Increasing religious diversity in Vienna, 1971–2011

Population by age, sex and religion

Forces shaping the religious composition

Religious net mobility
Catholic and Protestant Churches have been losing members in a similar way, but at a different scale. Most of the Catholic peak losses correspond to church-related scandals. Those exits resulted in an increasing share of people with no religious denomination. Statistics on religious mobility for Orthodox and Muslims are not available.

Net migration by religion
Net migration of Catholics, Protestants and people without a religious denomination fluctuated or stagnated between 1971 and 2011. Steady immigration of Orthodox, Muslims and other religions fostered the diversification of the religious landscape of Vienna. Since around 2000, Orthodox and Muslim net migration decreased while there was a further increase in immigration from other religions.

Total fertility rate by religion
In Vienna, the general level of fertility is relatively low and rather steady. Differentiated by religion, only Muslim fertility is still significantly above the demographic replacement level (of roughly 2.1 children per women), but is strongly converging towards the relatively low levels of other religious groups.

Interreligious marriages
The religion of children born into interreligious families is an important factor of the future religious composition of Vienna. Protestants have the highest rates of interreligious marriages. While there was an increase of exogamy among Catholics, the share of interreligious marriages among Muslims and secular people decreased. Statistics on marriages of Orthodox and other religions are not available.
