Church of Saint George in Lalibela is a UNESCO World Heritage Site. According to the 2007 National Census, Christians make up 62.8% of the country's population (43.5% Ethiopian Orthodox, 19.3% other denominations), Muslims 33.9%, practitioners of traditional faiths 2.6%, and other religions 0.6%. The ratio of the Christian to Muslim population has largely remained stable when compared to previous censuses conducted decades ago. Sunnis form the majority of Muslims with non-denominational Muslims being the second largest group of Muslims, and the Shia and Ahmadiyyas are a minority. Sunnis are largely Shafi'is or Salafis, and there are also many Sufi Muslims there. The large Muslim population in the northern Afar region has resulted in a Muslim separatist movement called the "Islamic State of Afaria" seeking a sharia-compliant constitution.
