South Asia is the southern subregion of Asia, which is defined in both geographical and ethnic-cultural terms. As commonly conceptualized, the modern states of South Asia include Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. South Asia borders East Asia to the northeast, Central Asia to the northwest, West Asia to the west and Southeast Asia to the east. Topographically, it is dominated by the Indian subcontinent and is bounded by the Indian Ocean in the south, and the Himalayas, Karakoram, and Pamir Mountains in the north.

The South Asian Association for Regional Cooperation (SAARC) is an economic cooperation organization in the region which was established in 1985 and includes all eight nations comprising South Asia. South Asia has a total area of 5.2 million (2 million sq.mi), which is 10% of the Asian continent. The population of the region, under the broader definition, is about 2.04 billion or about one-fourth of the world's population, making it both the most populous and the most densely populated geographical region in the world.

In 2022, South Asia had the world's largest populations of Hindus, Muslims, Sikhs, Jains, and Zoroastrians. South Asia alone accounts for 90.47% of Hindus, 95.5% of Sikhs, and 31% of Muslims worldwide, as well as 35 million Christians and 25 million Buddhists.



The history of core South Asia begins with evidence of human activity of Homo sapiens, as long as 75,000 years ago, or with earlier hominids including Homo erectus from about 500,000 years ago. The earliest prehistoric culture have roots in the mesolithic sites as evidenced by the rock paintings of Bhimbetka rock shelters dating to a period of 30,000 BCE or older, as well as neolithic times.

Ancient era

Indus Valley Civilization, Mature Phase (2600-1900 BCE)
Indus Valley civilisation during 2600–1900 BCE, the mature phase

The Indus Valley civilization, which spread and flourished in the northwestern part of South Asia from c. 3300 to 1300 BCE in present-day Pakistan, Northern India and Afghanistan, was the first major civilization in South Asia. A sophisticated and technologically advanced urban culture developed in the Mature Harappan period, from 2600 to 1900 BCE. According to anthropologist Possehl, the Indus Valley civilization provides a logical, if somewhat arbitrary, starting point for South Asian religions, but these links from the Indus religion to later-day South Asian traditions are subject to scholarly dispute.

The Vedic period, named after the Vedic religion of the Indo-Aryans, lasted from c. 1900 to 500 BCE. The Indo-Aryans were Indo-European pastoralists who migrated into north-western India after the collapse of the Indus Valley Civilization, Linguistic and archaeological data show a cultural change after 1500 BCE, with the linguistic and religious data clearly showing links with Indo-European languages and religion. By about 1200 BCE, the Vedic culture and agrarian lifestyle were established in the northwest and northern Gangetic plain of South Asia. Rudimentary state-forms appeared, of which the Kuru-Pañcāla union was the most influential. The first recorded state-level society in South Asia existed around 1000 BCE. In this period, states Samuel, emerged the Brahmana and Aranyaka layers of Vedic texts, which merged into the earliest Upanishads. These texts began to ask the meaning of a ritual, adding increasing levels of philosophical and metaphysical speculation, or "Hindu synthesis".

Increasing urbanisation of South Asia between 800 and 400 BCE, and possibly the spread of urban diseases, contributed to the rise of ascetic movements and of new ideas which challenged the orthodox Brahmanism. These ideas led to Sramana movements, of which Mahavira (c. 549–477 BCE), proponent of Jainism, and Buddha (c. 563 – c. 483), founder of Buddhism, was the most prominent icons.

The Greek army led by Alexander the Great stayed in the Hindu Kush region of South Asia for several years and then later moved into the Indus valley region. Later, the Maurya Empire extended over much of South Asia in the 3rd century BCE. Buddhism spread beyond south Asia, through northwest into Central Asia. The Bamiyan Buddhas of Afghanistan and the edicts of Aśoka suggest that the Buddhist monks spread Buddhism (Dharma) in eastern provinces of the Seleucid Empire, and possibly even farther into West Asia. The Theravada school spread south from India in the 3rd century BCE, to Sri Lanka, later to Southeast Asia. Buddhism, by the last centuries of the 1st millennium BCE, was prominent in the Himalayan region, Gandhara, Hindu Kush region and Bactria.

