Scottish Prison Population Projections: June 2024 Edition

This report presents short-term Scottish prison population projections for the six month period from May to October 2024. They have been produced using ‘microsimulation’ scenario modelling which simulates prison arrivals and departures, and estimates the number of individuals in prison.


Footnotes

1. The projections start at the beginning of May because data available to us on cases progressing through courts only currently extends up to the end of April 2024 (due to a time lag on receiving the processed data). As a result, the initial prison population used for the modelling is taken from 1st May 2024.
