Colloid cysts account for approximately 2% of primary brain tumors, and the majority of cases are identified in the fourth and fifth decade. Eighty percent of the patients with colloid cyst reported in the literature are aged 30-60 years. Approximately 15-20% of all intraventricular masses are colloid cysts. Colloid cysts develop in the rostral aspect of the third ventricle in the foramen of Monro in 99% of cases, and despite their benign histology, they may carry high risks and neurologic complications, with a mortality reported from 3.1% to 10% in symptomatic cases or 1.2% in total.

This is unknown, since only those with symptoms come to clinic, and many die without knowing. I have read that it affects more men, and that those with congenital forms are more likely to present at age 40-70 years.
