context_page_description: 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 fourth-largest Christian population in Asia after the Philippines, China and India. Indonesia's 28.6 million Christians constitute 10.72% of the country's population in 2018, with 7.60% Protestant and 3.12% Catholic. Some provinces in Indonesia are majority Christian.
context_section_description: Among Indonesian provinces in 2010, North Sumatra reported the second-highest number of Christians (4.03 million) or 17.2% of Christians within Indonesia. North Sumatra had the seventh-highest percentage (among religions reported in the province) of Christians (31.01%), including the sixth-highest percentage of Protestants (27.03%), and 3.97% Catholic population. However, this varies by regency—the Nias islands are 95%+ Christian of Nias ethnicity, and all of the areas surrounding Lake Toba have large Christian populations of the Batak Toba, Karo and Pakpak ethnic groups. Apart from this, most other parts of North Sumatra have a significant Christianity percentage (around 20 to 40%), with the exception of Langkat, in the northeast coast, Asahan on the east coast, and the Mandailing regencies in the south which are Muslim majority (below 10%).
