China's Population Development,Changes and Current Situation,Reference to Data of the Seventh Population Census

重点针对2020年第七次全国人口普查主要数据,结合自1953年起历次人口普查数据,从人口数量、人口变动、分省人口分布、人口年龄结构和老龄化、人口城镇化、人户分离和流动人口,以及出生性别比、受教育程度、港澳台和外籍人口状况等几个方面进行比较分析,描述中国人口发展现状和变化。除此之外,结合官方刚刚公布的2011到2019年数据,分析了从2010年到2020年这十年的人口数量,以及出生率、死亡率、自然增长率和总和生育率的变化情况,并将调整后的结果与调整前的结果进行了比较,重点分析了"单独二孩"和"普遍二孩"政策调整前后出生人数和总和生育率的变化。

Using the data from Seventh Population Census in 2020,combining the data from former censuses,we analyze the total population,populaton dynamic,provincial population distri-bution,age structure and aging,urbanization,separation and floating population,as well as sex ratio at birth,educational status,and population from out of mainland,and portray population development and changes.In addition,the government just published the adjusted population data from 2011 to 2019,and we discuss the increase of total population and the change of birth rate,death rat,and increase rate,as well as total fertility rate,and compare the differences between adjusted and unadjusted results within the ten years.The changes of the number of births and total fertility rates around the time of the release of fertility policies are focused.
