Which country has the world’s largest Muslim population celebrating Ramadan and Eid?

The story behind the answer

Indonesia has the world’s largest Muslim population celebrating Ramadan and Eid.

Indonesia is a Muslim-majority country in Southeast Asia, and its Muslim population is larger than that of any other country. Ramadan and Eid al-Fitr are major national and social occasions there, combining worship with family gatherings, charitable giving, special foods, and travel.

Indonesian Muslims commonly call Eid al-Fitr Lebaran. The annual homecoming journey associated with the holiday is known as mudik, when millions of people travel from cities to ancestral hometowns. This tradition is separate from the religious meaning of Eid but is one of the festival’s most visible national features.

Indonesia’s Muslim population is predominantly Sunni, although the country is religiously diverse and officially recognizes several religions. Population rankings can change with census methods, but Indonesia’s position as the country with the largest Muslim population is a long-established demographic fact.
