Harris County Is One of the Most Diverse Counties in the U.S.

Tejano families worked this land long before Houston was a city. After emancipation, a large Black community grew here and later expanded during the Great Migration. Those families built neighborhoods and churches that still anchor the east and north sides. Starting in the 1970s, new arrivals from Central America, Southeast Asia, and beyond added more languages and foodways.

Work kept pulling people in. Oil and refineries needed hands. The Texas Medical Center needed doctors, nurses, and support staff. The port drew labor from around the world. Those three engines kept the door open for decade after decade.

Today no single group makes up half the county. That is why Harris ranks among the country's most diverse large counties, and it is part of what makes Houston feel like several cities in one.
