Muslims constitute the second largest religious group in Thailand, comprising 5.4% of the population in 2018. Islam is concentrated mostly in the country's southernmost provinces: Pattani, Yala, Satun, Narathiwat, and part of Songkhla Chumphon, which are predominantly Malay, most of whom are Sunni Muslims. Christians represented 1.13% (2018) of the population in 2018, with the remaining population consisting of Hindus and Sikhs, who live mostly in the country's cities. There is also a small but historically significant Jewish community in Thailand dating back to the 17th century.
