Jewish population distribution by region 1170
These figures are based on the records of Benjamin of Tudela, a Jewish traveller from the Middle Ages who provided one of the most comprehensive collections of population statistics from the period. Benjamin's writings not only recorded the number of Jews living across this part of the world, but also gave an insight into societal structures and the ordinary daily lives within Jewish communities in the medieval period. The source providing these figures, however, has adjusted some of the statistics to account for known populations that were missing from Benjamin of Tudela's records, especially in Europe and Asia.
