How We Measured The Fastest Growing Cities In the Mount Rushmore State for 2020

To figure out which cities are growing the most, we simply had to look at the growth rates for cities sine the beginning of the decade, according to the American Community Survey put out by the census every year. Specifically:

  • Current Population
  • Population in 2010
  • Growth rate from 2010 to Current (The latest available data which came out in Dec 2018)

We ranked all 18 South Dakota cities with a population over 5,000 people from highest growth rate to lowest.

The city with the highest growth rate during this time was crowned the fastest growing city in the Mount Rushmore State.

And for those of you who are a little rusty with their statistics, you can calculate the growth rate by the following formula:

[Current Population - Population 2010] / [Population 2010]
