Answer:
Norwegians in the Untied States.
Explanation:
Norwegians usually have very fair skin, which shows that they do not have much melanin. In addition, Norway is in a region with little sun compared to the US.
Melanin is a pigment whose function is to protect DNA against the harmful action of radiation emitted by the sun.
As has been said the Norwegians have little melanin, and the US has a higher incidence of sunlight than Norway. This way, when Norwegians go to the United States they are exposed to all the sun damage and become very susceptible to skin cancer.
