Clearwater: Age

In Clearwater . . .
  • 15.2 percent of the population was under 18 in 2021, compared to 24.7 percent in Idaho

  • 56.9 percent of the population was 18 to 64 years old in 2021, compared to 58.7 percent in Idaho

The map showing dependency ratio measures the portion of people who are of non-working age (those under age 18 and those 65 and over) compared to those of working age. We add the number of people under the age of 18 to the number of people aged 65 and older and divide by the number of people aged 18-64. As the dependency ratio increases, there is a growing number of 'dependents' that must be supported by the working population.
