The rate of teenage pregnancy among under 18s in Cardiff is higher than the Wales average, and the UK has among the highest rates of teenage pregnancy in the European Union. However, Cardiff has followed the UK trend and seen significant decreases in recent years; the UK rate has halved since 1998.

Teenage pregnancy can often be linked to other indicators of disadvantage and an increased level of females not in education, employment or training. It is also linked to lower birth weights, poor antenatal health and poor maternal mental health. Rates of teenage pregnancy tend to be higher in more deprived areas. The challenges involved in parenting at a young age can have long-term effects on not just that generation but on the prospects of future ones as well.
