China Happy City Laboratory, founded by Outlook Weekly, has launched an urban happiness index system based on big data, including nine first-level indicators and hundreds of second-level sub-indicators, such as employment index, residents' income index, quality of life index, ecological environment index, urban attractiveness index, public safety index, education index, traffic index and medical and health index.
With the technical support of Business Intelligence Laboratory of Baidu Research Institute, the index system has collected samples from more than 10 trillion related cities.
The happiness of a city refers to the citizens' sense of identity, belonging, stability and satisfaction with the city where they live, as well as the yearning and praise of the outside crowd. I think the happiness in my city is still quite high. After all, the Winter Olympics has just been held here, and people all over the world have always appreciated us, so I think the happiness of my city is more suitable for the people.
