Many Western countries have instituted sex education programs, the main objective of which is to reduce unplanned pregnancies and STDs. The teenage birth rate in the United States is the highest in the developed world, and the teenage abortion rate is also high. For instance, long-term studies by Duke University economist V.

The Utah Department of Human Services found that girls who had left the foster care system between 1999 and 2004 had a birth rate nearly 3 times the rate for girls in the general population.  In well-nourished females, menarche usually takes place around the age of 12 or 13. Most knew little about housing or financial aid before they got pregnant and what they thought they knew often turned out to be wrong. Moreover, 51% of the girls reported experiencing at least one instance where their boyfriend attempted to sabotage their efforts to use birth control.  For girls aged 15â19 risks are associated more with socioeconomic factors than with the biological effects of age.
