The largest age group in Indiana was for the group of age 15-19 years with a population of 471,419 (6.98%), according to the 2021 American Community Survey.

At the same time, the smallest age group in Indiana was the 80-84 years with a population of 115,344 (1.71%).

Indiana population by age cohort

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

Indiana population pyramid

Population pyramid for Indiana 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 Indiana's population pyramid:

  • Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Indiana, is 30.0.
  • Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Indiana, is 24.1.
  • Total dependency ratio for Indiana is 54.1.
  • Potential support ratio, which is the number of youth (working age population) per elderly, for Indiana is 4.1.

Key observations

  • Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Indiana, is 30.0.
  • Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Indiana, is 24.1.
