Demographics of Poland
According to GUS, about 38,325,000 people live in Poland, however, the same report states that the number of residents living in the country all the time is approximately 37,200,000; with 1,125,000 people living abroad for 6 to 7 months or more. It means that the permanent population may be correspondingly smaller.
History of the Jews in Poland
The number of Jews immigrating to Poland from Ukraine and Soviet Russia during the interwar period grew rapidly. Jewish population in the area of former Congress of Poland increased sevenfold between 1816 and 1921, from around 213,000 to roughly 1,500,000. According to the Polish national census of 1921, there were 2,845,364 Jews living in the Second Polish Republic; but, by late 1938 that number had grown by over 16% to approximately 3,310,000. The average rate of permanent settlement was about 30,000 per annum. At the same time, every year around 100,000 Jews were passing through Poland in unofficial emigration overseas. Between the end of the Polish–Soviet War and late 1938, the Jewish population of the Republic had grown by over 464,000.
