Life Expectancy in the Year You Were Born

U.S. life expectancy continues to shorten — dropping by more than seven months in 2021, according to data from the Centers for Disease Control and Prevention. Life expectancy for U.S.-born children is now 76.4 years, its lowest point in nearly two decades. Deaths caused by drug overdoses and COVID-19 infections were key contributors to the decline, the CDC data showed. COVID-19 took nearly 417,000 lives in 2021 — more than in 2020 — and for the second year was the third leading cause of deaths.

This week, Food and Drug Administration chief Dr. Robert Califf also noted another reason why U.S. life expectancy is lagging behind other high-income countries' figures: medical misinformation on the internet, something he said he aims to root out. 

If you're wondering what life expectancy was the year you were born and how it’s changed, the numbers going back to 1940 tell the tale.

The United States began the ’40s on an upswing, with life expectancy up sharply from 58.5 years in 1936, when the nation was still struggling with the economic devastation of the Great Depression. The ’40s would also bring significant public-health landmarks, including the mass production of penicillin and the DTP shot, which combined the pertussis, diphtheria, and tetanus vaccines.

Life expectancy dropped almost three years from 1942 to 1943. Though World War II may have driven a decline, a change in how life expectancy was calculated beginning in 1948 may have made the drop look more dramatic than it really was, scholars say.

1949 marked the first year women’s life expectancy eclipsed 70 — a milestone men would not reach for another three decades. Experts have long documented that women tend to outlive men, attributing the difference to several factors. Among them: Men take more risks, are less likely to seek medical care, and are more likely to die of heart disease and suicide. 1949 was also the last time the U.S. saw an outbreak of smallpox.

Life expectancy was relatively flat in the ’60s, rising less than a year from 1960 to 1970. Women added about 18 months to their lifespans, while men added only half a year. The ’60s also brought three significant vaccines against measles, mumps, and rubella, which were eventually combined into the MMR shot in 1971.

On average in 2021, life expectancy for men fell quicker than women, widening a gap that had been growing over the past decade. The CDC also noted that white people saw more deaths from COVID-19 in the second year of the pandemic than any other racial or ethnic group in the U.S. The increased mortality rate resulted in white people experiencing the second-biggest decline in life expectancy.
