Understanding the "Oldest Old" Demographic
A Snapshot of the 85+ Population
According to data from the 2020 census and related reports, the population of Americans aged 85 and over is not just growing but doing so at a faster rate than other age groups. This group is often referred to as the “oldest old.” The fact that roughly 1.9% of the country lives beyond this threshold highlights major societal and medical advancements. As life expectancies have risen, so has the need to understand the unique characteristics and needs of this long-lived population.
The Impact of the Silver Tsunami
The aging of the Baby Boomer generation is the primary driver behind this population shift. The U.S. Census Bureau projects that by 2040, the 85+ population will more than double from its 2022 size. This demographic change, sometimes called the “silver tsunami,” will have a profound effect on national infrastructure, social services, and families. It requires a forward-thinking approach to planning for long-term care, housing, and healthcare accessibility.
Shifting Demographics and Living Arrangements
Who Makes Up the 85+ Group?
While the overall percentage of Americans over 85 is still relatively small, the demographics within this group reveal interesting trends. In 2022, there were 184 women for every 100 men among people aged 85 and older, a significant disparity that reflects differences in life expectancy. Additionally, the racial and ethnic composition of the older population is becoming more diverse. Projections indicate a substantial increase in older Americans from racial and ethnic minority populations in the coming decades, altering the support needs and cultural considerations for senior care.
Living Independently vs. With Support
One common misconception is that most very old people live in nursing homes. However, a 2023 analysis of census data revealed that less than 10% of 85-year-olds live in a nursing facility. The vast majority live in community settings. This includes:
- Living with family, such as a spouse or adult children.
- Residing alone in independent living, assisted living, or their own homes.
- Participating in multigenerational households.
This data highlights the importance of in-home care services, family support, and community-based programs. It underscores that while institutional care is a component of senior living, most older adults prefer to and do age in place with the right support systems.
The Health and Lifestyle of the Oldest Old
Common Health Challenges
While many people over 85 maintain a high quality of life, the risk of chronic health conditions increases with age. This age group is disproportionately affected by a number of serious health issues:
- Chronic Diseases: Almost 93% of seniors have at least one chronic condition, such as heart disease, hypertension, or diabetes.
- Dementia: The prevalence of dementia rises sharply in this age group, impacting cognitive function and daily life.
- Falls: One in four older adults falls each year, and falls are a leading cause of fatal and non-fatal injuries.
- Behavioral Health Issues: Depression and anxiety can complicate the management of other medical conditions.
Key Comparisons: Health and Care Needs
| Feature | 65-84 Age Group | 85+ Age Group |
|---|---|---|
| Chronic Conditions | High prevalence, often manageable | Higher prevalence, often multiple conditions |
| Life Expectancy | Average additional years (2022): 18.9 years for those reaching 65 | Average additional years beyond 85 is shorter, but a significant portion live well into their 90s |
| Long-Term Care Need | Lower likelihood of needing intensive daily care | Increased likelihood of needing help with daily activities |
| Mobility Concerns | May face mobility issues but often maintain more independence | Increased risk of falls and limited mobility |
The Future of Living Longer
The increasing number of Americans living beyond 85 highlights the success of public health and medical interventions. However, it also brings forward critical questions about how society will support this growing demographic. Financial planning for longevity, expansion of long-term care options, and a greater emphasis on preventive care and social engagement will be crucial for ensuring a high quality of life for the oldest old. The focus is not just on extending lifespan, but on extending "healthspan"—the number of years lived in good health.

Conclusion
The fact that a growing number of Americans are living past 85 is a positive indicator of societal progress, but it requires adaptation and strategic planning. By understanding the demographic trends, addressing common health challenges, and evolving our care systems, we can ensure that longer lives are also healthier and more fulfilling. The conversation around what percentage of Americans live over 85 is a starting point for a broader discussion on how to support and celebrate this remarkable demographic shift.
