The number of people reaching retirement age grows every year, bringing new challenges for seniors, their families and those providing care.

There are currently 1.13 million people living in Tennessee who are 65 or older. That number is projected to rise to 1.26 million in 2020, making up 17 percent of the state's population.

By the year 2030, more than one-fifth of all Tennesseans will be age 65 or older, according to the Tennessee Commission on Aging and Disability.

Knox County is currently home to more than 68,000 seniors. That number is projected to rise by 57 percent to more than 106,000 by 2030, representing 20 percent of the Knox County population.

In other East Tennessee counties, the percentage of the county's population that will be 65 or older is even higher. According to the Tennessee Commission on Aging and Disability, in 2030, senior citizens will make up the following percentages in these East Tennessee counties: Hamblen County - 23 percent; Sevier County - 26 percent; Blount County - 27 percent; Anderson County - 27 percent; Campbell County - 28 percent; Fentress County - 31 percent, Cumberland County - 42 percent.
