The provided line chart depicts the proportion of four different age brackets of the young generation in the UK over the period of 1990 to 2001.
Overall, it is observed that the data of infants and pre-kindergatens shared a strikingly contrary pattern to that of teenagers aged 10 to 14, in which the former underwent a sharp fall and the latter steadily increased. Additionally, a dramatic decrease was witnessed in the rate of 5-to-9-year-old before a recovery, in contrast to adolescene aged 15 to 19, which gradually increased.
First and foremost, the majority of UK youngsters were under the age of zero to four in the first five years of the period, accounting for around 26%. However, this figure sharply descended by nearly 3% in the following six years, whereas the 10 – 14 age cohort consistently surged from about 23% to its peak at more than 26% at the end of the period, after overtaking the data of children under four years of age in 1997.
Furthermore, a rapid growth to approximately 26% was observed in the rate of children aged five to nine in 1997 prior to a marginal decrease by 1% four years later. A noticeable opposite pattern could be seen in the trend of adolescence aged 15 to 19. Although the percentage of youngsters under the age of 15 to 19 was approximately 2% more than those aging five to nine in 1990, this data sharply plummeted to about 23% in 1994, prior to a reupsurgence to precisely 25% in the final year.
