North Las Vegas is one of two cities in the Las Vegas area, along with Henderson, to rank among the 25 fastest growing cities that had at least 50,000 residents in 2000. Many of the newest residents of Clark County moved there from California. The area has also attracted many new Hispanic residents.

4. Gilbert, Arizona
> Population growth 2000-2018: 111.7%
> Population in 2000 (Census): 109,697
> Population in 2010 (Census): 208,453
> Population in 2018 (5-yr ACS): 232,176

Trailing just three other cities for population growth, the population of Gilbert, Arizona, grew by 111.7% between 2000 and 2018, more than doubling in size from 109,697 to 208,453. Low violent crime and job opportunity are among the numerous factors that can attract new residents to a city and help explain Gilbert’s remarkable population growth. The city’s 2018 violent crime rate of 94.6 incidents per 100,000 people and unemployment rate of 3.5% are each among the lowest for U.S. cities.

3. Louisville, Kentucky
> Population growth 2000-2018: 140.2%
> Population in 2000 (Census): 256,231
> Population in 2010 (Census): 597,337
> Population in 2018 (5-yr ACS): 615,478

Compared with other fast-growing cities, Louisville has had an exceptionally large population — even before its 140% growth since 2000. Nearly all of Louisville’s 21st century growth occurred from 2000 to 2010, when the city more than doubled its population, adding over 340,000 new residents. After that period, growth slowed dramatically, and the city added just over 18,000 new residents since 2010.

2. Elk Grove, California

> Population in 2000 (Census): 60,000
> Population in 2010 (Census): 153,015
> Population in 2018 (5-yr ACS): 166,228

1. Mckinney, Texas
> Population growth 2000-2018: 203.0%
> Population in 2000 (Census): 54,369
> Population in 2010 (Census): 131,117
> Population in 2018 (5-yr ACS): 164,760

Mckinney — one of three cities in Texas on this list — more than tripled in size between 2000 and 2018. This Dallas-area suburb had by far the largest growth by percentage of any large city. Like many other cities on this list, Mckinney experienced a large population boom — adding over 75,000 residents — from 2000 to 2010, but growth has since leveled off. While the population increase of over 33,000 people from 2010 to 2018 is significant, it is nowhere near the level of the previous decade.
