Understanding the Life Expectancy Gender Gap in 2015
In 2015, U.S. females had a life expectancy of 81.2 years, while males had a life expectancy of 76.3 years, resulting in a 4.9-year difference. This gender gap, where females outlive males, is a long-standing pattern in the U.S.. However, 2015 data also indicated a slight decrease in life expectancy for both sexes compared to 2014, with different factors contributing to this trend for men and women.
Data from the National Center for Health Statistics
The life expectancy figures for 2015 are primarily based on data from the CDC's National Center for Health Statistics (NCHS). These statistics confirmed the persistence of the gender gap in life expectancy. The slight overall decline in U.S. life expectancy in 2015 was influenced by varying causes affecting each gender.
Different Mortality Patterns by Gender
A key finding from the 2015 data was the distinct mortality patterns for men and women contributing to the life expectancy gap. The decline in female life expectancy was mainly linked to increases in old-age mortality, whereas the decline for males was largely due to increased midlife mortality.
Factors in Male Midlife Mortality
Increased midlife mortality among males in 2015 was significantly influenced by a higher risk of death from accidental poisoning, including drug overdoses, and homicide. Historically, factors such as societal roles, risk-taking behaviors, and occupational hazards have also contributed to men's lower life expectancy.
Factors in Female Old-Age Mortality
For females, the slight decrease in life expectancy in 2015 was predominantly related to changes in old-age mortality. This included a lower mean age at death for certain conditions like heart disease and some mental illnesses. The historical longevity advantage for women is often attributed to lower rates of smoking and certain cardiovascular diseases.
Comparing Causes of Death in 2015
The leading causes of death in 2015 affected men and women differently. While cancer death rates declined, rates for heart disease, unintentional injuries, and stroke increased, impacting both genders but with varying effects on the overall life expectancy gap.
| Cause of Death (Example) | Male Impact (2015) | Female Impact (2015) |
|---|---|---|
| Accidental Poisoning | Significant contributor to midlife mortality gap. | Less pronounced impact compared to males. |
| Heart Disease | Widening of gap partly due to worsening rates compared to females. | Impact mostly seen in old-age mortality patterns. |
| Homicide | Higher risk, contributing to midlife mortality concerns. | Lower rates compared to males. |
| Cancer | Improved mortality rates for men helped to offset the widening gap. | Improved mortality rates seen, contributing to overall trends. |
Long-Term Trends
The 2015 figures are part of a broader historical trend. After narrowing in the late 20th century, the gender gap in U.S. life expectancy has recently started to widen again, influenced by factors like the opioid crisis and the COVID-19 pandemic. These trends highlight the need to address public health crises impacting various age groups.

Addressing the Gender Longevity Gap
Reducing the gender gap in life expectancy requires addressing the distinct health challenges faced by men and women at different stages of life. This involves targeting issues like substance abuse and mental health in men's midlife and focusing on chronic diseases affecting women in later life. Public health efforts should aim to promote healthy behaviors and preventative care throughout life for all individuals. The 2015 statistics underscore the importance of working towards equitable health outcomes.
