Poles
Polish people are the sixth largest national group in the European Union. Estimates vary depending on source, though available data suggest a total number of around 60 million people worldwide (with roughly 21 million living outside of Poland, many of whom are not of Polish ethnicity, but Polish nationals). There are almost 38 million Poles in Poland alone. There are also Polish minorities in the surrounding countries including (Germany), and indigenous minorities in the Czech Republic, Hungary, Slovakia, northern and eastern Lithuania, western Ukraine, and western Belarus. There are some smaller indigenous minorities in nearby countries such as Moldova. There is also a Polish minority in Russia which includes indigenous Poles as well as those forcibly deported during and after World War II; the total number of Poles in what was the former Soviet Union is estimated at up to 3 million.
Vietnamese people in Poland
There are no precise data on the number of Vietnamese people in Poland, as many, likely at least 50%, are illegal immigrants. The Polish census of 2011 had 4,027 respondents indicate Vietnamese as their nationality. The Vietnamese embassy and Vietnamese community leaders in Poland estimate that about 20,000 to 30,000 Vietnamese people may reside in Poland, though the Polish government in 2002 put the upper possible range at about 50,000. A 2008 Polish government report gave the range of 25,000–60,000, a 2012 media report also suggested an upper range of 60,000, while a 2014 academic paper provided an estimate of 35,000, with a note that this number is "hard to estimate". As they are Poland's largest immigrant community whose culture is not European, they are also one of Poland's most visible immigrant groups. Members of the Polish public commonly hold the mistaken belief that Vietnamese form Poland's largest foreign community, a title which in fact belongs to migrants from the former USSR.
