American adults – both Christian and unaffiliated – are considerably more religious than their European counterparts by a variety of measures. For instance, about two-thirds of U.S. Christians pray daily, compared with a median of just 18% of Christians across 15 European countries.
Across Western Europe, people who say they personally know a Muslim are generally more likely than others to have positive opinions of Muslims and their religion. However, knowing something about Islam – as opposed to personally knowing a Muslim – is less associated with positive feelings of Muslims and Islam.
