Development of Commercial Accumulation Statistics Throughout Japan and Utilization Environment of Them

We developed a new spatial dataset called “Commercial Accumulation Statistics”. It includes polygon data which represent location, shape, and scale (the number of shops) of commercial areas throughout Japan. First, we developed environment of data development of the Commercial Accumulation Statistics, and completed data development of the entire Japan. Secondly, we verified the reliability through cross-checking with existing statistical data. It led to a conclusion that the data is consistent enough with the existing statistics to monitor the distributions and scales of commercial areas in all prefectures. Finally, data delivery environment was developed to allow researchers to use it for research purposes.
