Recent Trends – Population aged 11 to 19 years

IBISWorld expects the number of people aged from 11 to 19 to increase at a compound annual rate of 1.6% to total 7.2 million over the five years through 2022-23. The number of people aged from 11 to 19 increased steadily throughout the period in line with the number of births rising in the early 2000s. The number of rising births reversed the declining trend in this age group's demographics from 2015-16 and is expected to continue to grow through to the current year. In 2022-23, the number of people aged 11 to 19 is set to increase by 2.3%, as the full effect of the rising birth rate pushes growth in this age group.

The number of births picked up over 2002-03 and continued to grow for the next decade. The number of people entering the age cohort is finally beginning to outweigh those leaving, supporting growth. A rise in the birth rate prior to the recessionary period was due to financial stability, supportive child benefits and medical advances encouraging more women to have babies later in their life. The vastly higher levels of net migration also supported growth in the age cohort, with immigrants more likely to be of childbearing age as well as bringing their own children with them.
