The United States welcomes more immigrants than any other country, and Texas welcomes more migrants—foreign and domestic—than any other state. Nearly half of all new arrivals to the state are foreign born. With a population of over 4 million immigrants, Texas is one of the top three states in terms of the number of foreign born living within its borders. Immigration to Texas has been both a cause and consequence of rapid regional growth. The strong economy and the Texas business model—low taxes, few regulations and a low cost of labor—have attracted many businesses and workers in recent decades. This influx has, in turn, stimulated more growth.
