统计的作用是给社会提供信息。要有这产出,先得有相应的投入,欲予,得先取,世道如此,像政府想为人民服务,就得先收税,一个理儿。统计调查就是统计的一种投入,要从调查所涉及的范围来说,无非全面调查和非全面调查两大类。 The function of statistics is to provide information to the community. If we want to have this output, we must first make the appropriate investments, give priority to, and take the lead. If the government wants to serve the people, it must first collect taxes and act as a reasonable child. Statistical survey is an investment in statistics, from the scope of the investigation, no more than a comprehensive investigation and non-comprehensive investigation of two categories.
