Texas' rapidly-growing population is most likely due to its economy.
Just last year, CNBC named the Lone Star State the best state for business, thanks in large part to the oil industry, which continues to be a major contributor to the state's GDP.
Between 2017 and 2018, the state added over 240,000 jobs, according to the Texas Workforce Commission, with mining and logging accounting for the fastest-growing industries.
But Texas is also beginning to establish a tech industry as well, with Apple, Google and Amazon setting up new offices in Austin. And Inc. magazine dubbed San Antonio a "tech hub" last year thanks to its multiple cybersecurity start-ups.
In fact, according to Census data released last year, San Antonio saw the most population growth between 2016 and 2017 of any large city in the US. When it comes to counties, Harris County, which includes Houston, was the third fastest-growing county in the nation.
In January, moving van rental company U-Haul released its annual report and named Texas as the most popular state to move to for a third year in a row.
"Since Houston is booming, surrounding cities are seeing growth as well," Robert Abidin, U-Haul Company of Northeast Houston president, said in a press release about the report. "Spring is home to the new ExxonMobil® campus, which is bringing thousands of jobs to the area. The oil and gas industry brings people from all over the world to Texas."
