South Sudan has a population of approximately million and a predominantly rural, subsistence economy. This region has been negatively affected by war for all but 10 of the years since 1956, resulting in serious neglect, lack of infrastructure development, and major destruction and displacement. More than 2 million people have died, and more than 4 million are
internally displaced persons or became
refugees as a result of the civil war and its impact. -funded Southern Sudan Interactive Radio Instruction project, July 2010
Population 2008 census The "Fifth Population and Housing Census of Sudan", for Sudan as a whole, was conducted in April 2008. The census counted the Southern Sudan population at 8.26 million; however, Southern Sudanese officials rejected the census results of Southern Sudan because "the central bureau of statistics in
Khartoum refused to share the national Sudan raw census data with the southern Sudan centre for census, statistics and evaluation". In addition, President Kiir "suspected figures were being deflated in some regions and inflated in others, and that made the final tally 'unacceptable'." He claimed that the Southern Sudanese population actually constituted one-third of that of Sudan, though the census showed it to be only 22%.
2009 census In 2009, Sudan initiated a Southern Sudanese census ahead of the
2011 independence referendum, which would also include the
South Sudanese diaspora; however, this initiative was criticised for leaving out countries with a high share of the South Sudanese diaspora, rather counting countries where the diaspora share was low.
Ethnic groups The major
ethnic groups present in South Sudan are the
Dinka at approximately 40 per cent of the population, the
Nuer at approximately 20 per cent, and the
Azande at approximately 10 per cent, as well as the
Shilluk and
Bari. Currently, around 800,000 expatriates from the
Horn of Africa are living in South Sudan.
Diaspora The South Sudanese diaspora consists of citizens of South Sudan residing abroad. The number of South Sudanese outside South Sudan has sharply increased since the beginning of the struggle for independence from
Sudan. Almost one and a half million South Sudanese have left the country as refugees, either permanently or as temporary workforce, leading to the establishment of the South Sudanese diaspora population. The largest communities of the South Sudanese diaspora are located in North America, Western Europe and Oceania. They can be found in the United States, Canada, United Kingdom and Australia. Small communities exist in France, Italy, Germany, Sweden, and New Zealand. Activist Achol Jok Mach has spoken out about growing up and growing up in a diaspora community and the effect on her identity, saying: "I was only ever told, 'You are South Sudanese'... It was only much later that I learned I was
Dinka."
Largest cities Languages Seventy languages are spoken in South Sudan, of which 60 are
indigenous and granted constitutional status as "
national languages" that "shall be respected, developed and promoted". English is the sole
official language, English had been the principal language of what is now South Sudan since 1972, serving as the common medium for administrative purposes. However, few South Sudanese speak it as a first language. The majority of languages spoken in South Sudan are classified within the
Nilo-Saharan Language family, specifically the subbranches of
Nile Sudanic and
Central Sudanic; most of the remainder are part of the
Adamawa-Ubangi branch of the
Niger-Congo family. The most common languages are
Dinka (1.35 million),
Nuer (740,000),
Bari (595,000), and
Zande (420,000), which are collectively spoken by approximately 60% of the population; The most common variety is
Juba Arabic, also known as South Sudanese Arabic, a
creole language that serves as the
lingua franca for local governments, national commerce, and in urban areas. It is spoken by approximately 1.45 million people, of whom only 250,000 speak it natively.
Sudanese Arabic, the prevailing dialect in Sudan, has approximately 460,000 speakers, primarily in the northern regions of South Sudan; it has been described as the
de facto language of national identity. but has no legal status in the current transitional constitution adopted in 2011.
Swahili, a
Bantu language spoken primarily in East Africa, has been proposed as a second official language. In 2011, South Sudan's ambassador to
Kenya stated that
Swahili would be introduced in South Sudan with the goal of supplanting Arabic as a
lingua franca, in keeping with the country's orientation toward the
East African Community rather than Sudan and the
Arab League. Following the South Sudan's ascension to the
East African Community in 2019, the government has moved to adopt Swahili into the official curricula at primary school. Nevertheless, South Sudan submitted an application to join the Arab League as a
member state on 25 March 2014, which is still pending. In an interview with the newspaper
Asharq Al-Awsat, the Foreign Minister of South Sudan
Deng Alor Kuol said: South Sudan is the closest African country to the
Arab world, and we speak a special kind of Arabic known as Juba Arabic. Sudan supports South Sudan's request to join the Arab League. Juba Arabic is a
lingua franca in South Sudan.
