3. Religious Fertility vs. Religious
Decline
"One of the most central injunctions of virtually
all traditional religions is to strengthen the family,
to encourage people to have children, to
encourage women to stay home and raise
children, and to forbid abortion, divorce, or
anything that interferes with high rates of
reproduction. As a result of these two
interlocking trends, rich nations are becoming
more secular, but the world as a whole is
becoming more religious." (Norris and
Inglehart 2004: 22-23, emphasis added)
4. Hypothesis: a combination of higher
religious fertility and immigration will lead
to a growth in the religious population
(defined in terms of belief) that exceeds
the net loss of communicants through
religious apostasy.
5. Methods
• Source: EVS / WVS & ESS + ethnic
minority surveys
• Cohort Component Projection Parameters:
Fertility & Switching (i.e. religious decline
or revival) by age and sex, plus current
Age/Sex Structure of Religious and
Secular 'Populations'
• Mortality Rates assumed as standard

8. What About the Muslim World?
• The religious cleavage between Islamists and
Secular Nationalists/Socialists/Liberals is
Paramount
• Q: Will higher fertility endow Islamists (or
even the wider 'religious' population) with
political leverage into the future?
• Berman & Stepanyan (2003) find a significant
but modest link between Madrassa attendance
and fertility in four countries
• This study uses WVS 1999-2000 dataset on 7-
15 countries (depends on question)
• Aim is to determine parameters for population
projections

18. Conclusions: Fertility
• In Muslim developing countries, unlike other
developing countries, higher national religiosity
is associated with lower fertility and National
GDP per head has no impact on fertility
• Islamists in Muslim countries are more fertile;
some evidence for sharpened fertility effect in
more 'modern' contexts, i.e. cities, the educated
• But effect modest: Muslim Religious Fertility
Dynamics more like USA and Europe than Israel
• The growth of the religious population through
fertility is a long-term process, unlike Israel
19. Conclusions: Religiosity
• Younger, Educated are less religious and/or
Islamist, but effect is complex and there are
exceptions (18-24, university students)
• Urbanites more Islamist than rural population
• Higher education levels may modestly lower
Islamism, but urbanization may raise it.
Generational change will have little effect
• GDP per head unlikely to affect religiosity
• Nationalism and Islamism seem compatible
• All told, we should expect a distinct Muslim
trajectory of modernization and development
rather than secularism

and Islamist populations for Muslim world,
