The line graph shows the number of unemployed recent graduates and non-graduates in the population of 21 to 30-year-olds in the years between 1990 and 2015. Overall, the numbers have not changed much: we can see a fall, followed by a rise, in both groups. The non-graduates are a larger number than the recent graduates at all points.
Between 1990 and 2000 there was a decrease in the number of unemployed recent graduates and non-graduates. The fall was small from 1990 to 1995, but greater between 1995 and 2000.
There was a small change in the middle period. The number of non-graduates dropped and then grew during that period. Over the five years from 2010 to 2015, the numbers of both non-graduates and  recent graduates returned almost to their 1990 figures of 14% and 10%.
Overall, it is clear that having a degree is helpful in finding employment as more non-graduates than recent graduates are out of work.
