The life expectansy in the US is 78.69 years (2016).
December 10, 2018 04:02 pm Michael Devitt – A century ago, the average life expectancy in the United States was just 39 years.(budgetmodel.wharton.upenn.edu) Admittedly, that figure is something of an outlier, given the deadly influenza pandemic that raged that year, killing an estimated 50 million people or more around the globe,(www.cdc.gov) including some 675,000 Americans. The years immediately before and after the so-called Spanish flu wreaked havoc worldwide saw life expectancies of 51 and 55 years, respectively.
As a result of overall increases in mortality rates, average life expectancy decreased to 78.6 years in 2017.

Still, it's notable that a person born in the United States today can expect to live decades longer than those in generations past -- to more than age 78, according to the CDC.
