Teens nowadays seem to be more than willing to share everything that are happening to them on social media, but new Pew study shows that these kids were discovered to be unexpectedly extra concerned.

A report released by the Pew Research Center’s Internet and American Life Project on Thursday stated that most of the teens in the U.S., about 51 percent, opted not to install an app that asked to much personal information. One out of four teens uninstalled an app after realizing too much of their personal information that they didn’t want to give were asked.

It is also showed that when it comes to location tracking, there was a difference among the preference of boys and girls. The study revealed that 37 percent of boys used the tracking feature and 59 percent of girls turned off the tracking feature for an individual app and even for the entire phone.

When a 13-year old teen was asked if she ever worry about what kind of data applications are taking on her phone, she said that she always chose not to allow using her location. The same as the answer of a 13-year old boy with the same query except if it’s really necessary for the app.

On the other hand, a 13-year old boy answered the question differently. He said that he doesn’t feel worried at all. He usually punch in allow on everything because he thinks a lot of people does the same and that he will not be singled out.

A 19-year-old girl stated that she doesn’t think her identity will be revealed with just messages and photos on her phone. So it’s does not really matter.

Pew's survey was based on interviews conducted with 802 U.S. teenagers aged 12 to 17, along with their parents over the phone.
