sits in Houston. It includes MD Anderson Cancer Center, Texas Children's Hospital, Houston Methodist, Memorial Hermann, and Baylor College of Medicine, among others. Over 106,000 people work in the Med Center. If you need specialized medical care, this is where you want to be.
Port of Houston
The port handles more international tonnage than any other U.S. port. It's a major job creator and economic engine, driving logistics, manufacturing, and trade throughout the region.

Does Harris County flood a lot?
