The Centers for Disease Control and Prevention has just released some alarming new statistics that indicate that suicides among young people, and especially young girls, have spiked dramatically in a very short period of time. The rate of suicide for teen girls has reached a 40-year high based on 2015 statistics, and teenage boys and men have also seen a big jump.

Suicide rates increased in excess of 30 percent between 2007 and 2015 for teenage boys and young men, but that’s nothing compared to the jump for girls, with the rate doubling over that same time period.

The suicide rate for all groups has moved around quite a bit over the years, but never have we seen such a dramatic rise over such a short period of time. The suicide rate for females between 15 and 19 was 2.9 per 100,000 people back in 1975, which increased to 3.7 in 1990, declined to 2.4 in 2007, and now has skyrocketed to 5.1 in 2015. For boys the same age, it went from 18.1 in 1990 to 10.8 in 2007, and then jumped to 14.2 two years ago.

“These data show that between 2007 and 2015, there’s substantial increases in suicide rates for both young males and young females,” said Tom Simon, an author of the report and associate director for science in the division of violence protection at the CDC, according to a CNN report. “For young males, there was a 31% increase in suicide rates, and for young females, the suicide rate doubled.”

There were 1,289 suicides among young males in 1975 in the United States, according to CDC statistics. There were 305 suicides for girls 15 to 19 years of age that year. In 2015, that figure is 1,537 for males and 524 for females between 15-19.

“Suicide is a serious public health problem that can have lasting harmful effects on individuals, families, and communities,’ the CDC states. “While its causes are complex and determined by multiple factors, the goal of suicide prevention is simple: Reduce factors that increase risk (i.e. risk factors) and increase factors that promote resilience (i.e. protective factors). Ideally, prevention addresses all levels of influence: individual, relationship, community, and societal. Effective prevention strategies are needed to promote awareness of suicide and encourage a commitment to social change.”

Suicide is a leading cause of death in the United States.

“We know that overall in the US, we’re seeing increases in suicide rates across all age groups,” Simon said according to CNN. “We’re not seeing the same kind of increases among the oldest adults, but we are seeing substantial and sustained increases now for the other age groups really going back to 2000.”
