Geburtenbarometer Vienna aims to provide an up-to-date monitoring of fertility in Vienna,
based on a set of annual and quarterly indicators of fertility rates and regularly published
summary reports. This paper gives an overview of the data, methods and indicators used and
contrasts main results with the data for other Austrian regions and for the whole country.
Throughout much of the 20th century, Vienna recorded fertility rates deep below those in
other parts of Austria. Because fertility in Vienna differs markedly between Austrian-born
and foreign-born women, our study looks at these fertility differentials and their influence on
the overall fertility patterns for Vienna and Austria. Migrant women in Vienna not only had a
rapidly increasing share on total births since the mid-1980s and thus contributed to a gradual
increase in the absolute number of births in the city, but their higher fertility has also helped
to push period fertility rates in Vienna towards the levels recorded in other regions of Austria.
Our study brings to light the distinct population dynamics in Vienna, where high childlessness
and low fertility are combined with a positive balance between births and deaths and
sustained population growth and where the population trends are strongly influenced by the
direct and indirect effects of migration.
