In short
Church attendance in Belgium has fallen dramatically over two generations. In 2022, only 8.9% of Belgians said they regularly attend Mass, down from about 50% in the 1960s, according to the Belgian Bishops Conference. The counted headcount tells the same story: attendance on the annual count Sunday fell from 286,400 in 2016 to 167,400 in 2023. Weekly Mass attendance did tick up to 173,335 in 2024 from 167,360 in 2023. Half of Belgians (50%) still identified as Catholic in 2023, showing that Catholic identity outlasts regular practice.

Belgium was long one of the most Catholic countries in Europe, but regular churchgoing has collapsed over two generations. In 2022, only 8.9% of Belgians said they regularly attend Mass, down from about 50% in the 1960s, according to the Belgian Bishops Conference. The counted headcount on the annual census confirms the decline: attendance on the count Sunday fell from 286,400 in 2016 to 167,400 in 2023. There are small signs of stabilisation, with weekly Mass attendance rising to 173,335 in 2024 from 167,360 in 2023. At the same time, Catholic identity outlasts practice: half of Belgians still identified as Catholic in 2023. The figures below draw on the Belgian Bishops Conference and Vatican News, the most authoritative sources on church attendance in Belgium.

How few Belgians practise today
Regular Mass attendance in Belgium has fallen from about half the population in the 1960s to under one in ten today. That decline is one of the steepest in Western Europe, and it reshapes how the Catholic Church operates across the country.

A long collapse since 2016
The annual church census, taken on a single count Sunday, offers a counted headcount rather than a survey. It shows how quickly the numbers have thinned in just a few years, though the most recent weekly figure points to a small recovery.

Catholic identity outlasts practice
Formal identity in Belgium runs far ahead of lived practice. Half the population still calls itself Catholic even though fewer than one in ten attend Mass regularly, a gap common across secularising Europe. But even that identity share is slipping.
In 2023, 50% of Belgians identified as Catholic, down from nearly 53% in 2018, according to the Belgian Bishops Conference.

How we compiled these statistics
Every number on this page is traceable to a primary source and dated to the year the data were collected. The count Sunday and weekly Mass attendance figures are counted headcounts from the annual church census reported by the Belgian Bishops Conference, not survey estimates. The regular-attendance and Catholic-identity shares come from the same church reporting, with additional coverage from Vatican News. Where data years differ, we use the most recent published year and label it.
