Offending Patterns among Domestic Violence Offenders in Idaho
August 2022

This report presents results from a study of the criminal history records (CHR) of more than 56,000 individuals who have been arrested for a domestic violence (DV) crime in Idaho over the last 35 years. Demographics, criminal histories, and recidivism of DV offenders are all examined here. Additionally, ISAC evaluated the utility of using CHR data for research purposes. The implications of the study findings for public policy are also discussed.

Results indicate that the average DV offender in Idaho was male and in his mid-30s at the time of his first DV arrest. Nearly half of DV offenders (48%) had been previously arrested for a violent, property, or drug crime before their first DV arrest. About 45% of DV cases for which data was available resulted in a conviction for a DV crime. Finally, 40% of DV offenders were rearrested for a new misdemeanor or felony within five years of their first DV arrest, with 17% being arrested on new DV charges. Offender gender, age, and criminal history were significant predictors of recidivism.


Crime Victimization in Idaho: An Overview of Available Data
August 2022

This report and its companion data dashboard were developed in partnership with the Department of Criminal Justice at Boise State University (BSU) for their Idaho Victimization Clearinghouse website. BSU and ISAC sought to report on the status of victimization data in the state, as well as examine data regarding risk and protective factors that may impact victimization. The report includes an overview of existing data on victimization in Idaho, examines strengths and weaknesses of the data, and makes recommendations for improving the state’s knowledge of crime victimization.


Intimate Partner Violence in Idaho, 2020
December 2021

This research brief examines recent trends regarding intimate partner violence in Idaho. Data includes victims known to law enforcement, victims who received grant-funded services, and feedback from victim service agencies. Since 2016, the rate of victims known to law enforcement per capita has decreased, but the number of victims accessing grant-funded services has increased. Notable agency needs include resources to train and retain staff, expand service availability, respond to evolving effects of the COVID-19 pandemic, and provide safe shelter or housing to victims of intimate partner violence.


Sexual Violence in Idaho, 2020

This research brief examines recent trends regarding sexual violence in Idaho.

Since 2016, both the rate of victims known to law enforcement per capita and the number of victims accessing grant-funded services has increased. Notable agency needs include resources to train and retain staff, respond to evolving effects of the COVID-19 pandemic, and provide safe shelter or housing to victims of sexual violence.
