Are you talking about Europe or The United States? Europe: You were put in a concentration camp if you were a Jew, Gay, Russian, POW, Czech, Jehovah Witness. If you weren't viewed as an Aryan, you were put in a concentration camp. United States: After Pearl Harbor, the United States government was scared that the Japanese citizens would commit acts of espionage against The United States. So they rounded up as many Japanese as they could, and detained them in camps.
In concentration camps, since men and women were separated, young children were put in the women's section. However, if the concentration camps were also extermination camps, the children were often murdered upon arrival.