From about 500 BCE through about 300 CE, the Vedic-Brahmanic synthesis or "Hindu synthesis" continued. Classical Hindu and Sramanic (particularly Buddhist) ideas spread within South Asia, as well as outside South Asia. The Gupta Empire ruled over a large part of the region between the 4th and 7th centuries, a period that saw the construction of major temples, monasteries and universities such as the Nalanda. During this era, and through the 10th century, numerous cave monasteries and temples such as the Ajanta Caves, Badami cave temples and Ellora Caves were built in South Asia.

Medieval era

Islam came as a political power in the fringe of South Asia in 8th century CE when the Arab general Muhammad bin Qasim conquered Sindh, and Multan in Southern Punjab, in modern-day Pakistan. By 962 CE, Hindu and Buddhist kingdoms in South Asia were under a wave of raids from Muslim armies from Central Asia. Among them was Mahmud of Ghazni, who raided and plundered kingdoms in north India from east of the Indus river to west of Yamuna river seventeen times between 997 and 1030. Mahmud of Ghazni raided the treasuries but retracted each time, only extending Islamic rule into western Punjab.

The wave of raids on north Indian and western Indian kingdoms by Muslim warlords continued after Mahmud of Ghazni, plundering and looting these kingdoms. The raids did not establish or extend permanent boundaries of their Islamic kingdoms. The Ghurid Sultan Mu'izz al-Din Muhammad began a systematic war of expansion into North India in 1173. He sought to carve out a principality for himself by expanding the Islamic world, and thus laid the foundation for the Muslim kingdom that became the Delhi Sultanate. Some historians chronicle the Delhi Sultanate from 1192 due to the presence and geographical claims of Mu'izz al-Din in South Asia by that time.

The Delhi Sultanate covered varying parts of South Asia and was ruled by a series of dynasties: Mamluk, Khalji, Tughlaq, Sayyid and Lodi dynasties. Muhammad bin Tughlaq came to power in 1325, launched a war of expansion and the Delhi Sultanate reached it largest geographical reach over the South Asian region during his 26-year rule. A Sunni Sultan, Muhammad bin Tughlaq persecuted non-Muslims such as Hindus, as well as non-Sunni Muslims such as Shia and Mahdi sects.

Revolts against the Delhi Sultanate sprang up in many parts of South Asia during the 14th century. In the northeast, the Bengal Sultanate became independent in 1346 CE. It remained in power through the early 16th century. The state religion of the sultanate was Islam. In South India, the Hindu Vijayanagara Empire came to power in 1336 and persisted until the middle of the 16th century. It was ultimately defeated and destroyed by an alliance of Muslim Deccan sultanates at the battle of Talikota.

About 1526, the Punjab governor Dawlat Khan Lodī reached out to the Mughal Babur and invited him to attack Delhi Sultanate. Babur defeated and killed Ibrahim Lodi in the Battle of Panipat in 1526. The death of Ibrahim Lodi ended the Delhi Sultanate, and the Mughal Empire replaced it.

Modern era

The modern history period of South Asia, that is 16th-century onwards, witnessed the establishment of the Mughal empire, with Sunni Islam theology. The first ruler was Babur had Turco-Mongol roots and his realm included the northwest and Indo-Gangetic Plain regions of South Asia. The southern and northeastern regions of South Asia were largely under Hindu kings such as those of Vijayanagara Empire and Ahom kingdom, with some regions such as parts of modern Telangana and Andhra Pradesh under local Sultanates namely Deccan sultanates.

The Mughal Empire continued its wars of expansion after Babur's death. With the fall of the Rajput kingdoms and Vijayanagara, its boundaries encompassed almost the entirety of the Indian subcontinent. The Mughal Empire was marked by a period of artistic exchanges and a Central Asian and South Asian architecture synthesis, with remarkable buildings such as the Taj Mahal.

However, this time also marked an extended period of religious persecution. Two of the religious leaders of Sikhism, Guru Arjan and Guru Tegh Bahadur were arrested under orders of the Mughal emperors after their revolts and were executed when they refused to convert to Islam. Religious taxes on non-Muslims called jizya were imposed. Buddhist, Hindu and Sikh temples were desecrated. However, not all Muslim rulers persecuted non-Muslims. Akbar, a Mughal ruler for example, sought religious tolerance and abolished jizya.

After the death of Aurangzeb and the collapse of the Mughal Empire, which marks the beginning of modern India, in the early 18th century, it provided opportunities for the Marathas, Sikhs, Mysoreans and Nawabs of Bengal to exercise control over large regions of the Indian subcontinent. By the mid-18th century, India was a major proto-industrializing region.

