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.

World War II casualties of Poland
An estimated 50,000 to 100,000 ethnic Poles were killed in an ethnic cleansing operation carried out by the Ukrainian Insurgent Army (UPA) beginning in March 1943 and lasting until the end of 1944 in the Nazi occupied Volhynia and Eastern Galicia. The Institute of National Remembrance maintains that 7,500 ethnic Ukrainians were also killed during this interethnic conflict The figure of 5.6 to 5.8 million war dead estimated by the IPN was for only the Jewish and ethnic Polish population. They did not provide figures for the death toll of Polish citizens from the other ethnic minorities.According to the figures published by the Polish government in exile in 1941 there were about 7.0 million Polish citizens from ethnic minorities at the beginning of the war in September 1939, mostly Ukrainians, Belarusians, Polishchuks and Lithuanians living in the eastern regions of Poland annexed by the USSR. The IPN did not estimate the death toll of Polish citizens from these ethnic minorities. The IPN maintains that accurate figures for these losses are not available because of border changes and population transfers, according to their figures 308,000 Polish citizens from the ethnic minorities were deported into the interior of the Soviet Union and were conscripted into the Soviet armed forces. During the German occupation Polish citizens from ethnic minorities were deported to Germany for forced labor.In prewar Poland about 800,000 persons were identified as ethnic Germans. According to the IPN 5,437 ethnic Germans were killed in the 1939 military campaign. The IPN also puts the number of Polish citizens conscripted into the German armed forces at 250,000 of whom 60,000 were killed in action. Tens of thousands of ethnic Germans were killed during the Nazi evacuation from Poland in 1944 and 1945, and as a result of repression NKVD and Red Army or died in post war internment camps. During the war the Nazi occupiers instituted the Volksliste in the Polish areas annexed by Nazi Germany to register ethnic Germans in Poland. Many Polish citizens were pressured to sign the Volksliste in order to avoid Nazi reprisals. About 1 million persons were on Volksliste groups 1 and 2 that included Polish citizens of German descent; Volksliste groups 3 and 4 included 1.7 Polish citizens that were subject to future Germanisation. In addition 61,000 . ethnic Germans were living in the General Government. During the war 522,149 ethnic Germans from other nations were settled in Poland by the Third Reich. By 1950 670,000 ethnic Germans from prewar Poland had fled or were expelled and about 40,000 remained in Poland; about 200,000 Polish citizens who were on Volksliste groups 1 and 2 during the war were rehabilitated as Polish citizens.
