In this paper, I presented a method to weigh three archetype situations of people flows in order to express the actual people flows in a county level area as a linear combination of the three archetype situations, and applied the method for the analysis of the commuters’ flows and house movers’ flows. It has become clear that the importance of the areas for commutation has increased since 1990, and, compared with the commuters’flows, the house movers’ flows do not have a common trend. Under the condition that the number of commuters does not increase, the quality improvement of the pre-constructed roads in the area is important.
