Languages


In the Austrian Empire (Cisleithania), the census of 1911 recorded Umgangssprache, everyday language. Jews and those using German in offices often stated German as their Umgangssprache, even when having a different Muttersprache. The Istro-Romanians were counted as Romanians.
In the Kingdom of Hungary (Transleithania), the 1910 census was based on mother tongue. According to the census, 54.4% of the inhabitants of Hungary were recorded to speak Hungarian as their native language. This number included the Jewish ethnic group (around 5% of the population) who were overwhelmingly Hungarian-speaking (the Jews tending to declare German as mother tongue due to the immigration of Jews of Yiddish/German mother tongue).
