0.3 Teenage births

Teenage motherhood is associated with poorer health and wellbeing outcomes for both the mother and her children. Teenage mothers face increased risk of physical and psychological difficulties while having their children. They are also more likely to be socioeconomically disadvantaged and to have lower levels of education, and are less likely to attend antenatal classes, than older mothers.

For all indicator displays, where all years of data are comparable over time an ‘All’ category will be provided as an option in the ‘Year’ drop down display. If only a selection of specific years are comparable, these years (e.g. 2017 to 2019) will be provided as an option under ‘Year’ and ‘All’ will not be an option. See the footnotes for this indicator in the supplementary tables hyperlink below for further information.

Explanatory notes

The indicator numerator reflects the number of births, not the number of mothers. Some mothers may have had multiple births during the reference period.

Mother’s age is at the time of birth. Due to the small number of births occurring among women aged less than 15 years, births to mothers aged under 15 years are included in the numerator but not the denominator.

The teenage birth rate is distinct from the teenage pregnancy rate. The birth rate includes only live births and is therefore lower than the pregnancy rate, which would include stillbirths, miscarriages and terminations.
