In the 1984 edition of the Britannica, Bigordans are still shown as a separate ethnic group on the map "Primary European Ethnic Culture Areas". However this same map still shows Silesia and East Prussia as inhabited by Germans, as well as the Sudetenland. Since these areas had mass deportations of their German population after the Second World War, it is evident that the map does not reflect the reality of ethnic concentrations in Europe for any year after 1945.
