Partitions (1795–1918)

By the First Partition in 1772, the Polish–Lithuanian Commonwealth lost about 211 000 km2 (30% of its territory, amounting at that time to about 733 000 km2), with a population of over four to five million people (about a third of its population of 14 million before the partitions). After the Second Partition, Commonwealth lost about 307 000 km2, being reduced to 223 000 km2. Only about 4 million people remained in Poland at that time, which makes for a loss of another third of its original population, about a half of the remaining. After the Third Partition, overall, Austria had gained about 18 percent of the former Commonwealth territory (130,000 km2) and about 32 percent of the population (3.85 million people). Prussia had gained about 20 percent of the former Commonwealth territory 149,000 km2) and about 23 percent of the population (2.6 million people). Russia had gained about 62 percent of the former Commonwealth territory (462,000 km2) and about 45 percent of the population (3.5 million people).

is a disputed topic, Tadeusz Piotrowski maintains that the 1931 Polish census "involved questionable methodology, especially the use of mother tongue as an indicator of nationality", noting that it had underestimated the number of non-Poles. The official figures for nationality from the 1931 Polish census based on the mother tongue put the percentage of ethnic Poles at 68.9%, Jews 8.6% and other minority groups 22.5%. Piotrowski cited a study by the Polish historian Jerzy Tomaszewski that puts that the adjusted census figures (taking religious affiliation into account) of ethnic Poles at 64.7%, Jews 9.8% and other minority groups 25.5% of Poland's population. Polish demographer Piotr Eberhardt maintains that it is commonly agreed that the criterion of declared language to classify ethnic groups led to an overestimation of the number of Poles in pre-war Poland. He notes that in general, the numbers declaring a particular language do not mesh with the numbers declaring the corresponding nationality. Members of ethnic minority groups believe that the language criterion led to an overestimation of Poles. The detailed figures for the census published by the Polish government provided a breakdown by religion for the various language groups, the details of the Polish census of 1931 published by the Central Statistical Office the Polish Republic according to language and religion are as follows.: Breakdown of Total 1931 Polish Population by Language and Religion Figures may not add due to omitted answers and those not practicing or declaring a religion.

Poles-The Institute of National Remembrance (IPN) figure for deaths of Poles due to the German occupation is 2,770,000. This figure includes "Direct War Losses" -543,000; "Murdered in Camps and in Pacification" -506,000; "Deaths in prisons and Camps" 1,146,000; "Deaths outside of prisons and Camps" 473,000; "Murdered in Eastern Regions" 100,000; "Deaths in other countries" 2,000. These figures include about 200,000 Polish speaking Jews who are considered Poles in Polish sources. Jews-Polish researchers have determined that the Nazis murdered 1,860,000 Polish Jews in the extermination camps in Poland, plus another 1.0 million Polish Jewish deaths in prisons and ghettos. In addition 970,000 Jews from other nations were murdered in the Nazi extermination camps in Poland. In the Polish figures of war dead are included 2.0 million Polish citizens of the Polish areas annexed by the Soviet Union, that were occupied by German Nazy forces after Operation Barbarossa, 22 June 1941. Contemporary Russian sources include these losses with Soviet war deaths. Deaths Due to Soviet Occupation The Polish Institute of National Remembrance (IPN) researchers estimated that 150,000 Polish citizens were executed due to Soviet repressions or died during deportations. Since the collapse of the USSR, Polish scholars have been able to do research in the Soviet archives on Polish losses during the Soviet occupation. Andrzej Paczkowski puts the number of Polish deaths at 90–100,000 of the 1.0 million persons deported and 30,000 executed by the Soviets. 5.

Post-Second World War (1945–present)


Early post-war period

Before World War II, a third of Poland's population was composed of ethnic minority, ethnic minorities. After the war, however, Poland's minorities were mostly gone, due to the 1945 revision of borders of Poland (1945), revision of borders, and the Holocaust. Under the National Repatriation Office (''Państwowy Urząd Repatriacyjny''), millions of Poles were expulsion of Poles after World War II, forced to leave their homes in the eastern Kresy region and settle in the western Recovered Territories, former German territories. At the same time approximately 5 million remaining Germans (about 8 million had already fled or had been expelled and about 1 million had been killed in 1944–46) were similarly expulsion of Germans after World War II, expelled from those territories into the Allied occupation zones. Ukraine, Ukrainian and

s in Poland, which formed the largest Jewish community in pre-war Europe at about 3.3 million people, was all but destroyed by 1945. Approximately 3 million Jews died of starvation in ghettos and labor camps, were slaughtered at the German Nazi extermination camps or by the Einsatzgruppen death squads. Between 40,000 and 100,000 Polish Jews survived the Holocaust in Poland, and another 50,000 to 170,000 were repatriated from the Soviet Union, and 20,000 to 40,000 from Germany and other countries. At its postwar peak, there were 180,000 to 240,000 Jews in Poland, settled mostly in Warsaw,

and Wrocław. Poland's population diminished from 35 million in 1939 to just under 24 million in 1946. According to the national census, which took place on 14 February 1946, the number of inhabitants was 23,930,000, out of which 32% lived in cities and towns, and 68% lived in the countryside. The 1950 census (3 December 1950) showed the population rise to 25,008,000, and the 1960 census (6 December 1960) placed the population of Poland at 29,776,000. In 1950, Warsaw was the biggest city of the country, with population of 804,000. Second was Lodz (pop. 620,000), third Kraków (pop. 344,000), fourth Poznan (pop. 321,000), and fifth Wroclaw (pop. 309,000). Females were in the majority in the country. In 1931, there were 105.6 women for 100 men. In 1946, the difference grew to 118.5/100, but in subsequent years, number of males grew, and in 1960, the ratio was 106.7/100.

lived in territories incorporated into the Soviet Union, USSR. Small Ukrainian, Belarusian, Slovaks, Slovak, and Lithuanians, Lithuanian minorities reside along the borders, and a German minority is concentrated near the southwestern city of Opole and in Masuria. Groups of Ukrainians and Polish Ruthenians also live in western Poland, where they were forcefully resettled by communists. As a result of the migrations and the Soviet Unions radically altered borders under the rule of Joseph Stalin, the population of Poland became one of the most ethnically homogeneous in the world. Virtually all people in Poland claim Polish nationality, with Polish language, Polish as their native tongue. Ukrainians resp. Rusyns, the largest minority group, are scattered in various northern districts. Lesser numbers of Belarusians and Lithuanians live in areas adjoining Belarus and Lithuania. The Jewish community, almost entirely Polonized, has been greatly reduced. In Silesia a significant segment of the population, of mixed Polish and German ancestry, tends to declare itself as Polish or German according to political circumstances. Minorities of Germans remain in Pomerania, Silesia, East Prussia, and Lubus. Small populations of Polish Tatars still exist. Some Polish towns, mainly in northeastern Poland have mosques. Tatars arrived as mercenary soldiers beginning in the late 14th century. The Tatar population reached approximately 100,000 in 1630 but is less than 500 in 2000.
