The paper examines three aspects of demographic change and conjectures abou
t their wider impact on British society. Two features of fertility behaviou
r are highlighted. The first deals with ethnic Variations and the likely co
ntinuation of high fertility rates amongst women of South Asian origin. The
second involves the continued bifurcation between career women and those f
or whom motherhood remains a central life project. international migration
is also assessed and the contradictions within the 'Fortress Britain' strat
egy exposed. Britain will continue to receive migrants from overseas and Br
itish society will become increasingly multi-ethnic. The paper also examine
s the tensions between an increasingly ageing population and the developmen
t of increased ethnic and cultural diversity. The paper concludes with some
implications of these changes for the discipline of sociology itself.
