Teen births in the U.S. have it an all-time low with both the number of births and birth rate dropping by 10 percent in the last year, according to federal data released Thursday.

In 2013, there were 274,541 births from parents that were between the ages of 15 and 19 years old. The National Center for Health Statistics said 2013 saw the lowest amount of births since it started tracking teen birth rates 80 years ago.

According to USA Today, the all-time peak year for teen birth rates was in 1970 with 644,708 teen births.

The 10 percent decrease marked another historic low as teen births dropped from 29.4 per 1,000 in 2012 to 26.6 births per 1,000 in 2013, which was "quite dramatic," said Carl Haub, senior demographer of the nonprofit group Population Reference Bureau.

"A drop of 10 percent in a single year is quite dramatic," he said.

Haub, however, noted that although the rates have decreased in the U.S., the new low of 26.6 is still 5.5 times higher than the teen birth rate in Western Europe where they are only experiencing single digit rates.

According to the most United Nations data, Switzerland's teen birth rate is at an all time low of 1.9, and Luxembourg is at a high of 8.3. The rest of the Western European nations have reported rates in the area of 5 or 6 per 1,000 teens.

Chief program officer of the National Campaign to Prevent Teen and Unplanned Pregnancy Bill Albert said the decrease "has gone from extraordinary to almost unbelievable."

Albert attributed the decline in teen birth rates to teens practicing safer sex with the use of contraception.

"The historic decline has been driven by the magic formula of less sex and more contraception," Albert said.

He also said the organization added the "And Unplanned Pregnancy" to the name in 2007 as a way of educating young adult singles after "teen pregnancy was plummeting."

According to USA Today, the most recent U.S. data was based on birth certificates that reflected declines in birth rates for all ages with the exception of parents in their 30s and 40s, which slightly increased in 2013.

Preliminary reports of the birth rate in 2013 have shown an increase since 2012 with 3,957,577 births -- 4,736 more than the previous year.
