Is being in an area of New Hampshire that’s growing quickly a good thing or a bad thing?
Depends on who you ask.
Some want bigger, more exciting cities like Manchester and Nashua, while others want peace and quiet like in East Merrimack and Suncook, thank you very much.

Saturday Night Science
Methodology: How We Measured The Fastest Growing Cities In the Granite State for 2026
To figure out which cities are growing the most, we used Saturday Night Science to look at the growth rates for cities since 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 2024)
We ranked all 26 New Hampshire 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 Granite 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].
The data has been updated for 2026. This report is our eleventh time ranking the fastest growing cities in New Hampshire.
