人口数据库

人口数据库是中国疾病预防控制中心建立的全国性人口数据资源，收集了自2004年以来全国至县级的常住人口数和户籍人口数，包括分性别和年龄组的人口数据。该数据库是在国家统计局发布的人口数据基础上，由各省核对调整后确定，并由中国疾病预防控制中心和省级疾控中心系统管理员统一维护。The Population Database is a national-level population data resource established by the Chinese Center for Disease Control and Prevention (China CDC). It collects data on resident population and household registered population at the national to county levels since 2004, including population data disaggregated by gender and age groups. This database is finalized through verification and adjustment by each provincial authority based on the population data released by the National Bureau of Statistics of China, and is uniformly maintained by the system administrators of China CDC and provincial Centers for Disease Control and Prevention.
