10. Mexico
Attendance: 50.1%
According to Pew, Mexico is home to the second largest Catholic population in the globe, where 81% of the people practice Catholicism. While a strong majority of the country practices, only about half that amount actually attend mass on a regular basis. Even more interestingly, Mexico’s Catholics tend to have opposing views on major topics like same-sex marriage and contraception, which are big topics of discussion for the church.
