Census method: The census method is a one-time large-scale survey. This statistical investigation method is often used in specific situations, such as finding out important national conditions or countries.

Sampling survey method: as the name implies, it is to randomly select a part of all the investigated subjects for investigation, and estimate and infer all the subjects according to the investigation results.

Statistical report method: there are usually prescribed forms and contents, which are arranged from top to bottom according to specific time, so that the personnel participating in the survey can fill in or provide statistical data.

Focus survey: Focus survey is also a kind of incomplete survey. To put it simply, this method is to select some representative (key) units from many survey objects for investigation. Because the selection of survey objects is planned, the total number of signs is relatively high, which can more accurately reflect the overall situation.

Comprehensive analysis method: based on the existing statistical data, some technical means are adopted to obtain the means, and finally the results are evaluated.
