What kind of city do you want to live in? A city that is old and traditional, or one that is young and energetic?
On May 4, Tencent Big Data released a report on the “youth index” of cities in China. The index was based on users of Tencent’s instant-messaging app, QQ, aged between 16-35 years old. It was calculated (计算) using differences in the population of young people within each city.
