5. Epidemiology
As many as half a million Americans suffer from SAD, but, thankfully, most people experience a milder form. Moreover, more women than men suffer from SAD. The disorder typically begins early in adulthood, though children and teenagers can also develop seasonal depression. It is less common among older adults.
SAD is more prevalent in the higher latitudes and in regions where cloudy and rainy conditions are common, such as the Pacific Northwest in the United States. As the distance from the equator increases, so does the prevalence of seasonal depression.