Maritime trading between South Asia and European merchants began after the Portuguese explorer Vasco da Gama returned to Europe. British, French, Portuguese colonial interests struck treaties with these rulers and established their trading ports. In northwest South Asia, a large region was consolidated into the Sikh Empire by Ranjit Singh. After the defeat of the Nawab of Bengal and Tipu Sultan and his French allies, the British Empire expanded their control to the Hindu Kush region. By the 19th century, British traders had conquered much of South Asia using divide-and-rule tactics, with the region experiencing significant de-industrialisation in its first few decades of British rule. Control of the region was transferred to the British government after the Indian Rebellion of 1857, with the British cracking down to some extent afterwards. An increase of famines and extreme poverty characterised the colonial period, though railways built with British technology eventually provided crucial famine relief by increasing food distribution throughout India. Introduction of Western political thought inspired a growing Indian intellectual movement. By the 20th century, the British rule begin to be challenged by the Indian National Congress under the leadership of Mahatma Gandhi to seek full independence from the British rule.

Britain, under pressure from Indian freedom fighters, increasingly gave self-rule to British India. By the 1940s, two rival camps emerged among independence activists: those who favored a separate nation for Indian Muslims, and those who wanted a united India. As World War II raged, over 2 million Indians fought for Britain. After the war, the process of independence took place and Britain granted independence to the vast majority of South Asians in 1947, though this coincided with the partition of India into a Hindu-majority India and a Muslim-majority Pakistan, which resulted in significant violence and hardened religious divides in the region for some months.

Contemporary era

India and Pakistan clashed several times in the decades after Independence, with disputes over Kashmir playing a significant role. In 1971, the eastern half of Pakistan seceded with help from India and became the People's Republic of Bangladesh after the traumatic Bangladesh Liberation War. This, along with India and Pakistan gaining nuclear weapons soon afterwards, increased tensions between the two countries. The Cold War decades also contributed to the divide, as Pakistan aligned with the West and India with the Soviet Union; modern legacies of this divide include the majority of India's modern-day weaponry being Russian in origin.

Pakistan has been beset with terrorism, economic issues and military dominance of its government since Independence, with none of its Prime Ministers having completed a full 5-year term in office. India has grown significantly, having slashed its rate of extreme poverty to below 20%. Bangladesh, having struggled greatly for decades due to conflict with and economic exploitation by Pakistan, is now one of the fastest-growing countries in the region, beating India in terms of GDP per capita. Afghanistan has gone through several invasions and Islamist regimes, with many of its refugees having gone to Pakistan and other parts of South Asia and bringing back cultural influences such as cricket. Religious nationalism has grown across the region, with human rights violations causing millions of Hindus and Christians to flee Pakistan and Bangladesh, and Hindu nationalism having grown in India with the election of the Bharatiya Janata Party in 2014. A recent phenomenon has been that of India and China fighting on their border, as well as vying for dominance of South Asia, with China able to use its superior economy to attract countries surrounding India.


According to Saul Cohen, early colonial era strategists treated South Asia with East Asia, but in reality, the South Asia region excluding Afghanistan is a distinct geopolitical region separated from other nearby geostrategic realms, one that is geographically diverse. The region is home to a variety of geographical features, such as glaciers, rainforests, valleys, deserts, and grasslands that are typical of much larger continents. It is surrounded by three water bodies – the Bay of Bengal, the Indian Ocean and the Arabian Sea – and has acutely varied climate zones. The tip of the Indian Peninsula had the highest quality pearls.

Indian Plate

Most of this region is resting on the Indian Plate, the northerly portion of the Indo-Australian Plate, separated from the rest of the Eurasian Plate. The Indian Plate includes most of South Asia, forming a land mass which extends from the Himalayas into a portion of the basin under the Indian Ocean, including parts of South China and Eastern Indonesia, as well as Kunlun and Karakoram ranges, and extending up to but not including Ladakh, Kohistan, the Hindu Kush range, and Balochistan. It may be noted that geophysically the Yarlung Tsangpo River in Tibet is situated at the outside the border of the regional structure, while the Pamir Mountains in Tajikistan are situated inside that border.

The Indian subcontinent formerly formed part of the supercontinent Gondwana, before rifting away during the Cretaceous period and colliding with the Eurasian Plate about 50–55 million years ago and giving birth to the Himalayan range and the Tibetan plateau. It is the peninsular region south of the Himalayas and Kuen Lun mountain ranges and east of the Indus River and the Iranian Plateau, extending southward into the Indian Ocean between the Arabian Sea (to the southwest) and the Bay of Bengal (to the southeast).

