The largest age group in Kentucky was for the group of age 55-59 years with a population of 308,608 (6.87%), according to the 2021 American Community Survey.

At the same time, the smallest age group in Kentucky was the 85+ years with a population of 74,637 (1.66%).

Kentucky population by age cohort

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

Kentucky population pyramid

Population pyramid for Kentucky 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 Kentucky's population pyramid:

  • Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Kentucky, is 29.0.
  • Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Kentucky, is 25.2.
  • Total dependency ratio for Kentucky is 54.3.
  • Potential support ratio, which is the number of youth (working age population) per elderly, for Kentucky is 4.0.
The graph shows Kentucky's population across different age group and gender, with population on x-axis and population y-axis. The male population is plotted on the left in blue color whereas the female population is plotted on the right in pink color.
