| Age | Melanoma is extremely uncommon before puberty. Rates increase with age. |
| Gender | It occurs more frequently in males than females. |
| Race & SES* | The incidence rate is highest in Caucasians and is uncommon in African Americans. It has an increased incidence in higher income groups. |
| Occupation | Occupations associated with increased sun exposure have a higher incidence. |
| Other | Ultra violet light exposure, especially from blistering sunburns during childhood, is a major risk factor. Melanoma has been on the increase nationally for several decades. People with light skin and individuals with numerous or atypical moles are at increased risk. |

The age-specific incidence rate peaks in the eighth decade of life. The rates for males and females in Idaho are about the same until age 50 when rates for males increased to twice or more the rates for females.
