Is being in an area that’s growing quickly a good thing or a bad thing?

Depends on who you ask. Some want bigger, more exciting cities like Portland and Lewiston, while others want peace and quiet like in Gardiner and Belfast, thank you very much.

But today we’re going to put opinions aside and just look at the cold hard facts — over the past five years, which cities in Maine have the grown the fastest.

After getting knee deep in the Census’s American Community Survey, we emerged with this set of cities in the Pine Tree State that have people climbing over each other to get in.

How We Measured The Fastest Growing Cities In Pine Tree State

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

  • Population in 2017
  • Population in 2010
  • Growth rate from 2010 to 2017 (The latest available data which came out in Dec 2018)

We ranked all 19 Maine 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 Pine Tree State.

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

[Population 2017 – Population 2010] / [Population 2010]