Religion in
Lakes State|279x279px South Sudan is predominantly Christian. Other religions include various traditional
indigenous belief systems, and
Islam. Exact figures are lacking due to internal displacement from ongoing conflict, large numbers of frequently-migrating pastoralists, and insufficient government resources. In 2012, the
Pew Research Center estimated its population to be 60.5% Christian, 32.9% following folk religions, and 6.2% Muslim. It maintained the same estimate in 2020. The US State Department reported in 2023 that the South Sudan Council of Churches and the government Bureau of Religious Affairs give the principal Christian denominations as Roman Catholic, Episcopal, Presbyterian, Pentecostal, Sudan Interior, Presbyterian Evangelical, and African Inland Churches. Smaller congregations of Eritrean Orthodox, Ethiopian Orthodox, Coptic Orthodox, Greek Orthodox, The Church of Jesus Christ of Latter-day Saints, Seventh-day Adventists, and Jehovah's Witnesses are also present. Catholic sources say the denomination made up 52% of the population of Christians in 2020. The other major denominations are
Episcopal Church (3.5 million members) and the
Presbyterian Church (one million members in 2012). Christianity has grown rapidly in the country over the last two decades. Despite European
missionary activity beginning as early as the mid-19th century, the US
Library of Congress states that "in the early 1990s possibly no more than 10% of southern Sudan's population was
Christian". During this same period, official records of
Sudan claimed that one-quarter of the population of present-day South Sudan practised various
traditional religions while only 5% were Christians. Various scholarly sources, as well as the
US Department of State, stated that a majority of southern Sudanese maintained traditional
animist indigenous beliefs at the start of the 21st century, with Christians remaining a small minority. As in other countries in sub-Saharan Africa, Christianity is often
blended with traditional beliefs. In 2022, the new Catholic bishop of
Rumbek,
Christian Carlassare, observed that while more than half the population of South Sudan is Christian, "Christianity is often no more than skin deep" and "hasn't grown roots in the life of the population". Many religious organisations function as a source of stability, community, humanitarian aid, and refuge in the absence of government institutions, with Christian and Muslim religious leaders actively involved in peacebuilding and socioeconomic development. Muslims are relatively well integrated into South Sudanese society and represented in government; Muslim religious leaders are present in all major political ceremonies as well as peace negotiations. Islamic private schools are maintained with little government involvement, while many secondary institutions include Islamic theology in their curricula. In 2011, inaugural
South Sudanese President
Salva Kiir, a Roman Catholic, said that South Sudan would be a nation that respects
freedom of religion. The country's transitional constitution provides for separation of religion and state, prohibits religious discrimination, and provides religious groups freedom to worship, assemble, proselytise, own property, receive financial contributions, communicate and publish materials on religious matters, and establish charitable institutions. The library currently employs a staff of over 40 volunteers and maintains a collection of over 13,000 books.
Humanitarian situation In
Pibor County located in the
Jonglei State, in December 2011 and January 2012,
cattle raids led to border clashes that eventually resulted in widespread
ethnic violence, with thousands of deaths and tens of thousands of South Sudanese being displaced, and hundreds of
Médecins Sans Frontières staff went missing. The government declared the area a disaster zone and took control from local authorities.
Violence against women is common in the country, and South Sudan's laws and policies have been criticised as inadequate in offering protection. As of December 2017, an estimated 42% of the South Sudanese population was facing severe security conditions, with most of the affected being young people and children. According to the United Nations, 8.3 million people were in need of humanitarian aid in South Sudan as of January 2021. In 2025, 7.7 million people, or 57% of the population, faced acute food insecurity, with
conflict as the main driver,
Malnutrition also worsened, with 2.3 million children at risk of acute malnutrition, amid access constraints, health service disruptions, and a
cholera outbreak affecting
Upper Nile and
Unity states.
Health South Sudan is acknowledged to have some of the worst health indicators in the world. The under-five
infant mortality rate is 135.3 per 1,000, whilst
maternal mortality is the highest in the world at 2,053.9 per 100,000 live births. According to a 2013 study, South Sudan "probably has the highest
malaria burden in
sub-Saharan Africa".
Refugees As a result of
the war that erupted in December 2013, more than 2.3 million people, one in every five people in South Sudan, were forced to flee their homes. This included about 1.66 million
internally displaced people (IDPs), an estimated 53.4% of whom were children, and nearly 644,900 refugees in neighbouring countries. Some 185,000 IDPs sought refuge in UN Protection of Civilians sites, while around 90% remained outside these locations, either on the move or sheltering elsewhere. In response, UNHCR stepped up its engagement through an inter-agency collaborative approach under the leadership of the Humanitarian Coordinator, and working with the
International Organization for Migration. In early February 2013, UNHCR started distributing relief items outside the UN base in Malakal, South Sudan, which was expected to reach 10,000 people. By January 2025, more than one million people had fled the 2023
war in Sudan for South Sudan. By November 2025, the continued arrivals, alongside returning South Sudanese nationals, placed additional pressure on already strained markets, services, and natural resources, while a prolonged economic crisis sharply reduced household purchasing power. These conditions were further aggravated by disease outbreaks, limited access to health care, and inadequate
water, sanitation, and hygiene services. == Culture ==
