Abstract: In this paper, we develop high frequency indexes to measure sales in service industries and production activity in the manufacturing industry by using GPS mobility data from mobile applications. First, focusing on the possibility that the number of customers in service industries can be estimated using mobility data, we develop indicators to capture economic activity in amusement parks, shopping centers, and food services. We show that using GPS mobility data, it is possible to nowcast economic activity in the service industries, in real time, with a high level of precision---something which conventional statistics are largely unable to assist. In addition, by using statistical methods such as clustering, we can construct an indicator with even better nowcasting performance. Second, in the manufacturing sector we identify the locations of relatively large factories using panel data from the Economic Census for Business Activity and by utilizing hourly and daily mobility patterns such as a daytime ratio. We then construct indicators for nowcasting production based on the population in the specified areas. We find that we can nowcast production with a high level of precision for some labor-intensive industries including the transportation equipment and production machinery industries. These results suggest that mobility data are a useful tool for nowcasting macroeconomic activity in a timely manner.
