The largest age group in Maine was for the group of age 60-64 years with a population of 107,649 (7.93%), according to the 2021 American Community Survey.

At the same time, the smallest age group in Maine was the 80-84 years with a population of 30,862 (2.27%).

Maine population by age cohort

To better understand the age distribution of Maine's population, we divided it into the following 3 cohorts:

  • Children : Under the age of 18 years
  • Adults (working population): Between the age of 18 and 64 years
  • Seniors: 65 years and above
The pie chart shows Maine's population divided into segments, with each segment representing an age cohort. The area of each segment is in the same proportion of a circle as the population of the cohort is of the total population.

Here's the population for each of the three cohorts.

  • Maine's elderly or the senior population (over 65 age) was 20.69% as compared to 16.04% nationwide.

Maine population pyramid

Population pyramid for Maine is charted below using the estimates from U.S. Census Bureau's American Community Survey 5-Year estimates. A wide base suggests population increase, narrow base indicates declining birth rates.

Key stats from our analysis of the Maine's population pyramid:

  • Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Maine, is 23.9.
  • Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Maine, is 32.3.
  • Total dependency ratio for Maine is 56.2.
  • Potential support ratio, which is the number of youth (working age population) per elderly, for Maine is 3.1.

About this dataset

Context

The dataset tabulates the data for the Maine population pyramid, which represents the Maine population distribution across age and gender, using estimates from the U.S. Census Bureau American Community Survey 5-Year estimates. It lists the male and female population for each age group, along with the total population for those age groups.

Key observations

  • Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Maine, is 23.9.
  • Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Maine, is 32.3.
  • Total dependency ratio for Maine is 56.2.
