This paper explores an emerging common phenomenon of new immigrant groups clustering in suburban areas. We argue that the households of new immigrant groups are concerned with neighborhood safety. They are attracted to suburban neighborhoods which generally have lower crime rates. Since suburban neighborhoods have become more heterogeneous, households of new immigrant groups can look for safer neighborhoods in the suburbs without necessarily paying a higher housing cost than they would reside in the central city or in other neighborhoods in the same suburban context. With such budget constraints, only a limited number of suburban neighborhoods are available. Subsequently, these households spatially cluster in suburban areas. The 1996 Toronto census data in general confirms this picture.
