The Constitution guarantees freedom of religion but also requires the government to support Roman Catholicism economically. Catholic policy remains influential in government though, and still helps shape a variety of legislation. In a study assessing world-wide levels of religious regulation and persecution, with scores ranging from 0–10 where 0 represented low levels of regulation or persecution, Argentina received a score of 1.4 on Government Regulation of Religion, 6.0 on Social Regulation of Religion, 6.9 on Government Favoritism of Religion and 6 on Religious Persecution.
According to the World Christian Database Argentines are: 92.1% Christian, 3.1% agnostic, 1.9% Muslim, 1.3% Jewish, 0.9% atheist, and 0.9% Buddhist and others. Argentine Christians are mostly Roman Catholic with estimates for the number of Catholics varying from 70% to 90% of the population (though perhaps only 20% attend services regularly).
Argentina has the largest Jewish population of any country in Latin America. A recent study found that approximately 11% of Argentines are non-religious (which includes those who believe in God but do not follow a religion), 4% are agnostics and 5% are atheist. Overall 24% attended religious services regularly. Protestants were the only group with a majority of followers who regularly attended services
