Mobile spatial statistics is a new form of demographic statistics that can track “when” and “what kind of person” moved from “where” to “where”

New demographic statistics

“Extrapolation” that estimates population based on no. of devices

Operation data*3 of : Users in Japan: Approx. 80 mil units *1 Foreigners visiting Japan: Approx. 12 mil units *2

*1: Estimation is performed based on these units after eliminating the no. of enterprise and MVNO accounts, etc. (As of March 2020) *2: Actual no. of visitors for 2019 *3: Data required to maintain mobile phones connectible all the time
