The following line graph illustrates the weekly salaries in 2002 of full-time graduates, postgraduates, and individuals with various qualifications across different age ranges. A glance at the graph reveals that workers with other qualifications earned the most between their mid-30s and mid-40s, whereas postgraduates overtook all other groups in the oldest age range. First-degree holders consistently earned the least across all ages.
According to the data, while at the start of their careers (ages 21-25), they have the bottom income bracket, among categories, employees with other degree types have relatively the highest pay, reaching roughly £420. As the workers’ age grows, so do their salaries; still, those with distinct educational certifications earn the most at the ages of 36-40. However, by the 46, income drops gradually, with those having a first and higher degree reaching the same amount. Among 55-year-olds, trends changed, and postgraduates had the soaring revenue, nearly £790.
On the other hand, those having the first degree had modest earnings at all ages. For 40 years, the amount of salary was considerably growing, and after that, slight changes were visible, but mainly maintaining stability.
Overall, salaries tended to increase with age until reaching a peak in middle age, after which they generally declined.
