A new study from the Centers for Disease Control and Prevention shows that nearly one in four women are sexually assaulted in their lifetimes.

The study, released Tuesday, is the first to look at sexual assault and abuse in the context of race, ethnicity, income and education.

The findings will not only inform how we respond to and address this epidemic, they will help guide our public policy efforts and help us better serve those most at risk, CDC Director Dr. Tom Frieden said in a statement.

The CDC found that in 2015, nearly 6% of women reported having been sexually assaulted or raped in the previous year.

The findings were released as the CDC released its National Violence Against Women Survey, which found that about 14.6% of American women had been sexually victimized in the prior year.

Of the 6.6 million women who responded to the survey, 6.3% reported being raped or sexually assaulted, according to the CDC.

That number was up from 6.2% in 2015.
