The Igboland of Nigeria has been under the influence of socio-economic
change since the tum of the century, as typified by a high literarcy
rate, a highly migratory population, the predominance of Christianity,
and built-up towns and villages. Yet Igbo fertility has remained high
even by Nigerian standards. Part of the explanation for high Igbo fer
tility is the prevalence of peculiar socio-cultural institutions which
tend to encourage or support high fertility. In this study fertility
differentials, reproductive behaviour and fertility preferences and in
tentions are examined as a function of three well-recognised cultural
institutions or contextual factors: the bestowal of high fertility hon
our or title to women of a given family size, patriarchal relations, a
nd patrilinearity and son preference, together with individual status
indicators. Our findings suggest that socio-cultural institutions esta
blish or condition relationships and behaviours among the Igbo; in oth
er words, individual fertility behaviour takes place within the contex
t of complex social organisation and under the influence of multiple s
ocial, cultural and ideological realities.
