The largest age group in Oregon was for the group of age 30-34 years with a population of 299,939 (7.13%), according to the 2021 American Community Survey.

At the same time, the smallest age group in Oregon was the 80-84 years with a population of 74,629 (1.77%).

Oregon population by age cohort

To better understand the age distribution of Oregon'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 Oregon'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.

Key stats for each age cohort as per our analysis of U.S. Census Bureau American Community Survey:

  • Oregon's population under 18 was 20.76%, compared to the 22.51% nationwide.
  • Oregon's working population (between 18 and 64) was 61.57%, compared to 61.45% nationwide.
  • Oregon's elderly or the senior population (over 65 age) was 17.66% as compared to 16.04% nationwide.

Oregon population pyramid

Population pyramid for Oregon 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 Oregon's population pyramid:

  • Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Oregon, is 26.3.
  • Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Oregon, is 27.1.
  • Total dependency ratio for Oregon is 53.4.
  • Potential support ratio, which is the number of youth (working age population) per elderly, for Oregon is 3.7.

Key observations

  • Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Oregon, is 26.3.
  • Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Oregon, is 27.1.
