The Surprising Statistics on Longevity
According to US government statistics from 2016, approximately 24% of people live to age 90 or beyond, though this figure masks significant differences based on sex and other factors. For instance, nearly 30% of females in the total US population lived into their 90s, while only slightly over 18% of males did. These figures reflect data from the Centers for Disease Control and are part of a broader trend: the 90-and-older population has grown significantly, nearly tripling between 1980 and 2010. This demographic shift is leading researchers to look closer at what it takes to live into the oldest age brackets.
Beyond national data, specific studies highlight factors that influence these percentages. One study examined over 7,000 men and women and found that about 16% of men and 34% of women survived to age 90, reinforcing the gender gap in longevity. Another study focusing on men over 70 found that 41% made it into their 90s, demonstrating that focusing on specific, healthy behaviors can significantly increase the odds. These statistics show that while a notable portion of the population reaches this advanced age, it is far from universal, and the journey is deeply personal and influenced by numerous variables.
The Controllable Factors for Reaching 90+
While genetics play a role in longevity, numerous studies have identified lifestyle choices as crucial determinants, especially for living well into your 90s. These are often within your control and can significantly impact your healthspan and lifespan.
Key Lifestyle Habits for a Long Life
Researchers have pinpointed several behaviors that correlate with a longer life, including for those who reach nonagenarian status.
- Don't Smoke: Avoiding tobacco use is one of the single most impactful choices you can make. Non-smokers are significantly more likely to reach old age compared to smokers.
- Maintain a Healthy Weight: Obesity is a significant risk factor for many chronic diseases that can shorten a lifespan. Maintaining a healthy body mass index (BMI) is associated with a lower chance of premature death.
- Regular Exercise: Consistent physical activity is vital. It improves cardiovascular health, preserves muscle mass and function, and reduces the risk of many age-related conditions. Even moderate exercise, like a daily walk, can make a difference.
- Prevent and Manage Diabetes and High Blood Pressure: Chronic conditions like high blood pressure and diabetes are major health risks, and effective management is critical for longevity. These conditions increase the risk of premature death if left uncontrolled.
- Eat a Healthy Diet: A diet rich in fruits, vegetables, whole grains, and healthy fats, such as the Mediterranean diet, is consistently linked to longer life expectancy. Conversely, avoiding processed foods and excessive red meat is beneficial.
- Manage Stress and Get Good Sleep: Chronic stress can accelerate aging and disease risk, while quality sleep is essential for regulating vital bodily functions.
- Stay Socially and Mentally Engaged: Maintaining social connections and stimulating the mind through activities like reading or puzzles can have protective effects on cognitive function and overall well-being.
The Uncontrollable and Less Predictable
Some factors are simply outside of our direct control, or have less influence than our daily habits, but still shape our longevity potential.
Genetics and Environment
While genetics can influence a baseline lifespan, their impact is less significant than lifestyle choices for most of life. Studies have found specific genetic variants linked to longevity, but these become more influential at extremely advanced ages, like 110 and beyond. Environmental factors, including where you live, air and water quality, and economic stability, also play a part. Access to education and quality healthcare are also significant determinants.
The Gender Longevity Gap
The disparity in longevity between men and women is a well-documented phenomenon. Women generally live longer, and this trend holds true for reaching ages 90 and beyond. While the exact reasons are complex and not fully understood, factors such as biology, hormones, and lifestyle differences are thought to contribute.
Longevity Factors: Men vs. Women
| Factor | Impact on Men (to age 90) | Impact on Women (to age 90) |
|---|---|---|
| Regular Exercise | Significant positive correlation; 90+ minutes daily improved chances by 39% compared to <30 mins. | Also positive; 30-60 minutes daily improved chances by 21% compared to <30 mins. |
| Smoking | Non-smokers twice as likely to reach 90 compared to smokers. | Strong negative correlation, reduces chances significantly. |
| Healthy Weight | Healthy BMI reduces risk of premature death. | Healthy BMI is also a critical factor for longevity. |
| Blood Pressure | High blood pressure increased death risk before 90 by 28%. | Managing blood pressure is crucial for preventing cardiovascular disease. |
| Genetics (Parental Longevity) | Stronger association between paternal longevity and male offspring's chances of reaching 90. | Stronger association between maternal longevity and female offspring's chances of reaching 90. |
The Reality of Life Over 90
Reaching a long life is one thing; living it well is another. Nonagenarians face unique challenges as they navigate this advanced stage of life. Common issues include navigating complex healthcare systems, dealing with limited mobility, and managing chronic health conditions. Mental and emotional well-being are also critical, as is maintaining a sense of purpose.
Common Challenges for Nonagenarians
- Chronic Health Conditions: Most older adults live with at least one chronic condition, such as heart disease or arthritis, which requires ongoing management.
- Mobility and Falls: Declining mobility and balance increase the risk of falls, a leading cause of injury for seniors.
- Cognitive Decline: The risk of cognitive impairment, including dementia, increases with age.
- Social Isolation and Loneliness: Changes in social circles, including the loss of a spouse or friends, can lead to loneliness and isolation, which negatively impacts health.
- Financial Security: Economic insecurity is a reality for many older adults, which can impact access to quality healthcare and other needs.
Despite these challenges, many nonagenarians live fulfilling lives by staying active, maintaining social connections, and focusing on a positive mindset. Personal choices continue to matter greatly, and proactive care can help mitigate many of the common issues associated with extreme old age.

Conclusion: The Path to 90 and Beyond
What percentage of people make it to 90? The answer is dynamic and influenced by a complex interplay of personal choices, genetics, and environment. While average life expectancy continues to rise, reaching nonagenarian status remains a significant milestone achieved by a specific portion of the population, with a notable advantage for women. By focusing on controllable lifestyle factors such as diet, exercise, and avoiding smoking, individuals can significantly increase their personal odds. While genes and other uncontrollable factors play a role, the daily habits we cultivate have the most profound impact on not just our lifespan, but our healthspan—the quality of those later years. The growing population of nonagenarians demonstrates that thriving in advanced age is an increasingly attainable goal with the right approach to health and wellness.
