The Catholic Church in India is part of the worldwide Catholic Church under the leadership of the Pope. There are over 20 million Catholics in India, representing around 1.55% of the total population, and the Catholic Church is the single largest Christian church in India. There are 10,701 parishes that make up 174 dioceses and eparchies, which are organised into 29 ecclesiastical provinces. Of these, 132 dioceses are of the Latin Church, 31 of the Syro-Malabar Catholic Church and 11 of the Syro-Malankara Catholic Church. Despite the very small population that Indian Catholics make up percentage wise, India still has the second-largest Christian population in Asia after the Catholic Church in the Philippines.
