Samenvatting

This article studies the development in the prison system over the period 1837-2016 in the Netherlands. It describes trends in three characteristics of the Dutch prison system: (a) the number of prisoners, (b) the number of cells, and (c) the inflow of persons from the free society. The findings are twofold. On the one hand – when examining absolute numbers – the article shows that three distinct periods can be distinguished: a period of 140 years with low stable numbers (1837-1975), four decades in which the numbers tripled (1975-2005), and a subsequent decade where the numbers halved (2005-2016). On the other hand – when examining relative numbers, i.e. per 100.000 inhabitants, and thus controlling for the growth in population – the article displays that developments in the prison system in the Netherlands between 1837-2016 can best be characterized by a long-term continuous decrease in detention.
