"latino" is a broad term that comprises what populations in the united states today?

Despite the widespread notion that Latino refers to any Spanish speaking person, Latino actually refers to people from Latin America - Mexicans, Brazilians, Bolivians, Cubans, etc. Many people think Latino and Hispanic are interchangeable, when they in fact are not. Someone who speaks Spanish is Hispanic, but not necessarily Latino, and vice versa. For example, Spanish people from Spain; they are Hispanic, but not Latino. Someone from Brazil is Latino, but not Hispanic. However, someone from Mexico is Hispanic and Latino.

I hope this helps.
