The largest age group in North Dakota was for the group of age 20-24 years with a population of 62,395 (8.07%), according to the 2021 American Community Survey.

At the same time, the smallest age group in North Dakota was the 80-84 years with a population of 14,499 (1.87%).

North Dakota population by age cohort

To better understand the age distribution of North Dakota'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 North Dakota'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.

About this dataset

Context

The dataset tabulates the data for the North Dakota population pyramid, which represents the North Dakota 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.
