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.
Geography of Poland
Poland is a country in East-Central Europe with an area of 312,679 square kilometres (120,726 sq. mi.), and mostly temperate climate. Generally speaking, Poland is an almost unbroken plain reaching from the Baltic Sea in the north, to the Carpathian Mountains in the south. Within that plain, terrain variations run in bands east to west. 
The Baltic coast has two natural harbors, the larger one in the Gdańsk-Gdynia region, and a smaller one near Szczecin in the far northwest. The northeastern region, also known as the Masurian Lake District with more than 2,000 lakes, is densely wooded and sparsely populated. To the south of the lake district, and across central Poland a vast region of plains extends all the way to the Sudetes on the Czech and Slovak borders southwest, and to the Carpathians on the Czech, Slovak and Ukrainian borders southeast. The central lowlands had been formed by glacial erosion in the Pleistocene ice age. The neighboring countries are Germany to the west, the Czech Republic and Slovakia to the south, Ukraine and Belarus to the east, and Lithuania and the Russian exclave of Kaliningrad to the northeast.
