Knox County saw a 2.2% increase in population in the past 10 years, according to the U.S. Census Bureau.

The Census released formal population figures Aug. 12 for states, counties and communities with populations more than 5,000 people based on the 2020 count. This is the first formal count since 2010.

Censuses are conducted every 10 years to determine the number of representatives that states will have, and to determine legislative and county political apportionment.

Maine saw a 2.6% population increase (33,998 people) from 2010 to 2020, increasing to 1,362,359.

Rockland’s population declined by 361, falling to 6.936 in 2020. The city’s population reached a peak of 9,284 residents in 1950 and declined in all but one Census since then.

Details on the demographics of the communities were not immediately available. Details will show the number of people who moved to the community since the prior Census.

Rockland Mayor Ed Glaser said housing pressures are more than just providing affordable housing for people who live here.

“As Rockland becomes even more attractive to people who don’t live here full time, whether they are summer residents, or people who invest in short-term rental properties, we change who is using our limited supply of housing. People who want to live here full time can’t afford it, families can’t afford it, workers can’t afford it.

“I’m not sure what we can do to reverse the trend of the last 20 or more years, but this just shows that what we’ve been doing hasn’t worked. If we continue to lose population, we lose the energy that makes this the place we want to live. Rockland has never been just a summer community, and if it continues, we will turn our back on our history and what has made Rockland the economic engine of the Mid-coast. I don’t like it, we have to turn it around,” Glaser said.
