The Rapidly Growing Oldest-Old Population
The nonagenarian population—individuals aged 90 to 99—is one of the fastest-growing age segments in the United States. While precise annual figures for a single age like 90 can fluctuate, census data provides powerful insights into the broader trend of individuals aged 90 and older. In a 2011 report, the U.S. Census Bureau highlighted that the 90-and-older population had swelled to 1.9 million by 2010, marking a nearly threefold increase over just three decades. This was a significant shift from the 720,000 individuals reported in this age bracket in 1980.
This demographic expansion is not a fleeting trend but a fundamental change in the American population structure. The aging of the large Baby Boomer generation, who began turning 65 in 2011, and continued improvements in life expectancy, are fueling this growth. Projections indicate this oldest-old population is set to continue its steep climb in the coming decades, profoundly impacting societal resources and services.
Demographic Characteristics of Nonagenarians
The 90-and-older population is not uniform but possesses distinct demographic characteristics that set it apart from younger age groups. Data from sources like the Census Bureau and the Administration for Community Living shed light on the unique profile of this long-lived demographic, including notable differences in gender, living arrangements, and financial status.
A Significant Gender Imbalance
One of the most striking features of the 90+ population is the significant gender disparity. Women overwhelmingly outnumber men in this age group, a trend that becomes more pronounced with increasing age. In 2011, a Census Bureau analysis revealed women outnumbered men nearly 3 to 1 among individuals 90 and older. While the exact ratio can shift, this pattern is consistent across numerous reports and highlights a key consideration for senior care planning.
Evolving Living Arrangements
Living situations among the oldest old differ significantly between men and women. For many nonagenarians, maintaining independence is a priority, but health and mobility issues can often necessitate alternative living arrangements. A 2016 Census Bureau report on the 90+ population found that a notable percentage of men lived with family, while a larger share of women lived alone or were institutionalized. However, living with family is the most common living arrangement for centenarians in racial and ethnic minority groups, highlighting variations across the population.
Financial Landscape and Poverty Rates
Economic circumstances can be particularly challenging for the oldest old, with data showing a higher poverty rate for this group compared to their younger elderly counterparts. Income often comes from Social Security and pensions, and out-of-pocket medical expenses can significantly strain finances. The financial vulnerability of many nonagenarians underscores the importance of public and private support systems.
Health and Mobility in the 90+ Population
Living to 90 often means managing multiple health conditions and changes in physical function. While some individuals remain remarkably healthy, many experience limitations that affect daily life.
Common Health Challenges for the Oldest Old:
- Mobility Limitations: Difficulty walking, climbing stairs, and running errands alone are widespread issues for those 90 and older.
- Chronic Conditions: A high percentage of nonagenarians live with one or more chronic health issues, such as heart disease, arthritis, and diabetes.
- Cognitive Changes: While not universal, cognitive decline and conditions like dementia can become more prevalent in this age group.
Comparison of Nonagenarian Trends Over Time
| Feature | 1980 | 2010 | Trends & Implications |
|---|---|---|---|
| 90+ Population (Approx.) | 720,000 | 1.9 million | Nearly tripled in three decades. Shows rapid growth due to increasing longevity and population size. |
| Gender Ratio (Women to Men) | N/A (high ratio) | ~3:1 | Consistent and growing gender gap with advanced age, impacting care needs. |
| Life Expectancy at 90 (Average Additional Years) | ~3.2 | ~4.6 | Substantial increase, indicating a trend toward living longer once reaching this advanced age. |
| Nursing Home Residency (Approx. for 90-94) | N/A (lower) | 20% | Rising rates of institutionalization reflect increasing care needs for an aging population. |
The Societal Impact of an Aging Population
The demographic shift toward an older population has far-reaching consequences for society, health care, and social support systems. As the nonagenarian population continues to expand, so does the demand for specialized care, assisted living facilities, and in-home support services. The financial implications are significant, affecting programs like Social Security and Medicare as the ratio of retirees to workers shifts. Family caregivers, often aging themselves, also face increasing burdens. The Administration for Community Living offers valuable resources and insights into the landscape of older Americans and the services required to support them.

Conclusion
The question of how many 90 year olds are in the USA points to a larger, more impactful trend: the unprecedented growth of the oldest-old population. While the 2010 census identified nearly 2 million Americans 90 and older, that figure has continued its ascent. This demographic shift is fueled by greater longevity and the aging of the baby-boomer generation. Understanding the characteristics and needs of this resilient population is essential for effectively planning for a future in which a substantial portion of our community is in its tenth decade of life and beyond. The societal and personal implications of this trend will continue to shape public policy and care strategies for years to come.
