As an important component of population statistics, the statistics on marriages have a tradition going back to the 18th century, in the sense of a systematic recording of marriages by the religious communities. Since 1945, they have been based on the reports of Austria’s registry offices intended for administrative purposes. From 2010, the reports on the establishment of registered partnerships were added. Since 1 November 2014, these reports have been automatically transmitted from the Central Civil Status Register to Statistics Austria. Since 2015, all marriages and registered partnerships of Austrian citizens with their main residence in Austria that took place abroad have also been recorded. The regional allocation of the published data is based on the place of residence of the first registered partner. If this place of residence is not located in Austria, the data is allocated according to the place of residence of the second registered partner.
