A new study from the Substance Abuse and Mental Health Services Administration found more than one in ten children in the United States live with at least one alcoholic parent.
The agency looked at data from 2005 to 2010, found an average of 7.5 million children lived with a parent who abused alcohol.
That's about 10.5% of the U.S. population under 18.
The researchers also say the parents' drinking problems take a toll on their children, and can put them at greater risk for mental health issues like depression and anxiety.
After conducting the study, the agency is trying to promote alcohol abuse prevention and underage drinking.
