What do current statistics say about male longevity?
Demographic data from various sources provide insight into the probability of a man reaching 90. It's important to distinguish between life expectancy at birth and the probability of surviving to a certain age if you've already reached a later milestone. A 2014 study cited that more than one-fifth of 70-year-old men will make it to 90. This demonstrates that if a man can avoid early-life mortality risks, his chances of reaching an advanced age improve significantly.
More recently, a study focusing on a cohort of Norwegian men born between 1925 and 1928 found that 16% had reached 90 by 2018. While this is a specific group and not a national average, it reinforces that reaching this age is achievable for a notable portion of the population. Data from the Social Security Administration's actuarial tables can also help predict these probabilities. For example, a man who is 65 today has a different probability of reaching 90 than a baby born today due to improvements in modern medicine and public health. The overall trend shows an increasing number of men living to older ages, though the proportion remains significantly lower than for women.
Key factors influencing male longevity
Many elements contribute to whether a man will live a long life. These can be broadly categorized into biological and lifestyle factors.
Biological and genetic factors
- Genetics: Approximately 20-30% of the variation in human lifespan can be attributed to genetics, according to twin studies. Specific genes related to metabolism and DNA repair may play a role.
- Hormonal differences: The male sex hormone testosterone, which offers evolutionary advantages in youth, may contribute to higher risks of conditions like cardiovascular disease later in life. Women have two X chromosomes, which may also offer a protective effect against certain age-related diseases.
Modifiable lifestyle factors
- Smoking: One of the most significant predictors of longevity is smoking status. A study of men in Norway showed that never-smokers were much more likely to reach 90 than current smokers.
- Physical Activity: Regular exercise, even in moderate amounts, has been shown to extend life expectancy. A 2019 study highlighted that men who were physically active for at least 90 minutes a day were significantly more likely to reach 90 compared to those who were active for less than 30 minutes.
- Diet and Weight: Poor nutrition, obesity, and related conditions like high cholesterol and diabetes are linked to lower survival rates. A healthy, often plant-based, diet can mitigate these risks.
- Alcohol Consumption: Risky levels of alcohol consumption contribute to chronic diseases that shorten lifespan, such as liver disease.
- Healthcare Engagement: Men are typically less likely than women to seek regular medical care. This can lead to the delayed detection and management of health issues, impacting overall longevity.
Longevity comparison: Men vs. women
The most striking feature of longevity data is the persistent gap between men and women. The reasons are complex and multifactorial..
| Feature | Men | Women |
|---|---|---|
| Life Expectancy (2023, US) | 75.8 years | 81.1 years |
| Survival to 90 | Roughly 14-20% (dependent on cohort) | Approximately 20-34% (dependent on cohort) |
| Centenarian Population (2020, US) | 21.2% | 78.8% |
| Factors Contributing to Gap | Higher rates of heart disease, cancer, accidents, and suicide at younger ages. Less frequent healthcare engagement. | Longer healthspans are not guaranteed, but they are more likely to live with disability rather than die from certain diseases earlier. |
Conclusion
While what percent of men live until 90 fluctuates depending on the population cohort and is still notably lower than for women, it is a milestone increasingly reached by a portion of the male population. Recent data suggests that for certain groups, the percentage is in the double digits, especially for those who adopt and maintain healthy habits. Factors such as genetics, access to healthcare, and socioeconomic status all play a part, but modifiable lifestyle choices like regular exercise, abstaining from smoking, managing weight, and reducing alcohol intake have a powerful influence on extending a man's life and healthspan. Focusing on these areas offers the most control over one's long-term health prospects. As public health continues to improve, the number of men celebrating their 90th birthday will likely continue its upward trend.

How to increase your chances of living longer
- Embrace Regular Physical Activity: Aim for consistent moderate-intensity exercise to lower disease risk and increase longevity.
- Prioritize a Healthy Diet: Adopt a plant-based, whole-food diet rich in fruits, vegetables, nuts, and whole grains to improve overall health and manage weight.
- Quit Smoking: Eliminating smoking is one of the single most impactful changes for improving long-term survival.
- Manage Stress: Find healthy outlets for stress, such as meditation or yoga, to reduce the risk of inflammation and cardiovascular disease.
- Strengthen Social Connections: Combat loneliness and isolation by maintaining strong relationships with family and friends, which is linked to better health and longevity.
- Improve Sleep Hygiene: Aim for seven hours of restful sleep a night to support metabolism, mood, and immune function.
- Address Substance Use: Be aware that men are more likely to abuse substances; addressing anxiety or depression that leads to self-medication is crucial.
