Abstract
The populations of Javanese cities have grown mainly due to the inflow of migrants from the rural areas, as well as by natural increase. Behind this inflow, there is an overpopulation of laborers in the rural areas. However, there are also migrants from other urban areas. Actual movement cannot be fully understood solely in terms of the escape from poverty that it offers.
Many studies have been made about migrants who work for the informal sector, because various social problems are concentrated in the poor class. This article aims to compare the background and characteristics of movement between laborers in the informal sector (housemaids) and laborers in the formal sector (factory laborers in a Japan-Indonesia joint venture), also between migrants from rural areas and migrants from urban areas. This comparison makes it possible to see the inflow of migrants to urban areas as a whole, and gives some indication of what efforts migrants make to live through a difficult period.
