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.
Kresy
In January, February and March 2012, Centre for Public Opinion Research made a survey, asking Poles about their ties to the Kresy. It turned out that almost 15% of the population of Poland (4,3 - 4,6 million people) declared that they either were born in the Kresy, or have a parent or a grandparent who comes from that region. The number of "Kresowiacy" is high in northern and western Poland – as many as 51% of inhabitants of Lubusz Voivodeship, and 47% of inhabitants of Lower Silesian Voivodeship stated that their family has ties to the Kresy. Furthermore, "Kresowiacy" now make 30% of the population of Opole Voivodeship, 25% of the population of West Pomeranian Voivodeship, and 18% of the population of Warmian-Masurian Voivodeship.
