German and Soviet occupation. Fundamental issues. : "Straty ludnosci panstwa polskiego narodowosci ukrainskiej sa trudne do wyliczenia," Translation: "The losses of ethnic Poles of Ukrainian nationality are difficult to calculate." Note: Polish losses amount to 11.3% of the 24.4 million ethnic Poles in prewar Poland and about 90 percent of the 3.3 million Jews of prewar times. The IPN figures do not include losses among Polish citizens of Ukrainian và Belarusian ethnicity.
