“Powerpuff Girls” survey shows girls prefer sports, video games and other non-stereotypical activities.

A U.K. survey of girls ages 7 to 15, conducted to mark the return of Cartoon Network's  “The Powerpuff Girls,” has revealed that girls are ignoring stereotypes and are tougher than ever before.

“The Powerpuff Girls” premiered in the U.K. on Cartoon Network last night and will air every weekday night.

Findings of the study include:

Additionally, when asked what qualities girls should have, 28 percent said they should be tough, 46 percent said they should be strong and 60 percent said they should be clever. Meanwhile, 8 percent of boys agree that girls should be tough while 48 percent thought girls should be pretty and 31 percent thought they should be cute.

On average, 23 percent of boys thought they were “worth” more than girls, whereas fewer than 5 percent of girls agreed with that statement. However, on average, once girls hit the ages 14-15, their perception of themselves dropped dramatically with triple the number agreeing that boys were worth more.

“I remember when I was 15 and having all kinds of crazy things going on in my brain. As a young girl, that age can be a time of self-doubt, a time where you let your insecurities show, a time where you're basically just a bit unsure. Strong role models are super important during those phases of anyone's life. ‘The Powerpuff Girls’ are 100 percent the strongest and coolest kind of role models to have around,” says Charli XCX, musician and ambassador for “The Powerpuff Girls.” “The show flips gender stereotypes on its head and is accessible and fun for kids but also for people my age. I used to love it when I was younger, but I feel like I'm even more obsessed with it now. I see myself in the characters for sure! As all girls should. Strong, fierce, sassy and cute are all the best ways to be, and we all have that deep down inside us even if we don't quite realize it yet.”
