According to the Alzheimer’s Association, by 2030, the segment of the U.S. population age 65 and older will increase substantially, and the projected 74 million older Americans will make up over 20 percent of the total population (up from 16 percent in 2019).

Millions of Americans have Alzheimer’s disease and other dementias. As the size and proportion of the U.S. population age 65 and older continue to increase, the number of Americans with Alzheimer’s disease and other dementias will grow. This number will escalate rapidly in coming years, as the baby boom generation has begun to reach age 65 and beyond, the age range of greatest risk of Alzheimer’s. In fact, the first members of the baby boom generation turned 70 in 2016.

An estimated 5.8 million Americans of all ages have Alzheimer’s disease in 2019. This number includes an estimated 5.6 million people age 65 and older and approximately 200,000 individuals under age 65 who have younger-onset Alzheimer’s.

One in nine people age 65 and older (11 percent) has Alzheimer’s disease.

About one-third of people age 85 and older (32 percent) have Alzheimer’s disease.

Eighty-one percent of people who have Alzheimer’s disease are age 75 or older.

By 2025, the number of people age 65 and older with Alzheimer’s dementia is projected to reach 7.1 million — almost a 27 percent increase from the 5.6 million age 65 and older affected in 2019.
