Census, also known as national survey, is an important tool for modern statistics of the national population. It investigates the national population, housing and related important matters in a concrete and comprehensive way. Since 1790, when the U.S. government launched the first census with modern significance, social concepts such as suicide rate, crime rate, religious distribution and the ratio of men to women have emerged, which still affect the operation of modern countries economically and politically.

The earliest census in China was conducted in the second year of Emperor Hanping in the Western Han Dynasty (AD 2), with data of12,366,470 households, 57,676,5438+0,406,5438+0 people.
