The number of Americans living with Alzheimer's is growing — and growing fast. An estimated 5.7 million Americans of all ages have Alzheimer's.

An estimated 5.7 million Americans of all ages are living with Alzheimer's dementia in 2018. This number includes an estimated 5.5 million people age 65 and older and approximately 200,000 individuals under age 65 who have younger-onset Alzheimer's.

• One in 10 people age 65 and older (10 percent) has Alzheimer's dementia.
• Almost two-thirds of Americans with Alzheimer's are women.
• Older African-Americans are about twice as likely to have Alzheimer's or other dementias as older whites.
• Hispanics are about one and one-half times as likely to have Alzheimer's or other dementias as older whites.

As the number of older Americans grows rapidly, so too will the numbers of new and existing cases of Alzheimer's. Today, someone in the United States develops Alzheimer's every 65 seconds. By mid-century, someone in the United States will develop the disease every 33 seconds.
