* Survey indicates 4% of participants experienced vaginal intercourse at the age 10 or less.
** The study indicates the "pregnancy rate" is 8.6 per 1,000 girls under the age of 15, or 0.86 out of 100. There were an estimated 17,340 pregnancies amongst a population of 2 million girls under the age of 15. CDC data for girls age 10 to 14 indicates a "birth rate" of 0.6 per 1,000 girls, or 0.06 per 100. CDC reports 6,396 births for mothers under the age of 15, in 2006.

Table 6

For One Year of Use

The following table provides estimates of the percent of women likely to become pregnant while using a particular contraceptive method for one year. These estimates are based on a variety of studies.

"Typical Use" rates mean that the method either was not always used correctly or was not used with every act of sexual intercourse (e.g., sometimes forgot to take a birth control pill as directed and became pregnant), or was used correctly but failed anyway.

"Lowest Expected" rates mean that the method was always used correctly with every act of sexual intercourse but failed anyway (e.g., always took a birth control pill as directed but still became pregnant).
