South Asia is the southern subregion of Asia, both a place of rich geography and deep cultural ties. It includes countries such as Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka, with Afghanistan sometimes included. This area is home to over two billion people, which is a quarter of all the people in the world, making it the most crowded part of the world.
The lands of South Asia have seen some of the world's earliest civilisations, like the Indus Valley Civilisation, and have been shaped by many different cultures and religions over thousands of years. Major religions such as Hinduism, Buddhism, Jainism, Islam, Christianity, and Sikhism all have deep roots here.
Today, South Asia is very important in the world. It has the largest numbers of Hindus, Muslims, Sikhs, Jains, and Zoroastrians. The region works together through groups like the South Asian Association for Regional Cooperation (SAARC) to help its countries grow and cooperate. With its mix of history, culture, and people, South Asia remains one of the most fascinating parts of the world.
Definition
The definition of South Asia can be confusing because its borders are not clearly set. Geographically, South Asia is a peninsula resting on the Indian Plate. It is surrounded by the Himalayas to the north, the Hindu Kush to the west, and the Arakanese to the east. To the south, it extends into the Indian Ocean, bordered by the Arabian Sea to the southwest and the Bay of Bengal to the southeast.
Commonly, South Asia includes Bangladesh, India, Pakistan, Nepal, Bhutan, Sri Lanka, and the Maldives. Sometimes Afghanistan is also included, though its classification can vary. Different groups and organizations may have slightly different definitions of what counts as South Asia.
History
Main article: Outline of South Asian history Main article: Timeline of South Asian history
The history of South Asia begins with evidence of human activity over 75,000 years ago. One of the world's earliest civilizations, the Indus Valley Civilisation, flourished here from around 3300 to 1300 BCE. This was followed by the Vedic period, which saw the rise of early religious ideas and the formation of early states.
Later periods include the rise of powerful empires like the Maurya Empire and the Gupta Empire, and the spread of major religions such as Buddhism and Hinduism. In the medieval era, Muslim empires such as the Delhi Sultanate and later the Mughal Empire ruled much of the region.
In modern times, European colonial powers, especially the British, took control of South Asia. This period saw changes in society and economy, leading up to independence movements. In 1947, British rule ended, and the countries of India, Pakistan, and later Bangladesh emerged. Since then, the region has seen growth, conflicts, and changing relationships with other world powers.

South Asia is a diverse region with many types of land, such as glaciers, rainforests, valleys, deserts, and grasslands. It is surrounded by water on three sides—the Bay of Bengal, the Indian Ocean, and the Arabian Sea. The climate varies widely, from tropical in the south to cold in the north, with monsoons bringing rain each year.
Most of South Asia sits on the Indian Plate, a large piece of Earth's crust that moved northward and pushed up the Himalayan range. This plate includes parts of many countries and many different landscapes. The region's weather changes with altitude and distance from the coast, creating many different climate zones. Some areas are very dry, while others are very wet, and the north gets cold winters and snow in the mountains.

South Asia has a large and growing economy, with India being the biggest. India’s economy is worth about US$4.18 trillion, making it the world’s 4th largest economy. India is also one of the fastest-growing economies, growing by 7.2% in 2022–23. Bangladesh follows as the next largest economy in the region, with a GDP of about $446 billion and strong growth as well.
Some parts of South Asia are much wealthier than others. For example, a few states in India are expected to produce nearly half of the country’s total economy by 2030. However, many people in South Asia still live in poverty. About 20% of the region’s people are considered poor, with Afghanistan having the highest percentage. India has made progress in reducing poverty, lifting millions of people out of it over the past years.

Education
See also: History of education in the Indian subcontinent
Education in South Asia faces many challenges due to the region's diverse countries and contexts. In 2018, millions of children were not in school, and many who were in school did not learn basic skills like reading and math. Only a small part of students reached the needed skill level.
Schools in South Asia often use strict teaching methods, and students may face unfair treatment. Each country has its own education system, and while some offer free education, others charge fees. Large countries like India and Bangladesh struggle to provide enough resources for all their students. Smaller countries like Sri Lanka, the Maldives, and Bhutan have better access to primary education but focus more on improving quality.
Girls often have a harder time getting an education, though some countries have made progress in recent years. India has the largest higher education system in the region, with many students attending universities and colleges. Other countries have smaller numbers of students in higher education.

Health and nutrition
South Asia faces significant health and nutrition challenges. Many children in the region suffer from malnutrition, with India having one of the highest numbers of malnourished children in the world. Rural areas are particularly affected, with most people relying on agriculture for their living.
Countries like Nepal and Bangladesh have made progress in reducing hunger, but Pakistan has seen an increase in the number of undernourished people over the past few decades. Improving nutrition requires attention to factors such as education, women's status, and government policies.
Governance and politics
