India among the following countries has the lowest GDP per capita.

The economy of India is the twelfth largest in the world by market exchange rates and the fourth largest in the world by GDP, measured on a purchasing power parity (PPP) basis. The country was under socialist-based policies for an entire generation from the 1950s until the 1980s. The economy was characterised by extensive regulation, protectionism, and public ownership, leading to pervasive corruption and slow growth. Since 1991, continuing economic liberalisation has moved the economy towards a market-based system.
