In brief: 8% males 1/2% fem

Color deficiency is mostly an inherited defect of the light receptors with a strong sex linking.
Therefore much more common in males. Some cases of lowered color deficiency can occur in global retinal losses such as advancing diabetes and there are a few rare central nervous system color deficiencies as reported by oliver sacks.
