One in five teenage girls has experienced depression in the past year, which is twice the rate of 2011.
13% of white and Hispanic teenagers and 9.5% of black teenagers experienced a major depressive episode last year.
If we take it by age category, 19% of 16- to 17-year-olds experienced a major depressive episode last year.
These are massive increases over the 2011 numbers, and they persist into young adulthood. The rates of major depression for 18- to 25-year-olds stood firmly at 8% for 10 years. They started to climb in 2013 and are now at 14%.
The data is from the 2018 National Survey on Drug Use and Health.
Unfortunately, the survey makes the common mistake of questioning teens and not their parents. I have no doubt that including the parents in the survey and asking them about their mental health would be very revealing.
