The given table provides information about the summary of weekly expenditure and the break down of salaries amongst school leavers and non-school leavers on five specific age cohorts over the course of a decade, commencing from 2000.
From an overarching view, there was an upward trend in both categories but the non-graduates class reached a peak first. In addition, the general earnings of graduates was higher than the other.
Delving into specifics, in terms of the initial graph, the total remuneration of alumni was £29.000, which was almost double the figure of non-alumni with only £17.800, resulting in a substantial gap of £12.100.
Looking at the detailed breakdown, it was apparent that diplomates aged 22 earned the lowest compared to the total, about £15.800, which was roughly half the figure of those aged over 30 years old. Meanwhile, 50-year-old graduates pulled in the largest number of money with £33.800. The 60 age cohort underwent a pronounced descent of £10.000, lasting only £23.100. Simultaneously, non-graduated at the identical age also witnessed a negligible descent of £3000. Those aged 32 to 42 years old earn money remain intact.
