Females are the majority of depression sufferers.
About twice as many women suffer from it than men. Manic depression, however, occurs equally between the genders. In most
cases, people ranging from age 13 to age 44 are the main sufferers of depression, especially those born after 1945. Those
with a family history of depression are at an increased risk of developing depression. Depression often co-occurs with medical,
psychiatric, and substance abuse disorders. Marriage can also be associated with depression. Married people and those in long-term
relationships have a somewhat lower rate of clinical depression than those living alone. However, those in unhappy relationships
have the highest rate of depression of the two.