The climate of this vast region varies considerably from area to area from tropical monsoon in the south to temperate in the north. The variety is influenced by not only the altitude but also by factors such as proximity to the seacoast and the seasonal impact of the monsoons. Southern parts are mostly hot in summers and receive rain during monsoon periods. The northern belt of Indo-Gangetic plains also is hot in summer, but cooler in winter. The mountainous north is colder and receives snowfall at higher altitudes of Himalayan ranges.

As the Himalayas block the north-Asian bitter cold winds, the temperatures are considerably moderate in the plains down below. For the most part, the climate of the region is called the monsoon climate, which keeps the region humid during summer and dry during winter, and favours the cultivation of jute, tea, rice, and various vegetables in this region.

South Asia is largely divided into four broad climate zones:

Maximum relative humidity of over 80% has been recorded in Khasi and Jaintia Hills and Sri Lanka, while the area adjustment to Pakistan and western India records lower than 20%–30%. Climate of South Asia is largely characterized by monsoons. South Asia depends critically on monsoon rainfall. Two monsoon systems exist in the region:

  • The summer monsoon: Wind blows from the southwest to most parts of the region. It accounts for 70%–90% of the annual precipitation.
  • The winter monsoon: Wind blows from the northeast. Dominant in Sri Lanka and Maldives.

The warmest period of the year precedes the monsoon season (March to mid June). In the summer the low pressures are centered over the Indus-Gangetic Plain and high wind from the Indian Ocean blows towards the center. The monsoons are the second coolest season of the year because of high humidity and cloud covering. But, at the beginning of June, the jetstreams vanish above the Tibetan Plateau, low pressure over the Indus Valley deepens and the Intertropical Convergence Zone (ITCZ) moves in. The change is violent. Moderately vigorous monsoon depressions form in the Bay of Bengal and make landfall from June to September.

Climate change in South Asia is causing a range of challenges including sea level rise, cyclonic activity, and changes in ambient temperature and precipitation patterns.

South Asian Language Families
Ethno-linguistic distribution map of South Asia

There are numerous languages in South Asia. The spoken languages of the region are largely based on geography and shared across religious boundaries, but the written script is sharply divided by religious boundaries. In particular, Muslims of South Asia such as in Afghanistan and Pakistan use the Arabic alphabet and Persian Nastaliq. Till 1952, Muslim-majority Bangladesh (then known as East Pakistan) also mandated only the Nastaliq script, but after that adopted regional scripts and particularly Bengali, after the Language Movement for the adoption of Bengali as the official language of the then East Pakistan. Non-Muslims of South Asia, and some Muslims in India, on the other hand, use scripts such as those derived from Brahmi script for Indo-European languages and non-Brahmi scripts for Dravidian languages and others.

The Nagari script has been the primus inter pares of the traditional South Asian scripts. The Devanagari script is used for over 120 South Asian languages, including Hindi, Marathi, Nepali, Pali, Konkani, Bodo, Sindhi and Maithili among other languages and dialects, making it one of the most used and adopted writing systems in the world. The Devanagari script is also used for classical Sanskrit texts.

The largest spoken language in this region is Hindustani language, followed by Bengali, Telugu, Tamil, Marathi, Gujarati, Kannada, and Punjabi. In the modern era, new syncretic languages developed in the region such as Urdu that are used by the Muslim community of northern South Asia (particularly Pakistan and northern states of India). The Punjabi language spans three religions: Islam, Hinduism, and Sikhism. The spoken language is similar, but it is written in three scripts. The Sikh use Gurmukhi alphabet, Muslim Punjabis in Pakistan use the Nastaliq script, while Hindu Punjabis in India use the Gurmukhi or Nāgarī script. The Gurmukhi and Nagari scripts are distinct but close in their structure, but the Persian Nastaliq script is very different.

Sino-Tibetan languages are spoken across northern belts of the region in the Himalayan areas, often using the Tibetan script. These languages are predominantly spoken in Bhutan and Nepal as well as parts of Burma and northern India in the state of Sikkim and the Ladakh region. The national language of Bhutan is Dzongkha, while Lepcha, Limbu, Gurung, Magar, Rai, Newari, Tamang, Tshangla, Thakali and Sikkimese are also spoken in Bhutan, Nepal and Sikkim, and Ladakhi is spoken in Ladakh. Both Buddhism and Bon are often predominant in areas where these languages are present. Some areas in Gilgit-Baltistan also speak Balti language, however speakers write with the Urdu script. The Tibetan script fell out of use in Pakistani Baltistan hundreds of years ago upon the region's adoption of Islam

English, with British spelling, is commonly used in urban areas and is a major economic lingua franca of South Asia.


