The provided pie charts present information about the distribution of British visitors to Spain by age groups in the years 1983 and 2003. Throughout the two decades, the proportions of visitors show noticeable changes overall. While the 34-54 age group remained the dominant category in both years, its numbers faced a significant decline by 2003; older (55+) and younger (0-15 and 16-24 years) travelers experienced an upward trend, albeit more moderately. In contrast, the notable decrease of the 25-34 age group mirrors that of the largest group.
Regarding groups with a downward trend, the 34-54 age group made up 50% of all visitors in 1983, yet the numbers dropped to 35% by 2003. Despite the major decline, it stayed the largest segment of both years. The 25-34 age group also saw a significant decrease, which fell to 12% in 2003, with its previous count being 20% in 1983. This indicates fewer visitors of these two age groups traveled to Spain over time.
On the contrary, the proportion of visitors aged 55 and over grew considerably after two decades, rising from 16% to 26%, whereas the 0-15 figure saw a marginal rise by 2% (10% to 12%). Following the upward trend, the 16-24 category quadrupled to 15% in 2003, its previous count taking over only 4% of all travelers in 1983.
