The Equality Trust has explained wealth gap in simple terms: “Wealth refers to the total amount of assets of an individual or household. This may include financial assets, such as bonds and stocks, property and private pension rights. Wealth inequality therefore refers to the unequal distribution of assets in a group of people.”
How unequal is India, when it comes to wealth? Quite unequal, as pointed out in this article by The Hindu. These clear graphs help put wealth inequality in perspective.
