日本居住区的人口变化

Population changes in residential clusters in Japan

摘要:

城市和农村地区的人口动态是不同的。了解导致当地人口变化的因素具有各种社会经济和政治影响。在本研究中,我们使用人口普查数据在日本,以审查2005年和2010年之间的住宅集群的人口增长的贡献者。该数据集覆盖日本全境,具有500 $\times$ 500 $\textrm{m}^2$的高空间分辨率,使我们能够利用统计分析来审查全国各地(城市和农村)的人口动态。我们发现,除了面积,人口密度和年龄,集群的形状和集群内的居民的空间分布显着相关的人口增长率的住宅集群。具体地说,如果集群是“圆形”的(给定面积),并且人口集中在集群的中心附近而不是外围,人口往往会增长。

英文摘要:

Population dynamics in urban and rural areas are different. Understanding factors that contribute to local population changes has various socioeconomic and political implications. In the present study, we use population census data in Japan to examine contributors to the population growth of residential clusters between years 2005 and 2010. The data set covers the entirety of Japan and has a high spatial resolution of 500$\times$500$\textrm{m}^2$, enabling us to examine population dynamics in various parts of the country (urban and rural) using statistical analysis. We found that, in addition to the area, population density, and age, the shape of the cluster and the spatial distribution of inhabitants within the cluster are significantly related to the population growth rate of a residential cluster. Specifically, the population tends to grow if the cluster is "round" shaped (given the area) and the population is concentrate near the center rather than periphery of the cluster.
