The given graph illustrates the percentage of young children in different age groups in the United Kingdom from 1990 to 2001.
Overall, there is a huge difference in the percentages of each age group over time. While some groups experienced a huge drop, others showed an increase, with intersections occurring at certain points.
The 0-4 age group started at 26% in 1990 and gradually fell to 23.5% by 2001. In contrast, the 10-14 age group followed an opposite trend, beginning at 23.4% and rising to 26%. These two groups intersected in 1996, when they had approximately the same percentage.
The 5-9 age group started at 24.5%, while the 15-19 age group had the highest starting percentage of all, although both experienced variation. By 2001, these two groups connected at an approximate percentage of 25%.
In summary, the younger age groups (0-4 and 5-9) tended to minimize, whereas the older groups (10-14 and 15-19) showed an increase over the period, with significant intersections occurring throughout the years.
