Census: Seniors population up nationally, but smaller part of Indiana counties

Hoosiers 65 and over, essentially older baby boomers and their parents, make up 15 percent of the state's population. That's generally true for northeast Indiana, except for Steuben County, where 18 percent of the population is retirement age.

Compare that to Sumter County, Florida, west of Orlando, where 54.8 percent are 65 or older, according to 2015 census estimates released last week. The figures also show continued growth among Hoosier minority groups, especially Asians and Hispanics.

While boomers are still prominent, 24-year-olds had the largest population for a single year at 4.7 million nationwide. Twenty-one-year-olds held that position in Indiana, at an estimated 98,213.
