LONDON (RNS) — New research indicates that within the next 12 years, the number of Muslims worshipping at mosques in Britain will outstrip that of Roman Catholics attending traditional church services.

According to a report by London’s Daily Telegraph newspaper on March 25, the study by Britain’s Christian Research organization estimates that, based on present trends, the number of Catholics attending Sunday Mass will have dropped to 679,000 by 2020.

At the same time, the report’s statisticians say, the number of Muslims in attendance at mosques will have climbed to 683,000.

The Telegraph says the Christian Research report, based on British government and academic information as well as the firm’s own Religious Trends study, comes “amid growing tensions over the place of Muslims in British society.”

Such tensions include claims by Christian clerics that “no-go” areas for non-Muslims are springing up in parts of the country.
