My dad is Jamaica i've been to the island a couple times.....Jamaica's diversity is really overstated, the overwhelming amount of people are African descent or mixed with African descentNo those are locals... Many of the onlookers are locals that cannot afford to participate so they view in the streets. Again, islands have many white people and people of racial mixes. I always laugh when people have a stereotype or certain islands but it's because it is what they are exposed to like say in Brooklyn when they see a hatian or Jamaican. There are reasons you have this misconception but I am not going to get into that.
idk, i'm comparing it to the carnivals in Brooklyn and Aruba that i've been to. in Aruba the tourists are rarely involved in the parade
