Americans are not living quite as long

Life expectancy in the U.S. dropped for the first time since 1993.

The life expectancy in the U.S. has dropped. Not by much, but it's the first time since 1993 that life expectancy took a dip. That's according to new data released by the Centers for Disease Control and Prevention.

Between 2014 and 2015, the number of years a person typically lives when from 78.9 years to 78.8 years. So it's just a matter of months.

Still, women are expected to live longer than men: 81.2 years versus 76.3.

The number of years you're expected to live after you reach age 65 didn't change, though. That's still 20.6 years for women and 18.0 years for men.

The 10 leading causes of death also stayed the same: heart disease, cancer, chronic lower respiratory diseases, unintentional injuries, stroke, Alzheimer’s disease, diabetes, influenza and pneumonia, kidney disease, and suicide. Those causes accounted for 74.2 percent of all deaths in the United States last year.

Just the age-adjusted death rates – deaths per 100,000 – increased for white men, white women, and black men. You can see the death rates and causes below:

The infant mortality was at 589.5 in 2015 – not a statistically significant change from 2014. The leading causes of death stayed the same there, too: congenital malformations, low birth weight, sudden infant death syndrome, maternal complications, and unintentional injuries.

One year does not form a trend.

What exactly caused a dip in the United States' life expectancy is not quite clear at this point. Doctors say it's not necessarily a cause for concern, though.

"One year does not form a trend," Dr. Jiaquan Xu, an epidemiologist with the CDC's National Center for Health Statistics, told CNN.

"We need more data. If you look back to 1993, it decreased but hasn't decreased again (until now). Hopefully, that's what we're seeing here," Dr. Xu said.

In Minnesota

While the CDC doesn't list specific data about Minnesotans in this report, MPR says the U.S. Census Bureau released some information this week.

It shows that Minnesotans are getting older. The median age is now 37.7. That's about about seven months older than the median age in the Census' 2010 report.

MPR says the median age would be significantly older if it wasn't for young immigrants and higher birth rates among various immigrant groups.
