Religion

The Constitution of Belgium provides for freedom of religion, and the government respects this right in practice. Belgium officially recognizes three religions: Christianity (Catholic, Protestantism, Orthodox churches and Anglicanism), Islam and Judaism. During the reigns of Albert I and Baudouin, the Belgian royal family had a reputation of deeply rooted Catholicism.

Catholicism has traditionally been Belgium's majority religion; being especially strong in Flanders. However, by 2009 Sunday church attendance was 5% for Belgium in total; 3% in Brussels, and 5.4% in Flanders. Church attendance in 2009 in Belgium was roughly half of the Sunday church attendance in 1998 (11% for the total of Belgium in 1998). Despite the drop in church attendance, Catholic identity nevertheless remains an important part of Belgium's culture.

According to the Eurobarometer 2010, 37% of Belgian citizens believe in God, 31% in some sort of spirit or life-force. 27% do not believe in any sort of spirit, God, or life-force. 5% did not respond. According to the Eurobarometer 2015, 60.7% of the total population of Belgium adhered to Christianity, with Catholicism being the largest denomination with 52.9%. Protestants comprised 2.1% and Orthodox Christians were the 1.6% of the total. Non-religious people comprised 32.0% of the population and were divided between atheists (14.9%) and agnostics (17.1%). A further 5.2% of the population was Muslim and 2.1% were believers in other religions. The same survey held in 2012 found that Christianity was the largest religion in Belgium, accounting for 65% of Belgians.

In the early 2000s, there were approximately 42,000 Jews in Belgium. The Jewish Community of Antwerp (numbering some 18,000) is one of the largest in Europe, and one of the last places in the world where Yiddish is the primary language of a large Jewish community (mirroring certain Orthodox and Hasidic communities in New York, New Jersey, and Israel). In addition, most Jewish children in Antwerp receive a Jewish education. There are several Jewish newspapers and more than 45 active synagogues (30 of which are in Antwerp) in the country.A 2006 inquiry in Flanders, considered to be a more religious region than Wallonia, showed that 55% considered themselves religious and that 36% believed that God created the universe. On the other hand, Wallonia has become one of Europe's most secular/least religious regions. Most of the French-speaking region's population does not consider religion an important part of their lives, and as much as 45% of the population identifies as irreligious. This is particularly the case in eastern Wallonia and areas along the French border.

A 2008 estimate found that approximately 6% of the Belgian population (628,751 people) is Muslim. Muslims constitute 23.6% of the population of Brussels, 4.9% of Wallonia and 5.1% of Flanders. The majority of Belgian Muslims live in the major cities, such as Antwerp, Brussels and Charleroi. The largest group of immigrants in Belgium are Moroccans, with 400,000 people. The Turks are the third largest group, and the second largest Muslim ethnic group, numbering 220,000.
