The index is divided into individual index and total index according to the different scope of phenomena reflected. Index, or statistical index, is an important statistical method for analyzing quantitative changes in social and economic phenomena. It originated in the second half of the 18th century, when gold and silver mined in the New World of America continued to flow into Europe, causing prices in Europe to rise suddenly, arousing widespread social concern. In order to measure changes in prices, economists began to try to compile price indexes.

The index is a relative number that indicates the dynamics of socio-economic phenomena. The index can be used to measure the overall dynamics of socio-economic phenomena that cannot be directly added and cannot be directly compared; it can analyze various factors in the total changes in socio-economic phenomena.
