the country. Zambia has a small but economically important Asian population, most of whom are Indians and Chinese. This minority group has a massive impact on the economy controlling the manufacturing sector. An estimated 80,000 Chinese reside in Zambia. In recent years, several hundred dispossessed white farmers have left Zimbabwe at the invitation of the Zambian government, to take up farming in the Southern province. Zambia has a minority of coloureds of mixed race. During colonialism, segregation separated coloureds, blacks and whites in public places including schools, hospitals, and in housing. There has been an increase in interracial relationships due to Zambia's growing economy importing labor. Coloureds are not recorded on the census but are considered a minority in Zambia. According to the World Refugee Survey 2009 published by the U.S. Committee for Refugees and Immigrants, Zambia had a population of refugees and asylum seekers numbering approximately 88,900. The majority of refugees in the country came from the Democratic Republic of the Congo (47,300 refugees from the DRC living in Zambia in 2007), Angola (27,100; see Angolans in Zambia), Zimbabwe (5,400) and Rwanda (4,900). Zambians are generally welcoming towards foreigners. Beginning in May 2008, the number of Zimbabweans in Zambia began to increase significantly; the influx consisted largely of Zimbabweans formerly living in South Africa who were fleeing xenophobic violence there. Nearly 60,000 refugees live in camps in Zambia, while 50,000 are mixed in with the local populations. Refugees who wish to work in Zambia must apply for permits, which can cost up to $500 per year. Religion Zambia is officially a "Christian nation" under the 1996 constitution, but recognizes and protects freedom of religion. While fewer than three percent of the population still observe indigenous faiths, Zambian Christianity is highly syncretic, and many self-identified Christians blend elements of traditional African religion with their faith. About three-fourths of the population adheres to one of several Protestant denominations, including Anglicanism, New Apostolic Church, Lutheranism, Jehovah's Witnesses, the Seventh-day Adventist Church, and the Church of Jesus Christ of Latter-day Saints; many Zambians also observe broader, nondenominational Christian movements, such as Branhamism, Pentecostalism, and Evangelical denominations. Roughly one-fifth are Roman Catholic. Christianity arrived to Zambia through missionary work in the second half of the 19th century, and its wide variety of sects and movements reflect changing patterns of missionary activity; for example, Catholicism came from Portuguese Mozambique in the east, while Anglicanism reflects
