What age do children notice racial differences?

Answer 1

There is no "set" age when children begin noticing racial differences, in fact, most young children don't seem to notice race at all (or, at least, don't seem to pay much attention to it.)

A child would probably first become aware of racial differences when they notice their parents talking about it, or learn about things like prejudice or Civil Rights at school.

Unfortunately, some children may become the target of racism, which would be another way they discover how people of different races are treated.
