Away from the lights and fountains of the Las Vegas Strip, bulldozers are working overtime as the suburbs of Sin City are bursting out of their seams.

Las Vegas is growing at a staggering rate. Clark county, where the city is located, is home to roughly 2.3 million people, but forecasts predict the population could go beyond 4 million by 2055.

Attracted by the lure of cheaper costs of living, lower taxes, and newly built homes, more than half a million people are expected to flock to southern Nevada in just the next 15 years.
