Its capital, Luxembourg City, is one of the four official capitals of the European Union and the seat of the Court of Justice of the European Union, the highest judicial authority in the EU. Its culture, people, and languages are highly intertwined with its neighbors, making it a mixture of French and German cultures. It has three official languages: French, German, and the national language of Luxembourgish.
With an area of 2,586 square kilometers, it is one of the smallest sovereign states in Europe. In 2019, Luxembourg had a population of 626,108, which makes it one of the least-populous countries in Europe, but by far the one with the highest population growth rate. Foreigners account for nearly half of Luxembourg's population. As a representative democracy with a constitutional monarch, it is headed by Grand Duke Henri and is the world's only remaining sovereign grand duchy. Luxembourg is a developed country, with an advanced economy and one of the world's highest GDP per capita.
