I can help you with that: Both are referred to as "black" (or worse), anywhere they go in the world, and both suffer the effects, prejudice and discrimination of racism - anywhere they go in the world. Another fan fact - your hypothetical Jamaican and Nigerian, are the most likely to type "How does country X treat black people" before deciding whether to visit a country on holiday - something very few other people (if any) do - so there is a lot that binds the Jamaican and Nigerian together - the nonsensical (but very problematic) notion of "race".
