The demographics of a state influence the health needs and outcomes of the population. Understanding the demographic breakdown can help state health officials determine health promotion and disease prevention priorities. The age distribution in the United States is shifting. According to 2022 data, nearly 58 million adults ages 65 and older live in the U.S., accounting for about 17.3% of the nation’s population. By 2040, that proportion is projected to grow to 22%. When the last of the baby boomer generation ages into older adulthood in 2030, estimates suggest more than 73.1 million older adults will live in the U.S. 

The demographics of the older adult population are also evolving. Historically, more women than men have lived past age 65. While this trend will 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: By 2040, it is expected that racial and ethnic minorities will make up 34% of the population ages 65 and older. A larger proportion of older adults live in rural areas compared with urban areas, and the median age of the suburban population is rising swiftly. 

Older adults generally face more complex health challenges than younger populations. These may include developing aging-related chronic conditions such as cardiovascular disease or Alzheimer's disease, as well as challenges 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 an estimated 53 million caregivers in the U.S., about 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 will put new and unique stresses on the health care system and challenge how our society currently cares for older adults.

Current Reports

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.
