These two U.S. cities grew the most (showed the largest absolute population increases) during the decade of the 1990's. They are in neighboring states and one is a capital city. Can you name them?

During the 1990s, two cities in the American Southwest experienced remarkable population surges, showing the largest absolute increases across the United States. These dynamic urban centers are Las Vegas, Nevada, and Phoenix, Arizona. Their rapid expansion was a testament to a broader demographic shift towards the Sun Belt, driven by economic opportunities, a desirable climate, and a relatively lower cost of living compared to other major West Coast hubs.

Las Vegas, in particular, was the fastest-growing metropolitan area in the country during this decade. Its boom was heavily fueled by an explosion in the tourism and hospitality industry, marked by a mega-resort construction spree that created numerous job opportunities. Many new residents were drawn from neighboring California, seeking employment and a more affordable lifestyle. The city's 24/7 entertainment appeal and abundant sunshine also played a significant role in attracting a diverse influx of people.

Just one state over, Phoenix, the capital and largest city of Arizona, mirrored this impressive growth. The Greater Phoenix area saw its population increase by nearly half from 1990 to 2000. Like Las Vegas, Phoenix benefited from a robust economy that was diversifying beyond its traditional agricultural roots into high-tech and services, alongside its appealing warm desert climate. Both cities represent a significant chapter in American urban development, showcasing how western cities became magnets for growth at the close of the 20th century.
