Scottish Prison Population Projections: February 2024 Edition

This report presents short-term Scottish prison population projections for the six month period from January to June 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 January because data available to us on cases progressing through courts only currently extends up to the end of December 2023 (due to a time lag on receiving the processed data). As a result, the initial prison population used for the modelling is from 1st January 2024.

22 Seasonal trends for the prison population since the pandemic feature some general similarities around the turn of the year. The sentenced population around late November/early December tends to increase and then between Christmas and the first week of January decrease steeply. The remand population tends to reduce from late November/early December, tends to increase sharply and then stabilise between Christmas and the New Year. The total population tends to fall slightly in late November/early December, then falls more sharply in late December before recovering somewhat by early February.
