The authors investigated 457 children's orbits after school in four specific school districts by using the Global Positioning System (GPS). The purpose of this paper is to clarify the children's home range in relation to their school districts' characteristics by analyzing the spacio-temporal distribution of their staying points. In the result, the children living in the urban district tends to travel on foot or by bicycle within the range from 250 to 1,000 meters from their home, at the same time the children living in the suburban districts tends to travel within the range from 50 to 250 meters and also further than 1,000 meters. There was a correlation between elementary schooler's home range and school districts' features.
