中国各城市栅格层面人口分布数据

人口分布是指人口在一定时间内的空间存在形式、分布状况，包括各类地区总人口的分布，以及某些特定人口（如城市人口、特定的人口过程和构成（如迁移、性别等））的分布等。人口分布是受自然、社会、经济和政治等多种因素作用的结果。自然环境条件也（如纬度、海拔、距海远近等）对人口分布起重要作用。 20世纪以来，随世界范围的工业化和城市化进程的加速，社会、经济和政治等因素对人口分布的影响越来越大，越来越多的经济学家对人口与经济相互关系进行探讨，形成了专门的人口经济学。Population distribution refers to the spatial existence forms and distribution status of a population within a given time period, covering the distribution of the total population across various regions, as well as the distribution of specific demographic groups (e.g., urban populations) and specific demographic processes and compositions (e.g., migration, gender structure). Population distribution is the outcome of the combined effects of multiple factors including natural, social, economic, and political elements. Natural environmental conditions, such as latitude, altitude, and distance to the sea, also exert a significant impact on population distribution. Since the 20th century, with the accelerating pace of global industrialization and urbanization, the influence of social, economic, and political factors on population distribution has grown increasingly pronounced. An increasing number of economists have conducted research on the interrelationship between population and the economy, leading to the establishment of the specialized academic discipline of population economics.
