1940
- Overall life expectancy: 62.9 years
- Women: 65.2 years
- Men: 60.8 years
The United States began the 1940s on an upswing, with life expectancy up sharply from 58.5 years in 1936. The nation was still struggling with the economic devastation of the Great Depression. The 1940s also brought significant public health landmarks, including the mass production of penicillin and the DTP shot, which combined the pertussis, diphtheria, and tetanus vaccines.
1941
Overall life expectancy:64.8
Women: 66.8
Men: 63.1
Life expectancy increased by nearly two years from 1940 to 1941. This could be due to factors like improved public health measures or the wartime mobilization effort.
1942
Overall life expectancy: 66.2
Women: 67.9
Men: 64.7
Life expectancy jumped another 1.4 years in 1942. While World War II may have disrupted some aspects of healthcare, it’s also possible that wartime advancements in medicine had a positive impact. However, some scholars believe a change in how life expectancy was calculated, starting in 1948, may have made the increase from 1940 to 1942 look more dramatic than it really was.
1943
Overall life expectancy: 63.3
Women: 64.4
Men: 62.4
Life expectancy dropped nearly three years from 1942 to 1943. This decline likely reflects the impact of World War II on public health and resource allocation.
1944
Overall life expectancy: 65.2
Women: 66.8
Men: 63.6
Life expectancy rebounded by almost two years in 1944. This could be due to a number of factors, including:
- The war starting to wind down, easing some of the strain on public health resources.
- Advancements in battlefield medicine being applied to civilian healthcare.
- Increased focus on public health measures to prevent outbreaks of diseases like influenza.
1945
Overall life expectancy: 65.9
Women:67.9
Men: 63.6
Life expectancy rose slightly again in 1945, the year World War II ended. The return of soldiers from active duty may have contributed to a slight decrease in the mortality rate for young men. Additionally, the end of wartime rationing may have improved access to nutritious food for the general population.
1946
- Overall life expectancy: 66.7 years
- Women: 69.4 years
- Men: 64.4 years
Life expectancy continued a slow but steady climb in 1946. This could be due to factors like:
- The continued demobilization of the military, leading to a larger pool of healthcare providers.
- Increased investment in medical research and development.
- Improved public health infrastructure, including better sanitation and sewage systems.
1947
- Overall life expectancy: 66.8 years
- Women: 69.7 years
- Men: 64.4 years
Life expectancy remained relatively flat in 1947. This may be because the positive effects of the war’s end were starting to level off.
1948
- Overall life expectancy: 67.2 years
- Women: 69.9 years
- Men: 64.6 years
Life expectancy ticked up slightly in 1948. It’s important to note that this year also marked a change in how life expectancy was calculated. This change may have resulted in a slightly artificial increase compared to previous years.
1949
- Overall life expectancy: 68 years
- Women: 70.7 years
- Men: 65.2 years
1949 marked a significant milestone: for the first time, women’s life expectancy surpassed 70 years. This gap between men’s and women’s life expectancy has persisted to this day, with multiple factors contributing to it, such as:
- Men engage in riskier behaviors like smoking and substance abuse at higher rates.
- Women tend to prioritize preventative healthcare more than men.
- Biological differences that may make women more resilient to certain diseases.

2010s: A Shift in Trends
The 2010s marked a turning point in US life expectancy trends. After decades of steady increase, life expectancy began to stagnate and even decline in some years. Here’s a look at how life expectancy unfolded in this decade:
- 2011: Overall life expectancy remained at 78.6 years. The breakdown was 81.4 years for women and 75.8 years for men. The ongoing opioid epidemic likely began to have a noticeable impact on mortality rates, particularly among younger adults.
- 2012: Overall life expectancy dipped slightly to 78.5 years. The breakdown was 81.3 years for women and 75.7 years for men. This could be due to factors like an increase in deaths from heart disease or a rise in suicides.
- 2013: Life expectancy remained flat at 78.5 years overall. The breakdown was 81.3 years for women and 75.7 years for men. Public health efforts to combat antibiotic resistance may have slowed the spread of some infections.

- 2016: Overall life expectancy remained flat at 78.6 years. The breakdown was 81.4 years for women and 75.9 years for men. The continued opioid epidemic and a rise in drug overdose deaths likely played a significant role in stalling life expectancy gains.
- 2017: Overall life expectancy declined to 78.6 years, matching the figure from 2010. The breakdown was 81.2 years for women and 76.0 years for men. This marked the first time in decades that life expectancy had declined for two years in a row. Public health officials expressed concern about this trend and began investigating the contributing factors.
Looking Ahead
The reasons behind the decline in life expectancy in the 2010s are complex and multifaceted. Experts point to a number of potential contributors, including:
- The opioid epidemic
- Increased deaths from chronic diseases like heart disease, diabetes, and COPD
- An aging population with a higher risk of health problems
- Social determinants of health, such as poverty, lack of access to health care, and unhealthy behaviors
Understanding these factors is crucial for developing effective strategies to reverse the decline and improve life expectancy for all Americans.
