Polyethnic societies present some key implications for planners. Discrimina
tion against, and harassment of, minorities is worryingly universal, and pl
anning professions in ail societies need to recognize and address these iss
ues. Planning practice needs to reflect an awareness of the implications of
difference while incorporating an understanding of processes of social cha
nge in relation to minority and migrant groups, specifically, changes in ho
usehold size and/or structure and orientation toward the housing marker. Th
e core empirical data of the paper comes from the 1991 Census of Population
and a major study of housing needs in a large district in northern England
. Although focused substantively on British debates and data, most of the c
oncerns addressed in this paper have an element of universality.
