  • Summary

    The total fertility rate (TFR) is the average number of children a woman would have if she experienced the age-specific fertility rates for a particular year throughout her childbearing life. The peak ages for abortion are in the 20-24 and 16-19 year age groups. Conception statistics include both terminations of pregnancy by legal abortion and maternities in which one or more live births or stillbirths occur. Later generations had fewer children on average by their mid-20s, but higher rates in the future at older ages may mean their completed fertility rates are at a similar level to earlier cohorts. There has been a continued reduction in the age at which sexual intercourse first took place together with an increase in the proportion of young people who had sexual intercourse before the age of consent. In 2006/07, the youngest women were the least likely to be using contraception.
