Crimes such as youth stealing and drunk driving are drastically reduced, why?

In Australia, criminal activity by juveniles has been confirmed to decrease sharply, such as halving in the last 10 years. The cause seems surprisingly "Internet".

Dr. Jason Pine's research team at the Australian National University (ANU) compared and analyzed the crime rate from 10 to 21 years of age born in New South Wales in 1994 and born in 1984. As a result, it became clear that the crime rate has decreased greatly, such as violent crime by 39%, drug crime by 22%, general theft by 59%, vehicle theft by 59%, drunk driving down by 49%, etc. It was.

Dr. Pine considers the cause of the decrease in the crime rate to be "a change in the lifestyle habits of young people". Specifically, with the spread and development of the Internet in recent years, as time spent on social networks and on-line media increases, the time that young people hang out in town is drastically reduced. Researchers think that parents and teachers may not be able to reach their eyes and opportunities to hang out in a group on a street where impulsive 'anger' tends to occur is reduced, so that opportunities for crime may be reduced.


However, Dr. Pine points out that decreasing the crime rate is not pleased with deliberation. That is because traditional criminal acts such as theft have decreased, new criminal acts abusing the Internet are appearing.

In addition, it is also confirmed that the number of chronic offenders who repeat the crime repeatedly increases by 5%, while the crime rate has decreased overall. As such, while the percentage of people committing crimes for the first time in New South Wales is decreasing, "hard core" young people who are still repeating the crime are still considered to remain.
