Quote from the article: “The Soviets … deported between 1.5 million and 2 million Poles to Siberia.”
The real number of the deportees is 320.000 people of all ages and genders.
The number is obtained by Ośrodka KARTA - a Polish independent non-governmental organization (incorporated as a foundation), documenting and popularizing the recent history of Poland and Eastern Europe. It continues the activities of the illegal “Karta” and the clandestine Eastern Archives of the 1980s.
Of those 320.000 deported roughly 20.000 died (top estimate) during the time in USSR, i.e. during the periods from 11 to 16 months (There were 3 ways of deportation, thefore 3 groups of deportees spent different time spans.). This constitutes average yearly death rate of 6,3%. For comparisson the yearly mortality rate in USSR in 1940 was 1,7%.
