Understanding of Population Difference between Railway Lines in Tokyo Metropolitan Area

Abstract

This study illustrates the characteristics of population migration along railways in Tokyo Metropolitan Area in recent years. Using OD data of population movement of each line, it was identified that the population movement, net migration, and migration of men and women differed between the lines. In addition, it was founded that the difference in facility location, housing type, land prices, preference as a place of residence, etc. are the factors that affect migration. Japan is the world's fastest aging country, and it is said that aging will reduce railway demand. Urban railway companies also hope that more young people live in the area along their railway since an aging society makes a negative impact on not only the revenue from passengers but also the revenue from the related businesses along the urban railway lines such as housing, commercial facilities, entertainment facilities and so on.
