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 Poland (1945–1989)
Before World War II, a third of Poland's population was composed of ethnic minorities. Poland had about 35 million inhabitants in 1939, but fewer than 24 million in 1946, within the respective borders. Of the remaining population over three million were ethnic minorities, such as Germans, Ukrainians and Jews, most of whom would soon leave Poland. Poland suffered the heaviest proportionate human losses during World War II, amounting to 16–17 percent of its population. It is estimated that up to 6 million Polish citizens died from war-related causes between 1939 and 1945. The approximate figure includes 3 million Jewish-Polish victims as part of the above total. The number of ethnically Polish victims was perhaps 2 million.
