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.
Migrations from Poland since EU accession
According to a 2013 survey, approximately 14% percent of adult Poles have worked abroad since 2004 (approximately a quarter for over a year); 69% have a family member of a close friend who lives abroad, and approximately 24% are open to immigration. Majority of Polish migrants or those considering leaving are young; according to a 2014 survey approximately 90% of Poles under 34 have considered some form of migration. Over the past decade or so, there has been a visible trend that migrants are increasingly likely to be young and well-educated.
Professor Krystyna Iglicka has estimated that up to half a million Poles emigrated in 2013. 
As of 2011, approximately 80% of Polish emigrants settle in the countries of the European Union. As of 2013, the largest group of modern Polonia can be found in the United Kingdom (550,000), followed by that in Germany (425,608)., in France (350,000 as of 2012), Significant Polish presence can also be found in Ireland (115, 000 as of 2013), in Italy (94,000 as of 2011), in the Netherlands (103,000 as of 2013), and.
