During the 20th century, advances in medications and other treatments were responsible for dramatic increases in how long people lived. But deaths from drug overdoses, chronic liver disease, suicide, Alzheimer's and blood infections (septicemia) have all gone up, resulting in a shortened average life span.

Heart disease and cancer still kill most Americans, but they weren't the reason people are dying younger. In fact, deaths from heart disease have been declining. Between 2006 and 2016, however, death rates from from drug overdoses increased 72 percent and for suicides, 23 percent.
The CDC didn't say what is behind the declining life expectancy, but William Dietz, a disease prevention expert at George Washington University, told the AP he sees a sense of hopelessness.
“I really do believe that people are increasingly hopeless, and that that leads to drug use, it leads potentially to suicide,” he said.

The CDC statement also said:
- A baby born last year in the U.S. is expected to live about 78 years and 7 months, on average. An American born in 2015 or 2016 was expected to live about a month longer, and one born in 2014 about two months longer than that.
- The suicide rate was 14 deaths per 100,000 people. That's the highest since at least 1975.
- The percentage of suicides because of drug overdose has been inching downward.
- Deaths from flu and pneumonia rose by about 6 percent. The 2017-2018 flu season was one of the worst in more than a decade, and some of the deaths from early in that season appeared in the new death dates.
- West Virginia was once again the state with the highest rate of drug overdose deaths. The CDC did not release state rates for suicides.
- Death rates for heroin, methadone and prescription opioid painkillers were flat. But deaths from the powerful painkiller fentanyl and its close opioid cousins continued to soar in 2017.
So who lives longest? According to the report, Hispanics had the highest life expectancy at 81.8 years. Non-Hispanic whites were next, with 78.5 years, followed by non-Hispanic blacks, with 74.8 years.
Where you live can also affect how long you can expect to live.
Areas in the bottom 25 percent of the report had four things in common: Most of the people were less educated, low income and predominantly black, and they were in the South.
The Robert Wood Johnson Foundation, which worked with the CDC on the report, created a calculator to determine the life expectancy of an area.

The average life span for Georgians, according to the calculator, was 77.40 years. If you live in Gwinnett County, though, you get an extra 3.18 years. Cobb County residents are looking at 80.08 years on Earth, but those in DeKalb County get only 79.14.
The area with the lowest life expectancy in the U.S. was Stilwell, Oklahoma, where people averaged 56.3 years. Where do people live longest? Chatham, North Carolina. Residents of this higher-income area could expect to be around until they reach 97.5 years old.
