Racing round the Brands Hatch graph

Michael Blastland’s series on interpreting numbers on the BBC website is always worth following, but today’s entry on education spending is particularly interesting.   And not just because he had to enlist the help of a House of Commons librarian to get to the root of the figures.

The Brands Hatch graph takes a little while to take in, but is a very effective way of showing the relationship between three different factors: pupil numbers, date, and spending.  And it’s interesting to see the timing of the rise and fall in pupil numbers, with the rapid fall starting in 1982 by which time the last of the baby boomers had left school.
