1. The Blacks have lesser number of seats i.e. 8, in the House of Representatives as compared to their population (13%) so a system of reservation should be there for them in US Congress.
2. In case of Hispanics, the need of reservation is somewhat more as the number of their members in the House of Representatives is far less (5) as compared to their population (13%).
3. There is no need of reservation for the Whites as they have already more seats (86) in the House of Representatives as compared to their population (70%).
