Arlington was one of the fastest-growing "boomburgs" of the post-WWII era. From its founding in 1884 until the early 1950s, Arlington was a small city of less than 10,000 inhabitants.
Driven by the post-war automotive and aerospace industries, Arlington transformed overnight. In 1950, the population was 7,692. By 1970, it was 90,229. By 1990, the city had reached a population of 261,732 people.
Today, Arlington is a major population center, and is the largest city in Texas that is not a county seat.
