All people can receive skin cancer regardless of their skin color. People with darker skin have more melanin which protects the skin from UV light but only to a certain extent. People with darker skin are still able to get skin cancer and even sunburnt.

Stratum corneum: 20-30 Dead, horny layers 
Stratum lucidum: Only in thicker layers of skin 
Stratum granulosum: Looks like grain 
Stratum spinosum: Most layers, location of keratinocytes 
Stratum basale: Actively mitoctic stem cells, as cells age they become part of superficial layers. location of melanocytes.

People that live closer to the equator are usually darker skinned and produce a type of melanin called eumelanin. People that live further away from the equator are usually fair skinned and produce a melanin called pheomelanin.

Vitamin D intake is important to regulate calcium and phosphorus absorption, it also helps maintain healthy bones and teeth. If you are deprived of Vitamin D you would be more likely to develop cancer.

Melanocytes are located in the fifth and deepest layer of the epidermis, the Stratum Basale. Melanocytes synthesize melanin which is what's responsible for the complexion of the skin.

Vitamin D is synthesized when the skin is exposed to ultraviolet light. In the epidermis there is a kind of pre-vitamin D and when your skin is exposed, it activates and thus makes its way through the blood stream, to the liver and kidney. There, it becomes activated into vitamin D.

There is a correlation between vitamin D and melanin. Melanin protects the skin against UV light. But by blocking the sun's rays, melanin effects the skin's ability to activate pre-vitamin D. So the more melanin, the less vitamin D you produce.
