Roman Catholicism has long been the main religion of Spain, and although it no longer has official status by law, in all public schools in Spain students have to choose either religion or ethics and Catholic is the only religion officially taught although in some schools there are large numbers of Muslim students together. According to a July 2009 study by the Spanish Center of Sociological Research about 73% of Spaniards self-identify as Catholics, 2.1% other faith, and about 22% identify with no religion among which 7.3% are atheists. Most Spaniards do not participate regularly in religious services. This same study shows that of the Spaniards who identify themselves as religious, 58% hardly ever or never go to church, 17% go to church some times a year, 9% some time per month and 15% every Sunday or multiple times per week.

Religious freedom was granted in the Constitution of 1978
