Distribution of the German language in Austria-Hungary in 1910
Ethno-linguistic map of Austria-Hungary, 1910. (Rusyns are registered as Ukrainians)

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).
