The Catholic branch of Christianity is the dominant religion in Mexico, representing 78% of the total population as of 2020. In recent decades the share of Catholics has been declining, due to the growth of other Christian denominations – especially various Protestant churches, Jehovah's Witnesses, and Mormonism – which now constitute larger shares of the population.
The government does not provide financial contributions to the religious institutions, nor does the Roman Catholic Church participate in public education. In a major reversal of the Mexican state's restrictions on religion, the constitution was amended in 1992 lifting almost all restrictions on religions, including granting all religious groups legal status, limited property, and lifting restrictions on the number of priests in the country. Until recently, priests did not have the right to vote, and even now they cannot be elected to public office.
