About Houston
Houston is a sprawling port city in Southeastern Texas. An oil boom and continuing international immigration has brought explosive growth to the city, and it is now the fifth largest metropolitan area in the United States and the most diverse large city since 2021. While at first glance, the city appears to be a 9-5 central business district surrounded by a sea of suburbs and strip malls, there are many hidden gems to be discovered.
