The divorce rate in the United States is abysmal. Every 13 seconds, someone in America gets divorced. Over a forty-year period, more than 67 percent of all marriages divorce. One-quarter of persons over the age of 18 had witnessed their parents' divorce. By comparison, only 10 percent of people worldwide have seen their parents divorced. Almost half of all children are born to unmarried mothers. Almost one in five babies are born to a mother under the age of 15. Teen pregnancy rates are high because young people lack the life experience and related social skills needed to make good decisions about their health and wellbeing. Teenagers marry younger today than they did ten years ago. Only 6% of teens now wait until after high school to marry, compared with 11% in 1991. The share of teenage marriages that end in divorce has fallen but so has everyone's marriage longevity. It used to be thought that married people lived longer than those who were not married. Now we know that this is not true for most people. Married people tend to die sooner than people who are not married. Young people are also having children later in life. The average age of women at first birth has increased from 20 to 24 over the past 50 years. For men, it's increased from 25 to 29. These days many young people focus on their education and career development instead of starting families right away.
