The survey found Northern Ireland was the most observant UK region
Christian charity Tearfund's survey found 45% of people in Northern Ireland attended church services every month.
It found 30% went weekly, while 54% went at least once a year. Of those surveyed, 41% said they never went.
Chief executive Matthew Frost said the UK-wide survey of 7,000 people made it clear "that the UK is holding firmly to the Christian faith".
In the report, Churchgoing in the UK, it says: "Northern Ireland is very different from the rest of the UK in that 81% are Christians and only 0.4% belong to other religions."
It says Northern Ireland has "only 44% either de-churched or non-churched".
Scotland has 18% regular attendance, which is slightly above average, followed by England at 14% and Wales at 12%.
The European Social Survey in 2002 found the Irish Republic had 67.2% attendance at religious services.
Poland had the highest attendance, with 75.5% worshipping regularly.
