The given table compares the percentage of different age groups of UK visitors to Spain between 1981 and 2015.
Overall, it can be clearly seen that the proportion of people aged between 25 and 45 dropped significantly, while young and elderly individuals experienced the opposite pattern.
Looking at the details, people aged 25-35, at the outset of the period, accounted for a significant share of UK visitors to Spain (50%), and those aged 36-45, who ranked second, stood at 22%. Nevertheless, both underwent substantial declines in 2015, going down to 32% and 12%, respectively.
In contrast, although young people recorded the lowest ratio (4%) at the beginning, which was four times as low as that of elderly people (16), their percentage almost quadrupled at the end of the time span (15%). Similarly, there was also a noticeable growth in the figure for children, rising from 10% in 1981 to 12% in 2015.
