Abstract

Religious affiliation is nowadays getting plenty of attention in Austria, in the public spherewith increased presence in the news and in the policy discourse. The aim of this study is toestimate the religious composition of the population of Vorarlberg in 2018, takingadvantage of available data, such as census information and statistics on components ofpopulation change. The latest census that collected data on religion was implemented in2001 and since then population counts have been relying on register data and did not collectdata on the religious affiliation of the Austrian population. Therefore, to study changes inthe religious composition of the population residing in Vorarlberg, it needs to be estimatedusing population projections following a methodology that was developed by Goujon et al.(2017) in a project to reconstruct (and project into the future) the population of Austria andVienna in 2016. The reconstruction shows that Vorarlberg follows similar trends as thoseobserved in Austria since 2001: 1) The share of Roman Catholics declines strongly, 2) thereis a strong increase in the population with no religious affiliation, and 3) the share ofMuslims has increased substantially which is the outcome of two main trends – fertility andmigration. The study of the origin (country of birth) of Muslims residing in Vorarlberg in2018 points at an increasing Austrian-born population, originating from parents or grandparentsborn predominantly in Turkey but also at a diversification as a result of the 2015refugee crisis.
