Slovakia has an estimated population of 5.4 million, compared to 5.39 million at the 2011 census. The population density is 111 people per square kilometer, which ranks 88th in the world, although the density is much higher in the capital, which has a population density of 1,131 people per square kilometer.
The capital and largest city is Bratislava, with a population of 413,000, followed by Kosice with 241,000 residents. These are the only cities with a population of more than 100,000.
The Slavs, ancestors of the Slovaks, arrived in the area in the 5th or 6th century. After WW II and the dissolution of the Austro-Hungarian Empire, Slovaks and Czechs created a mutual state, Czechoslovakia, until Slovakia became an independent state in 1993 and Czechoslovakia was dissolved peacefully.
The 2011 census found that most residents are Slovaks (80.7%), with Hungarians representing the second-largest ethnic group (8.5%). Other groups include Roma (2%), Czechs (0.6%), and Rusyns (0.6%), although unofficial estimates put the Roma population at 9%. Prior to World War II, there were 135,000 Jews in the country. Today, there are just 2,300 Jews in Slovakia.
62% of Slovaks are Roman Catholics, followed by Protestants (5.9%), Greek Catholics (3.8%), Orthodox (0.9%), and atheist (13.4%).
