Christianity is Indonesia's second-largest religion, after Islam. Indonesia also has the second-largest Christian population in Southeast Asia after the Philippines, the largest Protestant population in Southeast Asia, and the third-largest Christian population in Asia after the Philippines and China, followed by India. Indonesia also has the second-largest Christian population in the Muslim world, after Nigeria, followed by Egypt. Indonesia's 29.1 million Christians constituted 10.49% of the country's population in 2022, with 7.43% Protestant (20.6 million) and 3.06% Catholic (8.5 million). Some provinces in Indonesia are majority Christian. In Indonesia, the word Kristen (lit. 'Christian') refers to Protestantism, while Catholicism is referred to as Katolik. In the 21st century the rate of growth and spread of Christianity has increased, especially among the Chinese minority.[3][4][5]
