According to new government data, birth rates among teenagers in the U.S. have decreased significantly in the past several years. The information, collected from the CDC's National Center for Health Statistics, shows that over the past two decades teen births have dropped a staggering 57 percent.

Births per 1,000 teenagers, ages 15 through 19, have been reduced by an estimated 4 million births, as reported on Philly.com Wednesday. Researchers said that these teen pregnancies saved around $12 billion for taxpayers just in 2010, as these births more often require the mothers to need food stamps, Medicaid and other assistance. A single child born to a teen parent costs an average of $1,700 in taxes per year until age 15, according to the CDC information released Wednesday.

Chief program officer of the National Campaign to Prevent Teen and Unplanned Pregnancy Bill Albert said this lowered statistic "leapt out" from the report.

"We know, for instance, that only about 40 percent of teen mothers ever graduate from high school," Albert said to Philly.com. "Translate that number -- 4 million fewer births -- into a much, much lower high school graduation rate, and think about the prospects for those young women in this day and age and in this economy. It's pretty sobering."

In state-by-state breakdowns, it appears the South and Southwest's rates are higher while the lowest birth rates occur in the Northeast. Statistics among racial and ethnic groups also widely range, with Hispanic teens having the highest rate of 46.3 per 1,000 teens and Asian or Pacific Islanders at the low end with only 9.7. Births for other demographics include 20.5 for white and 43.9 for black teens according to USA Today.

"Birth rates for Hispanic teens are higher than for other groups," demographer and the report's co-author Stephanie Ventura said. "Right now, even though they dropped a tremendous amount, they are still higher than other groups. At one time, rates for blacks were higher but now Hispanics are higher."

Historically, all groups still surpass the generations before them in lowering teen birth rates. In 1957, 96.3 per 1,000 teens had children compared to 2013 preliminary data revealing only 26.3 per 1,000 teens gave birth.