Religious Diversity in South Asia (2)
Religious Diversity in South Asia by National Subdivision

Circle frame-1.svg

Religion in British India 1871–1872 Census (includes modern-day India, Bangladesh, most of Pakistan and coastal Myanmar))      Hinduism (73.07%)     Islam (21.45%)     Buddhism and Jainism (1.49%)     Sikhism (0.62%)     Christianity (0.47%)     Others (2.68%)     Religion not known (0.22%)

In 2010, South Asia had the world's largest population of Hindus, about 510 million Muslims, over 27 million Sikhs, 35 million Christians and over 25 million Buddhists. Hindus make up about 68 percent or about 900 million and Muslims at 31 percent or 510 million of the overall South Asia population, while Buddhists, Jains, Christians and Sikhs constitute most of the rest. The Hindus, Buddhists, Jains, Sikhs and Christians are concentrated in India, Nepal, Sri Lanka and Bhutan, while the Muslims are concentrated in Afghanistan (99%), Bangladesh (90%), Pakistan (96%) and Maldives (100%). With all major religions practised in the subcontinent, South Asia is known for its religious diversity and one of the most religiously diverse regions on earth.

Indian religions are the religions that originated in the Indian subcontinent; namely Hinduism, Jainism, Buddhism and Sikhism. The Indian religions are distinct yet share terminology, concepts, goals and ideas, and from South Asia spread into East Asia and southeast Asia. Early Christianity and Islam were introduced into coastal regions of South Asia by merchants who settled among the local populations. Later Sindh, Balochistan, and parts of the Punjab region saw conquest by the Arab caliphates along with an influx of Muslims from Persia and Central Asia, which resulted in spread of both Shia and Sunni Islam in parts of northwestern region of South Asia. Subsequently, under the influence of Muslim rulers of the Islamic sultanates and the Mughal Empire, Islam spread in South Asia. About one-third of the world's Muslims are from South Asia.

South Asian culture, also known as Desi culture, is a mixture of several cultures in and around the Indian subcontinent. Ancient South Asian culture was primarily based in Hinduism, which itself formed as a mixture of Vedic religion and indigenous traditions, and later Buddhist influences. From the medieval era onwards, influences from the Muslim world (particularly Central Asia and the Middle East) and then Europe (primarily British) also became prevalent.

South Asian culture has influenced other parts of Asia, particularly Southeast Asia (see Greater India).


Cricket is the most popular sport in South Asia, with 90% of the sport's worldwide fans being in the Indian subcontinent. There are also some traditional games, such as kabaddi and kho-kho, which are played across the region and officially at the South Asian Games and Asian Games; the leagues created for these traditional sports (such as Pro Kabaddi League and Ultimate Kho Kho) are some of the most-watched sports competitions in the region.


South Asian cinema refers to the cinema of Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. The broader terms Asian cinema, Eastern cinema and Oriental cinema in common usage often encompass South Asia as well as East Asia and Southeast Asia.

Cinema is prominent in South Asia, with the Bollywood (representing the most-spoken language in the region of Hindi) and South Indian film industries being the most dominant. Pakistan's Lollywood also is growing, while historically, Bengali cinema was highly acclaimed by international film circles.

Eastern World
The Far East as a cultural block includes East Asia (green), Southeast Asia (blue) and South Asia (orange).


South Asian music comprises a range of prominent musical genres and styles that are unique to the countries in and around the Indian subcontinent. This subregion of Asia includes countries such as Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka, with each region one possessing its own distinct musical traditions. South Asian styles of music reflect a diverse range of local customs, regional languages and historical traditions, that have shaped the musical practices which are still seen today. Throughout history, South Asian musicians have emulated religious and spiritual beliefs into their compositions, resulting in the creation of musical styles such as Qawwali, Ghazal and Hindustani classical music. The development of forms of mass media in the 1980s and 1990s contributed to a new type of South Asian musical culture, as the rise of cinema and television resulted in the popularity of genres such as Bollywood and Lollywood. As a result of social media and modern streaming networks, folk and ritual music styles are still widely appreciated today, with many modern artists taking inspiration from the classical traditions that defined the history of South Asian music.


