The incidence of [[olfactory groove meningioma]] is approximately 8%–14% of all [[intracranial meningioma]]s

It typically affects adults, with a peak incidence in the sixth and seventh decades of life. It appears to be slightly more common in women than in men.

There are also some known risk factors for developing meningiomas in general, such as a history of radiation exposure, neurofibromatosis type 2 (a genetic disorder), and certain rare genetic syndromes. However, the specific causes of olfactory groove meningiomas are not well understood at this time.
