The largest age group in South Carolina was for the group of age 55-59 years with a population of 342,145 (6.74%), according to the 2021 American Community Survey.

At the same time, the smallest age group in South Carolina was the 85+ years with a population of 86,049 (1.69%).

South Carolina population by age cohort

To better understand the age distribution of South Carolina'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 South Carolina'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.
