The International Religion Monitor finds that Christianity is still strong in Europe, but that religiosity differs greatly between countries:
According to a representative study by the Bertelsmann Stiftung’s Religion Monitor, the Christian faith still has a strong influence in Europe. Three-fourth of all Europeans (74 percent) in the countries surveyed are religious and one-fourth (25 percent) are highly religious. Only 23 percent of Europeans are non-religious. Thanks to this interdisciplinary measuring instrument, it was possible to ascertain both religious variety as well as the intensity of religious attitudes and practices. Striking differences were registered between the individual European countries, influenced heavily by national traditions. The Religion Monitor supplies directly comparable data for the seven European countries of Germany, France, Great Britain, Italy, Austria, Poland and Switzerland. In this comparison, faith and religion are most strongly rooted in Italy (89 percent) and Poland (87 percent) and most weakly rooted in secular France (54 percent).
