The Use of Incarceration in Canada: A Test of Political and Social Threat Explanations on the Variation in Prison Admissions across Canadian Provinces, 2001–2010

Recent scholarship has indicated that political and ethnic threat theories—which maintain that the use of prison is not only determined by the extent of crime in society but also by various features related to power, ideology, and access to resources—provide powerful accounts as to why the use of punishment varies within and between societies. However, no study to date has tested these theories within Canada, a country in which such theories are quite plausible. This study begins to fill this void by assessing these theoretical claims using a pooled time series analysis of the variation in imprisonment rates across Canadian provinces from the years 2001 to 2010. After accounting for several measures including charge rates, the results show that Canadian incarceration rates are largely driven by ethnic threat. The size of the Aboriginal and visible minority populations across each province are the most significant determinants of the variation in punishment. Furthermore, we find a nonlinear relationship consistent with a political version of the threat hypothesis. Results, however, do not support political accounts which stress the power of right‐wing parties or a conservative public.