South Asian cuisine, includes the traditional cuisines from the modern-day South Asian republics of Bangladesh, India, Maldives, Nepal, Pakistan and Sri Lanka, also sometimes including the kingdom of Bhutan and the emirate of Afghanistan. Also sometimes known as Desi cuisine, it has been influenced by and also has influenced other Asian cuisines beyond the Indian subcontinent.

Staples and common ingredients

An assortment of spices and herbs. Spices are an indispensable food ingredient in much of the subcontinent.

Chapati, a type of flat bread, is a common part of meals to be had in many parts of the subcontinent. Other staples from many of the cuisines include rice, roti made from atta flour, and beans.

Foods in this area of the world are flavoured with various types of chilli, black pepper, cloves, and other strong herbs and spices along with the flavoured butter ghee. Ginger is an ingredient that can be used in both savory and sweet recipes in cuisines from the subcontinent. Chopped ginger is fried with meat and pickled ginger is often an accompaniment to boiled rice. Ginger juice and ginger boiled in syrup are used to make desserts. Turmeric and cumin are often used to make curries.

Common meats include lamb, goat, fish, chicken and beef. Beef is less common in India, Nepal and Sri Lanka than in other South Asian cuisines because cattle have a special place in Dharmic religions. Prohibitions against beef extend to the meat of (water) buffalo and yaks to some extent. Pork is considered as a taboo food item by all Muslims and is not taboo but avoided by many Hindus, though it is commonly eaten in some regions like Northeast India and Goa where Christianity is wide-spread. A variety of very sweet desserts which use dairy products is also found in cuisines of the subcontinent. The main ingredients in desserts of the subcontinent are reduced milk, ground almonds, lentil flour, ghee and sugar. Kheer is a dairy-based rice pudding, a common dessert.

GDP per capita development in South Asia

India is the largest economy in the region (US$ 4.11 trillion) and makes up almost 80% of the South Asian economy; it is the world's 5th largest in nominal terms and 3rd largest by purchasing power adjusted exchange rates (US$ 14.26 trillion). India is the member of G-20 major economies and BRICS from the region. It is the fastest-growing major economy in the world and one of the world's fastest registering a growth of 7.2% in FY 2022–23.

India is followed by Bangladesh, which has a GDP of ($446 billion). It has the fastest GDP growth rate in Asia. It is one of the emerging and growth-leading economies of the world, and is also listed among the Next Eleven countries. It is also one of the fastest-growing middle-income countries. It has the world's 33rd largest GDP in nominal terms and is the 25th largest by purchasing power adjusted exchange rates ($1.476 trillion). Bangladesh's economic growth was 6.4% in 2022. The next one is Pakistan, which has an economy of ($340 billion). Next is Sri Lanka, which has the 2nd highest GDP per capita and the 4th largest economy in the region. According to a World Bank report in 2015, driven by a strong expansion in India, coupled with favorable oil prices, from the last quarter of 2014 South Asia became the fastest-growing region in the world.

Certain parts of South Asia are significantly wealthier than others; the four Indian states of Maharashtra, Tamil Nadu, Gujarat and Karnataka are projected to account for almost 50% of India's GDP by 2030, while the five South Indian states comprising 20% of India's population are expected to contribute 35% of India's GDP by 2030.

One of the key challenges in assessing the quality of education in South Asia is the vast range of contextual difference across the region, complicating any attempt to compare between countries. In 2018, 11.3 million children at the primary level and 20.6 million children at the lower secondary level were out-of-school in South Asia, while millions of children completed primary education without mastering the foundational skills of basic numeracy and literacy.

According to UNESCO, 241 million children between six and fourteen years or 81 percent of the total were not learning in Southern and Central Asia in 2017. Only sub-Saharan Africa had a higher rate of children not learning. Two-thirds of these children were in school, sitting in classrooms. Only 19% of children attending primary and lower secondary schools attain a minimum proficiency level in reading and mathematics. According to a citizen-led assessment, only 48% in Indian public schools and 46% of children in Pakistan public schools could read a class two level text by the time they reached class five. This poor quality of education in turn has contributed to some of the highest drop-out rates in the world, while over half of the students complete secondary school with acquiring requisite skills.

