Uruguay's Demographics

In my mind I stereotype all of the people in Latin American as being the same race even though they are all from very different countries.  I was surprised to learn that Uruguay is 88 percent white, eight percent mestizo and four percent black according to the CIA World Factbook.  The indigenous population is virtually nonexistent.  I think that this is really interesting and means that the problems that other Latin American countries face with the discrimination of indigenous people are not a big problem in Uruguay.  This information will make me more hesitant to generalize about the people who make up all the different and unique countries in Latin America.
