to the South African rand, subsuming Eswatini's monetary policy to South Africa. Customs duties from the Southern African Customs Union and worker remittances from South Africa substantially supplement domestically earned income. Eswatini is not poor enough to merit an IMF programme; however, the country is struggling to reduce the size of the civil service and control costs at public enterprises. The government is trying to improve the atmosphere for foreign direct investment. Public services are very poorly developed: the country has only twelve public ambulances, elementary schools generally no longer provide canteens and pharmacies are disappearing. An economic circle of 15,000 businessmen takes most of the country's wealth. This circle includes South African investors who have come to Eswatini to find a workforce that is three times cheaper and a group of white businessmen who are heirs to the British settlers. King Mswati III receives 8% of the national budget for official expenses. The police force receives 5% of the budget, as do the armed forces. Demographics The majority of Eswatini's population is ethnically Swazi, mixed with a small number of Zulu and White Africans, mostly people of British and Afrikaner descent. Traditionally Swazi have been subsistence farmers and herders, but most now mix such activities with work in the growing urban formal economy and in government. Some Swazi work in the mines in South Africa. Eswatini also received Portuguese settlers and African refugees from Mozambique. Christianity in Eswatini is sometimes mixed with traditional beliefs and practices. Many traditionalists believe that most Swazi ascribe a special spiritual role to the monarch. Languages SiSwati (also known as Swati, Swazi or Siswati) is a Bantu language of the Nguni Group, spoken in Eswatini and South Africa. It has 2.5 million speakers and is taught in schools. It is an official language of Eswatini, along with English, and one of the official languages of South Africa. English is the medium of communication in schools, conducting business, and the press. About 76,000 people in the country speak Zulu. Tsonga, which is spoken by many people throughout the region is spoken by about 19,000 people in Eswatini. Afrikaans is also spoken by some residents of Afrikaner descent. Portuguese has been introduced as a third language in the schools because of the large community of Portuguese speakers from Mozambique or Northern and Central Portugal. Religion Eighty-three percent of the total population adheres to Christianity in Eswatini.
