The graph illustrates the proportion of children in four different age groups (0-4, 5-9, 10-14, 15-19) in the United Kingdom between 1990 and 2001.
Overall, the percentage of children aged 10-14 is an upward trend, while the proportion of the 0-4 and 15-19 age groups declined; also, we can see that the 5-9 age group first rose and then fell down at the end.
In 1990, the percentage of children aged 0-4 was 26%, and then in 1992, it was close to 26.5%, followed by a massive decline at the end of the period to nearly 23.5% in 2001, although the percentage of children aged 5-9 first rose from 24.6% in 1990 to 25.2% in 2001.
On the other hand, in 1990, the proportion of children in the 10-14 age group was 23.2%, and this upward trend was maintained throughout the period, crossing 24% in 1996 and reaching 26.5% in 2001, while the last group of children, aged 15-19, was at 26.2% in 1990, and in the middle of the period, the percentage declined to 23%, while in 2001, it increased again and reached 25%.
In conclusion, although the youngest and oldest children saw a fall in their proportion during the period (0-4 and 15-19), the 10-14 age group increased. The 5-9 age group first declined and then rose.
