Austria Emigration and Immigration
Austrian emigration patterns have been difficult to determine. There was no state known as Austria until 1918; prior to then the sprawling Habsburg Empire, an amalgam of a dozen nationalities, encompassed the idea of Austria. Thus Austrian immigration can rightly be seen as the immigration of Czech, Polish, Hungarian, Slovenian, Serbian, and Croatian peoples as well as a plethora of other national and ethnic groups.
The Austrian Americans website provides a historical overview of immigration to America.
Sometimes it is possible to guess where an immigrant originated through surname distribution maps.
