The demographics of a community influence the health needs and outcomes of its population. Understanding the demographic breakdown can help state health officials determine priorities for health promotion and disease prevention.
The age distribution in the United States is shifting. In 2023, more than 59 million adults age 65 and older lived in the U.S., accounting for nearly 18% of the nation’s population. It is estimated that by 2040, there will be more than 78 million older adults age 65 and older, comprising 22% of the total population.
The demographics of the older adult population are also evolving. Historically, more women than men have lived past age 65, and while this trend will most likely continue, the age gap between men and women is expected to shrink in the coming decades. The older adult population will also become more racially and ethnically diverse. Projections indicate that the share of the older adult population that identifies as a racial or ethnic minority will increase from 25% to 40% by 2050.
Older adults generally face more complex health challenges than younger populations. These may include developing aging-related chronic conditions such as cardiovascular disease, cancer or arthritis, as well as struggling with finding their next meal, living safely in their home, getting enough sleep at night and accessing medical care.
Caring for older adults can be challenging. In 2020, there were about 53 million caregivers in the U.S., approximately half of whom were taking care of a parent or parent-in-law. Most caregivers of older adults are spouses or adult children, but decreasing fertility and marriage rates and increasing divorce rates mean that many baby boomers will not have partners or children who can help them live independently as they age. This dynamic will put new and unique stresses on the health care system and challenge how our society currently cares for older adults.

America’s Health Rankings builds on the work of the United Health Foundation to draw attention to public health and better understand the health of various populations. Our platform provides relevant information that policymakers, public health officials, advocates and leaders can use to effect change in their communities.
We have developed detailed analyses on the health of key populations in the country, including women and children, seniors and those who have served in the U.S. Armed Forces, in addition to a deep dive into health disparities across the country.
