Variation in post-graduate earnings

If you (and your parents!) are going to spend a lot of money on a university education, it's useful to know what you can expect to earn on completing it and it seems that there's variation from one university to another. Later this year, the DfE will publish "longitudinal analysis" of graduate earnings, based on government tax records but some preliminary data is published below.  It shows the earnings of Law graduates, five years after graduating, with the numbers of students at each institution:
