Some framework for the prisons debate

I thought that CoffeeHousers might appreciate a few graphs to steer them around the prisons debate. It’s by no means a complete overview of the issue, but just three of the trends that hover over Ken Clarke’s proposals:

1. Rising prison population, falling crime

Well, that’s striking enough. Expect, as any fule know, correlation doesn’t necessarily imply causation – which is to say, the fall in crime could be due to something other than the rise in prisoners. Some put it down to improving economic conditions. Others mention deterrents such as CCTV. But those correlations can barely be hardened into a cause, either. So, all rather inconclusive.

The Prison Works argument is strengthened, almost to the point of decisiveness, by the similar graphs that Civitas have produced for other countries. In many cases, falling crime is associated with rising prison populations, and vice versa.