In South Asia, classrooms are teacher-centred and rote-based, while children are often subjected to corporal punishment and discrimination. Different South Asian countries have different education structures. While by 2018 India and Pakistan has two of the most developed and increasingly decentralised education systems, Bangladesh still had a highly centralised system, and Nepal is in a state of transition from a centralized to a decentralized system. In most South Asian countries children's education is theoretically free; the exceptions are the Maldives, where there is no constitutionally guaranteed free education, as well as Bhutan and Nepal, where fees are charged by primary schools. But parents are still faced with unmanageable secondary financial demands, including private tuition to make up for the inadequacies of the education system.

The larger and poorer countries in the region, like India and Bangladesh, struggle financially to get sufficient resources to sustain an education system required for their vast populations, with an added challenge of getting large numbers of out-of-school children enrolled into schools. Their capacity to deliver inclusive and equitable quality education is limited by low levels of public finance for education, while the smaller emerging middle-income countries like Sri Lanka, Maldives and Bhutan have been able to achieve universal primary school completion, and are in a better position to focus on quality of education.

Children's education in the region is also adversely affected by natural and human-made crises including natural hazards, political instability, rising extremism and civil strife that makes it difficult to deliver educational services. Afghanistan and India are among the top ten countries with the highest number of reported disasters due to natural hazards and conflict. The precarious security situation in Afghanistan is a big barrier in rolling out education programmes on a national scale.

According to UNICEF, girls face incredible hurdles to pursue their education in the region, while UNESCO estimated in 2005 that 24 million girls of primary-school age in the region were not receiving any formal education. Between 1900 and 2005, most of the countries in the region had shown progress in girls' education with Sri Lanka and the Maldives significantly ahead of the others, while the gender gap in education has widened in Pakistan and Afghanistan. Bangladesh made the greatest progress in the region in the period increasing girls' secondary school enrolment from 13 percent to 56 percent in ten years.

With about 21 million students in 700 universities and 40 thousand colleges India had one of the largest higher education systems in the world in 2011, accounting for 86 percent of all higher-level students in South Asia. Bangladesh (two million) and Pakistan (1.8 million) stood at distant second and third positions in the region. In Nepal (390 thousand) and Sri Lanka (230 thousand) the numbers were much smaller. Bhutan with only one university and Maldives with none hardly had between them about 7000 students in higher education in 2011. The gross enrolment ratio in 2011 ranged from about 10 percent in Pakistan and Afghanistan to above 20 percent in India, much below the global average of 31 percent.

Health and nutrition

According to World Health Organization (WHO), South Asia is home to two out of the three countries in the world still affected by polio, Pakistan and Afghanistan, with 306 & 28 polio cases registered in 2014 respectively. Attempts to eradicate polio have been badly hit by opposition from militants in both countries, who say the program is cover to spy on their operations. Their attacks on immunization teams have claimed 78 lives since December 2012.

The World Bank estimates that India is one of the highest ranking countries in the world for the number of children suffering from malnutrition. The prevalence of underweight children in India is among the highest in the world and is nearly double that of Sub Saharan Africa with dire consequences for mobility, mortality, productivity, and economic growth.

According to the World Bank, 64% of South Asians lived in rural areas in 2022. In 2008, about 75% of South Asia's poor lived in rural areas and most relied on agriculture for their livelihood according to the UN's Food and Agricultural Organisation.

In 2021, approximately 330 million people in the region were malnourished. A 2015 report says that Nepal reached both the WFS target as well as MDG and is moving towards bringing down the number of undernourished people to less than 5% of the population. Bangladesh reached the MDG target with the National Food Policy framework – with only 16.5% of the population undernourished. In India, the malnourished comprise just over 15 percent of the population. While the number of malnourished people in the neighborhood has shown a decline over the last 25 years, the number of under-nourished in Pakistan displays an upward trend. There were 28.7 million hungry in Pakistan in the 1990s – a number that has steadily increased to 41.3 million in 2015 with 22% of the population malnourished. Approximately 194.6 million people are undernourished in India, which accounts for the highest number of people suffering from hunger in any single country.

The 2006 report stated, "the low status of women in South Asian countries and their lack of nutritional knowledge are important determinants of high prevalence of underweight children in the region". Corruption and the lack of initiative on the part of the government has been one of the major problems associated with nutrition in India. Illiteracy in villages has been found to be one of the major issues that need more government attention. The report mentioned that although there has been a reduction in malnutrition due to the Green Revolution in South Asia, there is concern that South Asia has "inadequate feeding and caring practices for young children".

