Vienna model results. A) Heat map of Vienna of the observed arrivals in Austria for the four top diasporas in Austria. B) Heat map of the diaspora model estimates in Vienna. C) Heat map of the gravity model estimates in Vienna. D) Spider plots of the top four diasporas in Austria, where each section is one of Vienna’s 23 districts. The ratio between the modeled and the observed arrivals—the estimate ratio—is displayed for each district for both the gravity model in gray (GER) and the diaspora model in red (DER). Read More
