Christianity is the second largest religious grouping in Goa, India. According to the 2011 census, 25% of the resident population are Christian, while 66% are Hindu. The Christian population is almost entirely Goan Catholics, whose ancestors converted to Christianity during Portuguese rule. The Hindu population is mostly descended from migrants from other states of India, who have been arriving in Goa since the last century (Ethnic Goans represent less than 50% of the state's residents.)There is a higher proportion of Christians in Velhas Conquistas than in Novas Conquistas.