India is a secular federative parliamentary republic with the prime minister as head of government. With the most populous functional democracy in world and the world's longest written constitution, India has been stably sustaining the political system it adopted in 1950 with no regime change except that by a democratic election. India's sustained democratic freedoms are unique among the world's newer establishments. Since the formation of its republic abolishing British law, it has remained a democracy with civil liberties, an active Supreme Court, and a largely independent press. India leads region in Democracy Index. It has a multi-party system in its internal regional politics whereas alternative transfer of powers to alliances of Indian left-wing and right-wing political parties in national government provide it with characteristics of a two-party state. India has been facing notable internal religious conflicts and separatism however consistently becoming more and more stable with time.

The foundation of Pakistan lies in the Pakistan movement which began in colonial India based on Islamic nationalism. Pakistan is a federal parliamentary Islamic republic and was the world's first country to adopt Islamic republic system to modify its republican status under its otherwise secular constitution in 1956. Pakistan's governance is one of the most conflicted in the world. The military rule and the unstable governments in Pakistan have become a concern for the South Asian region. Out of 22 appointed Pakistani Prime ministers, none of them have ever been able to complete a full term in office. The nature of Pakistani politics can be characterized as a multi-party system.

The unitary semi-presidential constitutional republic of Sri Lanka is the oldest sustained democracy in Asia. Tensions between the Sinhalese and the Tamils led to the emergence of the Liberation Tigers of Tamil Eelam, a separatist Sri Lankan Tamil militant group and the outbreak of the Sri Lankan Civil War. The war, which ended in 2009, would undermine the country's stability for more than two and a half decades. Sri Lanka, however, has been leading the region in HDI with per capita GDP well ahead of India, Pakistan and Bangladesh. Sri Lanka has a multi-party system, and the political situation in Sri Lanka has been dominated by an increasingly assertive ideology of Sinhalese nationalism.

Bangladesh is a unitary parliamentary republic. The law of Bangladesh defines it as Islamic as well as secular. The nature of Bangladeshi politics can be characterized as a multi-party system. Bangladesh is a unitary state and parliamentary democracy. Bangladesh also stands out as one of the few Muslim-majority democracies. "It is a moderate and generally secular and tolerant — though sometimes this is getting stretched at the moment — alternative to violent extremism in a very troubled part of the world", said Dan Mozena, the U.S. ambassador to Bangladesh. Although Bangladesh's legal code is secular, more citizens are embracing a conservative version of Islam, with some pushing for sharia law, analysts say. Experts say that the rise in conservatism reflects the influence of foreign-financed Islamic charities and the more austere version of Islam brought home by migrant workers in Persian Gulf countries.

By the 18th century, the Hindu Gorkha Kingdom achieved the unification of Nepal. Hinduism became the state religion and Hindu laws were formulated as national policies. A small oligarchic group of Gorkha region based Hindu Thakuri and Chhetri political families dominated the national politics, military and civic affairs until the abdication of the Rana dynasty regime and establishment of Parliamentary democratic system in 1951, which was twice suspended by Nepalese monarchs, in 1960 and 2005. It was the last Hindu state in world before becoming a secular democratic republic in 2008. The country's modern development suffered due to the various significant events like the 1990 Nepalese revolution, 1996–2006 Nepalese Civil War, April 2015 Nepal earthquake and the 2015 Nepal blockade by India leading to the grave 2015–2017 Nepal humanitarian crisis. There is also a huge turnover in the office of the Prime Minister of Nepal leading to serious concerns of political instability. The country has been ranked one of the poor countries in terms of GDP per capita but it has one of the lowest levels of hunger problem in South Asia. When the stability of the country ensured as late as recent, it has also made considerable progress in development indicators outpacing many other South Asian states.

Afghanistan has been a unitary theocratic Islamic emirate since 2021. Afghanistan has been suffering from one of the most unstable regimes on earth as a result of multiple foreign invasions, civil wars, revolutions and terrorist groups. Persisting instability for decades have left the country's economy stagnated and torn and it remains one of the most poor and least developed countries on the planet, leading to the influx of Afghan refugees to neighboring countries like Iran.

Bhutan is a Buddhist state with a constitutional monarchy. The country has been ranked as the least corrupt and most peaceful country in the region, with the most economic freedom, in 2016.

Maldives is a unitary presidential republic with Sunni Islam strictly as the state religion.
