Liechtenstein is the fourth smallest country of Europe, after Vatican City, Monaco, and San Marino.
Its population is primarily Alemannic-speaking, although its resident population is approximately one third foreign-born, primarily German speakers from Germany, Austria, and Switzerland, other Swiss, Italians, and Turks. Foreign-born people make up two-thirds of the country\'s workforce.
The official language is German; most speak Alemannic, a dialect of German that is highly divergent from Standard German but closely related to those dialects spoken in neighbouring regions such as Vorarlberg, Austria.
In Triesenberg, a dialect promoted by the municipality is spoken. According to the 2000 census, 87.9% of the population is Christian, of whom 78.4% adhere to the Roman Catholic faith, while about 8% are Protestant.
Compared to the 1990 census, the percentage of Christians fell, whereas Muslims and the undeclared more than doubled in size. According to a 2009 Pew Research Center report, Muslims constitute approximately 4.8% of the population.
Liechtensteiners have an average life expectancy at birth of 80.31 years, male: 76.86 years, female: 83.77 years (2011 est.). The infant mortality rate is 4.64 deaths per 1,000 live births, according to recent estimates. The literacy rate of Liechtenstein is 100%.
The Programme for International Student Assessment, coordinated by the OECD, currently ranks Liechtenstein\'s education as the 10th best in the world.
