人口普查是获得人口资料的最基本的方法,也是现在世界各国所广泛采用的搜集人口资料的方法之一。人口普查就是收集、汇总、评价、分析、发布一个国家或地区在某一特定的标准时点所有人口以及与人口相关的社会数据的全过程。由于人口普查资料能为国家提供某一时点的准确人口数字,近年来世界各国都依靠定期进行人口普查来掌握全国人口数字。 Census is the most basic method of obtaining population information and is one of the methods widely used by all countries in the world to collect population information. Census is the collection, aggregation, evaluation, analysis, release of a country or region at a particular standard point of all population and population-related social data throughout the process. Since census data provide the country with an accurate population at a certain point in time, all countries in the world rely on periodic censuses to grasp the national population in recent years.
