In anticipation of Czechoslovakia's 1930 population census, one observer, writing in the Zionist Jüdische Volksstimme, assessed the importance of this statistical event for the Jewish nationalist movement:
To us the upcoming census is more than merely a way to obtain reliable data about changes and demographic developments among the Jewish people. We are anticipating an increase in the number of Jews choosing “Jewish nationality,” and thus for us the census, much more so than for other peoples in this state, is an event of national importance […] once the Jewish public becomes aware of the significance of the census, it will be pointless for the other nationalities to attempt to restore their own ranks by decimating the Jewish nation in Czechoslovakia.
