In 2023, the population of Luxembourg amounted to over 660,000. The largest age groups were formed by those between 35 and 39 years old (53,800 people) and between 40 and 44 years old (51,900 people). By comparison: only 4,900 people were 90 years or older.

 Luxembourg’s foreign population  

Just like Andorra or Monaco, Luxembourg has a large foreign population. Almost as many people with a foreign citizenship as Luxembourgish citizens live in the country. In 2022, the share of foreign nationals living in the Grand Duchy reached just over 47 percent. That year, of Luxembourg’s population roughly 341 thousand people had the Luxembourgish nationality, the remaining 304 thousand were foreign nationals.  

Differences between the Luxembourgish and foreign nationals  

Comparing the Luxembourgish and the foreign nationals, most of the foreign nationals were between 35 and 39 years old. Among the Luxembourgish nationals, this was also a large group, but the largest age groups were composed of those 20 to 24 years old.

In 1800, the population of Luxembourg was estimated to be 127,000, a figure which would rise steadily through the early 19 th century as the country would become an increasingly prominent city in the region. Luxembourg’s population would see its first major period of growth following the defeat of Napoleon in 1815, which would result in the previously-French occupied Luxembourg being granted formal autonomy in the subsequent Congress of Vienna. As a largely agrarian state at this time, the population of Luxembourg would see several periods of growth and decline throughout the remainder of the 20th century, as many residents emigrated abroad to countries such as the United States in search of work. Nevertheless, the population of Luxembourg would rise to over 235,000 by the turn of the century, as Dutch modernization and the removal of the city’s fortifications in the 1867 Treaty of London would allow for a greater expansion of the city proper.

The first half of the 20 th century would largely be a period of stagnation for the country, as the country would see large periods of stagnation in the 1910s and throughout the 1930s and 1940s, as occupation in both World Wars and the 1918 Spanish Flu epidemic) would see massive damage to the city in both human and economic terms. Luxembourg’s population would see significant growth in the country’s population, particularly so following the creation of the European Union in 1958 (Luxembourg was one of the six founding members of the union). Growth would accelerate even further following the 1980s, as increases in industrialization and accompanying economic growth would lead to an increasingly growing immigrant population from other EU nations in Luxembourg, which by 2015 would account for nearly half the citizens in Luxembourg. As a result of this growth, in 2020, Luxembourg is estimated to have a population of 626,000.

Based on the asking price from one of Luxembourg's real estate agencies, there were large differences in residential property prices in the different neighborhoods of Luxembourg City. The average price (which includes both houses as well as apartments) was highest in the city district of Limpertsberg: more than 12,000 euros per square meter. The district of Weimerskirch was nearly twice as cheap with an average price of 6,800 euros per square meter. Nearly one third of the population in the Grand Duchy of Luxembourg lived in the canton of Luxembourg (Luxembourg City and its surroundings in 2019).

The cities in Europe where survey respondents most commonly indicated that they were a good place to live for gay and lesbian people were Rekjavik,Valletta and Groningen in 2023. In general, the cities which ranked as the best place to live for lesbian and gay people in Europe were in Nordic countries (Norway, Iceland, Copenhagen, Sweden, Finland), western European countries (Luxembourg, Germany, the Netherlands), and southern European countries (Italy, Malta, Spain). The five cities with the fewest respondents indicating that they were a good place to live were all in south-eastern Europe, with the bottom two both coming from Turkey (Diyarbakir) and Albania (Tirania). Turkey tends to rank so lowly due to the influence of traditionalist and religious social norms, which do not recognize LGBTQ relationships as being on a par as heterosexual relationships and lead to more commonly held homophobic views.
