| Age | This is the second most common cancer among children, following leukemia. Adult malignant brain tumors are most common after age 60. |
| Gender | Males have higher rates than females. |
| Race & SES* | The incidence rate is higher in Caucasians and higher social classes. |
| Genetics | Certain genetic factors may cause an increased risk of some malignant brain tumors. |
| Occupation | Many occupational and environmental exposures have shown suggestive associations with elevated rates of brain cancer, including radiation, vinyl chloride, and agricultural chemicals. Studies about these associations are still inconclusive. |
| Other | Human Immunodeficiency Virus (HIV) infected individuals have a much increased risk of developing brain lymphoma. |

The age-related incidence is bimodal, usually with an early peak in infancy and childhood, a gradual rise in young adulthood, and a broader, sustained peak during the fifth to eighth decade of life. The expected early childhood peak is absent in Idaho's population. Instead, what is observed is an early middle-age peak in addition to the sustained peak during the fifth to eighth decade of life.
