West Bengal is one of the most culturally and ethnically diverse states of India. The people of West Bengal inherit their identity and aspiration from the larger Indian mosaic and from civilizations that go beyond shores and centuries. Different ethnicity, religion, languages and culture adds to this rich landscape and glorifies its people instead of separating them. West Bengal is the nation's fourth most populous as well as the seventh-most populous sub-national entity in the world, with over 91 million inhabitants. A major agricultural producer, West Bengal is the sixth-largest contributor to India's gross domestic product.
