Boomtowns are considered the fastest-growing cities in America due to rapid business and population growth. An example of such a place is Horizon West, Florida, which saw massive five- and eight-year percentage changes in population at 113.72% and 222.30%, respectively. In terms of numbers, the population jumped from 10,093 people in 2010 to 32,530 in 2018. Per capita income also grew from $32,800 to $38,050 over the course of those eight years.
