TL;DR
This study examines prison homicides and suicides in Chile from 2000 to 2024, identifying regional trends and risk factors.
Contribution
The study provides new insights into the ecological factors and temporal trends of prison homicides and suicides in Chile.
Findings
Southern regions had the highest incidence rates of external causes of death in prisons.
National homicide rates decreased, but some southern regions saw increases.
Suicide rates remained stable, with higher risks in regions with more violent offenders.
Abstract
External (non-natural) causes of death are frequent in prison. This study aimed to assess the incidence, associated ecological factors, and changes over time of prison homicides and suicides in Chile between 2000 and 2024. National and regional cases of homicides and suicides in prison were obtained by year through Transparency Council requests to the Chilean prison authority. Corresponding incidence data in the general population were retrieved from publicly available sources. Incidence rates were estimated per 100,000 person-years of imprisonment and compared between regions. The proportion of external causes of death among overall mortality in prison was also calculated. Prais-Winsten autoregressive models were used to analyze changes in incidence over time. Latent structures underlying the incidence were explored using principal component analysis (PCA). Incidence rates of…
