Thanks @kevin this is a very interesting question. Am from the Caribbean interestingly and is observed a global view of the Caribbean islands being these  notorious death match arenas you may never make it out alive, especially with the various travel advisories issued. Which are most times the farthest from the truth. The hearts of the people from the Caribbean are just as warm and friendly as the Tropical climate we have year round with an extra tip for Tourists and guests. Put it this way, there is good and bad everywhere in the world, but the good always triumph evil, of course not the safest place in the world which the question still stands, where is the safest place in the world?. Rule of thumb stay positive stay on the right and you should be amazingly fine. Relating ethnicity each island has their own ethnic core belief systems, cultures, languages etc. you may just need to visit and see. All countries in the Caribbean are perfect choices but top islands I recommend; Jamaica, Trinidad, Puerto Rico, Barbados, Bahamas off the top my head. There are other great islands too. High tourist seasons are generally December trough April, Mid season May to June & September to November other times are low season. High seasons are best weather conditions, more festivities activities attraction, more crowds, more costs, etc. and it gradually down size as per season until the cycle restarts next year.
