Indian people or Indians are the citizens and nationals of the Republic of India or people who trace their ancestry to India. While the demonym "Indian" applies to people originating from the present-day India, it was also used as the identifying term for people originating from what is now Bangladesh and Pakistan prior to the Partition of India in 1947. The term "Indian" does not refer to a single ethnic group, but is used as an social construct for the various ethnic groups in or from India.

In 2022, the population of India stood at 1.4 billion people. According to United Nations forecasts, India overtook China as the world's most populous country by the end of April 2023, containing 17.50 percent of the global population. In addition to the Indian population, the Indian overseas diaspora also boasts large numbers, particularly in former British colonies due to the historical Indian indenture system, Arab states of the Persian Gulf, and the Western world.

Industrialisation in Bangladesh received a strong impetus after the partition of India due to labour reforms and new industries. Between 1947 and 1971, East Bengal generated between 70% and 50% of Pakistan's exports. Modern Bangladesh embarked on economic reforms in the late 1970s which promoted free markets and foreign direct investment. By the 1990s, the country had a booming ready-made garments industry. As of 16 March 2024, Bangladesh has the highest number of green garment factories in the world with Leadership in Energy and Environmental Design (LEED) certification from the United States Green Building Council (USGBC), where 80 are platinum-rated, 119 are gold-rated, 10 are silver, and four are without any rating.

Bangladesh is the only nation among the 48 least-developed countries that is almost self-sufficient when it comes to medicine production as local companies meet 98 percent of the domestic demand for pharmaceuticals. Remittances from the large Bangladeshi diaspora became a vital source of foreign exchange reserves. Agriculture in Bangladesh is supported by government subsidies and ensures self-sufficiency in food production. Bangladesh has pursued export-oriented industrialisation.
