The group that has shown the highest increase in suicide rates is middle-aged men and women, for whom the number of suicides has risen by a horrifying 28.4 percent in a mere decade. The sharpest increase has been among men in their fifties, for whom the number has risen nearly 50 percent since 1999. Now nearly 30 per 100,000 American men in their fifties kill themselves. Suicides are increasing across the board, from college students to the elderly, but the increases for the middle-aged are shocking.
