This study examines how the social environment of religious congregations a
ffects the spread of contraceptive use in developing contexts, using Mozamb
ique as a case study. Analysis of qualitative data collected in urban areas
of that country in 1998-99 and of the data from the 1997 Mozambique Demogr
aphic and Health Survey suggests that, in urban areas, the environment of m
ore socioculturally diverse and inclusive Roman Catholic and mission-based
Protestant congregations is more propitious to the spread and legitimizatio
n of modern contraception than the milieu of smaller, relatively homogeneou
s, independent churches. In rural areas, however sociocultural diversity wi
thin and across different religious denominations is minimal, and membershi
p in any formal congregation offers an advantage in contraceptive learning.
