While nostalgia for the 1990s is prevalent, the reality for teenagers during that decade was marked by significant social problems, including high rates of teen pregnancy, substance use, and violence. In stark contrast, today's teenagers exhibit dramatically lower rates of these risky behaviors, representing a substantial, yet largely uncelebrated, public health success.

In 1991, the teen birth rate stood at a record high of 61.8 births per 1,000 girls aged 15-19. President Bill Clinton even declared the "epidemic of teen pregnancies" America's "most serious social problem" in his 1995 State of the Union address. The fear extended to public safety, with juvenile arrests peaking in 1996 at nearly 2.7 million, fueled by a "superpredator" panic. Data from 1995 indicates that half of high school students drank alcohol, 35 percent smoked cigarettes, 40 percent had tried marijuana, 10 percent had carried a weapon to school, and approximately 6 percent of teenage girls were pregnant in any given year. The teen suicide rate for boys also reached a record high in 1990.

A Dramatic Decline in Risky Behaviors

Since these peaks, a remarkable turnaround has occurred. By 2025, the U.S. teen birth rate had fallen to 11.7 births per 1,000 girls aged 15 to 19, an 81 percent decrease from its 1991 high and the lowest figure ever recorded. This downward trend has been consistent for over three decades. The decline is not limited to pregnancy; nearly every risky behavior prevalent in the 1990s has seen a significant collapse. For instance, the teen birth rate alone dropped 7 percent in 2025.

The reduction in teen births can be attributed to two primary factors: a decrease in sexual activity among teens and improved contraceptive use. The proportion of high schoolers who had ever had sex fell from 54 percent in 1991 to 32 percent in 2023. Research indicates that improved contraceptive use, including a sevenfold increase in the use of long-acting IUDs and implants among teens, drove most of the pregnancy decline in the late 2000s and early 2010s, with delaying sexual activity becoming the largest contributor in the subsequent decade.

Beyond sexual activity, violence rates have also fallen. Psychologists and writers suggest that as teenagers' lives have become longer, safer, and richer, they perceive the cost of taking risks to be higher, leading to a "slow life strategy." This is reflected in data showing a decline in good-risk behaviors as well; the share of high school seniors with a driver's license dropped from 82 percent in 2005 to 63 percent in 2023.

These trends began in the 1990s, predating widespread smartphone use and social media. Policy interventions have shown limited impact, with countries that spent heavily on teen pregnancy prevention seeing similar declines to those that spent nothing. One notable exception was MTV's "16 and Pregnant," which reportedly influenced behavior by realistically portraying the challenges of teen parenthood.

Broad Societal Shifts

The collapse in dangerous behaviors is widespread. Alcohol consumption among high school students dropped from 50 percent in 1991 to 22 percent in 2023. Cigarette use fell from 70 percent in 1991 to under 18 percent by 2021, with e-cigarette use also declining since 2019. Physical fights among high schoolers decreased from 42.5 percent in 1991 to 22 percent by 2019. A 2023 survey found that 66 percent of 12th graders abstained from alcohol, marijuana, or nicotine in the past month, a record high.

Surprisingly, even marijuana use among teens has fallen from its late-1990s peak, despite increased legalization for adults and greater perceived safety among young people. This caution is evident in reduced fatalities: the death rate for Americans aged 15-19 fell from 88 per 100,000 in 1990 to 45 per 100,000 by 2013. Safer vehicles, graduated driver licensing laws implemented since the mid-1990s, and a decrease in the number of teens obtaining licenses contributed significantly to this reduction in traffic fatalities.

The Cost of Caution

However, this broad reduction in risk-taking may have unintended consequences. The same caution that deters negative behaviors might also discourage positive risks, such as starting a business or pursuing unconventional paths. Falling rates of cultural and scientific risk-taking are noted alongside fewer physical altercations.

Furthermore, despite increased physical safety, adolescent mental well-being has declined. In 2023, 40 percent of high schoolers reported persistent sadness or hopelessness, a significant increase from 1999. Some experts suggest that while teens are safer in the physical world, they are less protected in online spaces that did not exist in the 1990s.

Despite these concerns about mental health, the overall shift in teenage behavior since the 1990s is a remarkable achievement. As writer Adam Mastroianni notes, society desired these improvements, and teenagers delivered them largely on their own, without widespread recognition or celebration.
