Nepal is a landlocked sovereign nation located in South East Asia. With an area of 147,181 square kilometres (56,827 sq mi) and a population of approximately 27 million (and nearly 2 million absentee workers living abroad), Nepal is the world's 93rd largest country by land mass and the 41st most populous country. It is located in the Himalayas and bordered to the north by the People's Republic of China, and to the south, east, and west by the Republic of India. Specifically, the Indian states of Uttarakhand, Uttar Pradesh, Bihar, West Bengal, and Sikkim border Nepal, while across the Himalayas lies the Tibetan Autonomous Region. Nepal is separated from Bangladesh by the narrow Indian Siliguri Corridor. Kathmandu is the nation's capital and largest metropolis.
The mountainous north of Nepal has eight of the world's ten tallest mountains, including the highest point on Earth, Mount Everest, called Sagarmatha (सगरमाथा) in Nepali. It contains more than 240 peaks over 20,000 ft (6,096 m) above sea level. The southern Terai region is fertile and humid. Lumbini, the birthplace of Lord Gautam Buddha, is located in this region. Lumbini is one of the holiest places of one of the world's great religions, and its remains contain important evidence about the nature of Buddhist pilgrimage centres from as early as the 3rd century BC.
Hinduism is practiced by about 81.3% of Nepalis, making it the country with the highest percentage of Hindus. Buddhism is linked historically with Nepal and is practiced by 16%, Kirat 5.1%, Islam by 4.4%, Christianity 1.4%, and animism 0.4%. A large section of the population, especially in hill region, even though they follow Hindu customs, may identify themselves as both Hindu as well as Buddhists which can be attributed to the syncretic nature of Hinduism and Buddhism in Nepal.
