What percentage of people prefer large cities to small towns?

Since its independence, Mexico has defined itself as a mestizo nation, redefining the Spanish Conquest of the Amerindian population as the "painful birth of the Mexican people". As such, the "mestizo" concept has become the identity and culture of the independent country. As an ethnic group, mestizos constitute officially 65-75% of Mexico's population. Other international organizations prefer a lower percentage, close to 60%, that allows for a categorization of 30% of predominantly Amerindians.
