What is the meaning and development history of social statistics?

Social statistics is the essence of social science. Mathematician Descartes first put forward variables and studied variables, such as discrete variables and continuous variables. According to the authoritative statistical history, there have been "political arithmetic" and "national politics" since17th century, that is, primary social statistics, which originated in Britain and Germany. In other words, the formation of social statistics is two centuries earlier than that of mathematical statistics.

Because social statistics is widely used in political and economic fields, it can be used for both qualitative analysis and quantitative analysis, so it has been highly valued by successive governments in various countries and has been systematically developed.
