Afro Colombians, a hidden problem?

I didn´t know anything about afrocolombian taxes of mortality, education or employability. It´s harder to see how is the country where i live. I thought that in Colombia doesn´t exist the racism because i´d been living in Riohacha, in Riohacha afro-colombians, wayuu natives and citadines live together. When i travel to other cities i didn´t realice that problem, i feel very sad to see this in the 21 century...
