Walkforward Research Paper 2026/02. Version 1.0, September 2026. Eighteen editions of the Ministry of Justice prison population projections since 2008, with every central projection scored against what happened at every horizon. The projections have been too high at every horizon, and a forecaster who assumed no change would have beaten them on identical targets. Code at github.com/walkforwardresearch/prisoncap.
