Most experienced genealogists are aware that the average life expectancy of our relatives has increased over the years. Most of the increases can be attributed to major improvements in hygiene, medicine, and (in recent years) the decrease in the use of tobacco products. Sadly, in 2016 and 2017 the trend went in the opposite direction. Americans now have a slightly shorter life expectancy than they had three years ago and the trend is getting worse.
We are now seeing the longest sustained decline in expected life span at birth in a century, an appalling performance not seen in the United States since 1915 through 1918. That four-year period included World War I and a flu pandemic that killed 675,000 people in the United States and perhaps 50 million worldwide.
Americans could expect to live 78.6 years at birth in 2017, down a tenth of a year from the 2016 estimate, according to the CDC’s National Center for Health Statistics. Men could anticipate a life span of 76.1 years, down a tenth of a year from 2016. Life expectancy for women in 2017 was 81.1 years, unchanged from the previous year.
Major contributors to the decrease in life expectancy include deaths from overdoses of drugs sold on the street such as fentanyl and heroin, as well as prescription narcotics.
The long-time killers of Americans actually became less of a problem. Deaths from heart disease, the No. 1 killer of Americans, which had been declining until 2011, continued to level off. Deaths from cancer continued their long, steady, downward trend.
