The supplied tables demonstrate the salaries of graduates and non-graduates in Great Britain from 2000 to 2010.
Generally, it becomes apparent that the income of graduates remarkably surpassed the non-graduates and their average salaries experienced an ascending trajectory until the age of 52. Comparatively, the average earnings of non-graduates oscillated during the surveyed age with the highest occurring at the age of 32 and 42.
In terms of all age groups, it is notable that graduates received an average of 29900 pounds, while non-graduates earned at a much lower rate with 17800 pounds.
Shifting focus to particular ages, it is evident that there was little discrepancy at the average earning at the age of 22 with around 1500 pounds for all types. Nonetheless, the average income of graduates had risen consistently to the pinnacle of 33900 pounds at the age of 52 before reducing dramatically to 23100 pounds ultimately. Additionally, the average salaries of non-graduates peaked at 19100 pounds in 32 and 42 years old; however, it had descended consistently to 18200 pounds and 15300 pounds, consecutively.
