Note 113 — Chapter VI · THE AREA OF POLISH SPEECH

The Jews cluster especially in the eastern governments of Warsaw, Lomsha and Siedlez, where their percentage varies between 15.6 and 16.4. This ratio is lower in the southern and western administrative divisions. In Kalish it reaches only 7.2 per cent and is reduced to 6.3 per cent in Petrokow. In the cities the Jews constitute on an average slightly over a third of the population, although here again they are more numerous in the east. Cf. D. Aïtoff: Peuples et langues de la Russie, Ann. de Géogr., Vol. 15, May 1909, pp. 9-25.
