广岛市未来人口预测数据（2010-2040）

广岛市是日本广岛县的首府。1889年4月1日广岛正式确立为一个城市。此后，广岛市人口不断增加。二战时，人口锐减。之后，人口又恢复增长。预测广岛市未来人口数量对于社会经济发展、制定相关政策等具有重要意义。广岛市未来人口数据是在人口基准数据（2010年）基础上，运用日本国家社会保障人口问题研究所采用的队列因素法进行人口预测的。结果表明，广岛市未来总人口的数量趋于减少。广岛市不仅要面对人口老龄化问题，同时还要面对出生率下降问题。该数据集包括广岛市的行政界限数据、预测的2010- 2040年广岛市儿童（年龄在15岁以下）人口数量、老年（年龄在65岁以上，包括65岁）人口数量和总人口数量。该数据集以.kmz 和.shp 格式存储，压缩后数据量为1.68 MB。

Hiroshima City is the capital of Hiroshima Prefecture, Japan. It was officially established as a city on April 1, 1889. Since then, the population of Hiroshima City continued to grow, but dropped sharply during World War II before resuming its growth thereafter. Forecasting the future population of Hiroshima City is of great significance for socio-economic development and the formulation of relevant policies. The future population data of Hiroshima City was generated using the cohort-component method adopted by the Japan National Institute of Population and Social Security Research, based on the 2010 population baseline data. The results show that the total future population of Hiroshima City tends to decline. Hiroshima City is facing not only the problem of population aging, but also the decline in birth rate. This dataset includes the administrative boundary data of Hiroshima City, as well as the forecasted population figures for children (under 15 years old), the elderly (65 years old and above, including 65 years old) and the total population of Hiroshima City from 2010 to 2040. This dataset is stored in .kmz and .shp formats, with a compressed size of 1.68 MB.
