Demographics

Austria's population estimate in October 2006 was 8,292,322. The population of the capital, Vienna, exceeds 1.6 million (2.2 million with suburbs) , representing about a quarter of the country's population and is known for its vast cultural offerings and high standard of living.
In contrast to the capital, other cities do not exceed 1 million inhabitants: the second largest city Graz is home to 250,099 inhabitants, followed by Linz (188,968), Salzburg (150,000), and Innsbruck (117,346). All other cities have fewer than 100,000 inhabitants.
German-speaking Austrians, by far the country's largest group, form roughly 90% of Austria's population. The Austrian federal states of Carinthia and Styria are home to a significant indigenous Slovenian minority with around 14,000 members (Austrian census; unofficial numbers of Slovene groups speak of up to 50,000). About 20,000 Hungarians and 30,000 Croatians live in the east-most Bundesland, Burgenland (formerly part of the Hungarian half of Austria-Hungary). The remaining number of Austria's people are of non-Austrian descent, many from surrounding countries, especially from the former East Bloc nations. So-called guest workers (Gastarbeiter) and their descendants, as well as refugees from Yugoslav wars and other conflicts, also form an important minority group in Austria. Since 1994 the Roma-Sinti (gypsies) are an officially recognized ethnic minority in Austria.
According to census information published by Statistik Austria for the year 2001 there were a total of 710,926 foreign nationals living in Austria. Of these, 124,392 speak German as their mother tongue (presumably immigrants from Germany, Switzerland, Liechtenstein, the Windische Slovenians and also the South Tyrolian part of northern Italy.) The next largest populations of linguistic and ethnic groups are 240,863 foreign nationals from the former Yugoslavia (Serbian being the largest number of these at 135,376, followed by Croatian at 105,487); 123,417 Turkish nationals; 25,155 whose native tongue is English; 24,446 Albanian; 17,899 Polish; 14,699 Hungarian; 12,216 Romanian; 7,982 Arabs; 6,902 Slovenian (not including the Windisch minority); 6,891 Slovakian; 6,707 Czech; 5,916 Persian; 5,677 Italian; 5,466 Russian; 5,213 French; 4,938 Chinese; 4,264 Spanish; 3,503 Bulgarian. The populations of the rest fall off sharply below 3,000.
The mother tongue of the population by prevalence, is German (88.6%) followed by Turkish (2.3%) , Serbian (2.2%) , Croatian (1.6%) , Hungarian (0.5%) and Bosnian (0.4%).
The official language, German, is spoken by almost all residents of the country. Austria's mountainous terrain led to the development of many distinct German dialects. All of the dialects in the country, however, belong to Austro-Bavarian groups of German dialects, with the exception of the dialect spoken in its western-most Bundesland, Vorarlberg, which belongs to the group of Alemannic dialects. There is also a distinct grammatical standard for Austrian German with a few differences to the German spoken in Germany.
As of 2006, some of the Austrian states introduced standardised tests for new citizens, to assure their language ability, cultural knowledge and accordingly their ability to integrate into the Austrian society.

Politics concerning ethnic groups (Volksgruppenpolitik)
An estimated 13,000 to 40,000 Slovenians in the Austrian state of Carinthia (the Carinthian Slovenes) as well as Croatians (around 30,000) and Hungarians in Burgenland were recognized as a minority and have enjoyed special rights following the Austrian State Treaty (Staatsvertrag) of 1955. The Slovenians in the Austrian state of Styria (estimated at a number between 1,600 and 5,000) are not recognized as a minority and do not enjoy special rights, although the State Treaty of July 27, 1955 states otherwise.
The right for bilingual topographic signs for the regions where Slovene- and Croat-Austrians live alongside the Germanic population (as required by the 1955 State Treaty) is still to be fully implemented. Many Carinthians are afraid of Slovenian territorial claims, pointing to the fact that Yugoslav troops entered the state after each of the two World Wars and considering that some official Slovenian atlases show parts of Carinthia as Slovenian cultural territory. The current governor, Jörg Haider, has made this fact a matter of public argument in autumn 2005 by refusing to increase the number of bilingual topographic signs in Carinthia. A poll by the Kärntner Humaninstitut conducted in January 2006 states that 65% of Carinthians are not in favour of an increase of bilingual topographic signs, since the original requirements set by the State Treaty of 1955 have already been fulfilled according to their point of view. Another interesting phenomenon is the so called "Windischen-Theorie" stating that the Slovenians can be split in two groups: actual Slovenians and Windische (a traditional German name for Slavs) , based on differences in language between Austrian Slovenians, who were taught Slovenian standard language in school and those Slovenians who spoke their local Slovenian dialect but went to German schools. The term Windische was applied to the latter group as a means of distinction. This theory was never generally accepted and fell out of use some decades ago.
