In short
Weekly Mass attendance in Italy has roughly halved over two decades, falling from 36.4% to 18.8%, according to ISTAT. In 2023, 17.9% of Italians attended religious services weekly or more, while 31.5% never attended. About 10 million people still attend weekly in 2024 (10.2 million), up slightly from 2023. The decline is sharpest among the young: about 66% of 14 to 24 year olds rarely or never attend church, and among young Catholics aged 18 to 34 only 10.9% attend Mass regularly.

Italy has long been seen as one of the most Catholic countries in Europe, but weekly church attendance has fallen steeply. Over two decades, the share of Italians who attend Mass every week roughly halved, from 36.4% to 18.8%, according to ISTAT, the national statistical institute. In 2023, 17.9% of Italians attended religious services weekly or more, while 31.5% never attended at all. In absolute terms about 10 million people still go to church each week in 2024 (10.2 million), a figure that ticked up slightly from 2023. The steepest drop is generational: about two thirds of 14 to 24 year olds rarely or never attend, and among young Catholics only about one in ten goes to Mass regularly. The figures below draw on ISTAT, the most authoritative source on religious practice in Italy.

Weekly attendance has roughly halved
The clearest long-run trend in Italy is the erosion of weekly Mass attendance. Two decades ago more than a third of Italians attended a religious service every week. Today that share is below one in five, a decline of nearly half, according to ISTAT.

The generational cliff
The decline is far from even across age groups. Older Italians remain the backbone of weekly congregations, while young people have largely stepped away from regular practice. Among the youngest cohorts, rare or no attendance is now the norm.
About 66% of 14 to 24 year olds rarely or never attend church, according to ISTAT.
Among young Catholics aged 18 to 34, only 10.9% attend Mass regularly, according to ISTAT.
| Statistic | Value | Year | Source |
|---|---|---|---|
| 14 to 24 year olds who rarely or never attend | about 66% | 2023 | ISTAT |
| Young Catholics (18 to 34) attending regularly | 10.9% | 2023 | ISTAT |
| Italians who never attend (all ages) | 31.5% | 2023 | ISTAT |
Identity versus practice
Formal Catholic identity in Italy remains far more widespread than regular practice. Even as weekly attendance falls, roughly 10 million people still fill churches each week, and that absolute figure ticked up slightly in 2024. The gap between people who identify as Catholic and those who attend regularly is wide.
About 10 million people attend weekly in 2024 (10.2 million), up slightly from 2023, according to ISTAT.
In 2023, 31.5% of Italians never attended religious services, according to ISTAT.

How we compiled these statistics
Every number on this page is traceable to ISTAT, the Italian national statistical institute, and dated to the year the data were collected. Attendance figures come from ISTAT surveys on the aspects of daily life, which ask how often people attend religious services. Where a share is compared over time, we report both the earlier and the recent reading and label each year. The absolute count of weekly attenders for 2024 is derived from the same ISTAT source. Where the survey reports age breakdowns, we quote them as ISTAT publishes them.
