The 1-year (or active) prevalence in relation to age in people who fulfilled the lifetime prevalence criteria for migraine with aura (at least 2 attacks) or without aura (at least 5 attacks) and who had had at least 1 attack of migraine in the previous year. The 1-year prevalence steeply rises around puberty, continues to rise up to 2 or 3 times higher in females in the reproductive age range, and declines again after 45 to 50 years of age, notably in females. Peak prevalence of active migraine is ~40 years of age with 35% of females and 15% of males affected. Active migraine occurs in ~5% of young children and ~5% of the older people.
