Idaho Statistical Analysis Center
The Idaho Statistical Analysis Center (ISAC) resides within the Planning, Grants and Research Department of the Idaho State Police. The overall purpose of ISAC, as established by the U.S. Bureau of Justice Statistics, is the systematic collection, analysis, and dissemination of statistics related to crime, illegal drugs, victim services, and the administration of justice. The purpose of our website is to provide criminal justice agencies and community organizations access to ISAC publications and other statistical information which can be used for development and analysis of policies, operations and programs.
ISAC Updates STOP Accomplishments Dashboard
April 12, 2022
Today ISAC updated its STOP Accomplishments dashboard to include data from Calendar Year 2021. Administered on the state level by the Planning, Grants & Research (PGR) Department of the Idaho State Police (ISP), the STOP (Services, Training, Officers, and Prosecutors) grant is a federal pass-through funding program authorized by Congress as part of the Violence Against Women Act (VAWA). STOP funds originate in the U.S. Department of Justice’s Office on Violence Against Women and are passed through to local agencies to support communities in their efforts to develop and strengthen effective criminal justice strategies to address domestic violence, sexual assault, stalking, and dating violence; and develop and enhance victim services in cases involving these crimes.
Some highlights from 2021:
- A total of 14 agencies across 9 counties and 5 ISP districts reported STOP-funded activities to PGR.
- STOP funding paid for over 32,600 hours of staff time, enabled 38 community-focused educational events, and funded 68 professional development trainings for 557 law enforcement officers, health care workers, court staff, victim advocates, and others.
- Agencies providing direct services to victims/survivors of sexual assault, domestic/dating violence, and stalking served 2,599 victims/survivors, 69% of which were victimized by a current or former intimate partner. The most commonly-used STOP-funded services were victim advocacy (provided to 67% of victims/survivors), crisis intervention (47%), and civil legal advocacy (28%).
- Law enforcement units funded by STOP conducted 104 investigations, leading to 15 arrests and 29 cases being referred for prosecution.
- Prosecution units funded by STOP received 111 cases, 67% of which were accepted for prosecution. Of those accepted for prosecution, 67% of cases resulted in a conviction or guilty plea.

ISAC Adds Property Crime Victimization to Crime in Idaho Data Dashboard
January 13, 2022
Today ISAC updated its Crime in Idaho data dashboard with data on property crime victimization. The new section displays data gathered from state and local law enforcement agencies around Idaho on crimes such as robbery, burglary, and motor vehicle theft, with a focus on victimization rate trends by county and victim demographics.
The Crime in Idaho data dashboard, which is still under construction, allows users to explore much of the data housed in the Idaho Incident-Based Reporting System, Idaho’s vast repository of law enforcement data on criminal incidents that occur within Idaho and the same data set that drives the annual Crime in Idaho report series. Agency, county, and state data from between 2005 and 2020 can be visualized in one place, allowing for highly customizable views and quick trend analysis. The dashboard currently contains sections pertaining to crimes against persons, crimes against property, and drug/alcohol-related arrests, with additional sections to follow as they are built. This project is a collaborative effort between ISAC and the Idaho Uniform Crime Reporting Program, both of which are components of the Idaho State Police.
ISAC Publishes Research Briefs on Sexual, Intimate Partner Violence
December 17, 2021
ISAC has published two research briefs examining recent trends in both sexual and intimate partner violence in Idaho.
Sexual Violence in Idaho, 2020 includes data victims known to law enforcement, victims who received grant-funded services, and feedback from victim service agencies. 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.
Intimate Partner Violence in Idaho, 2020 includes data on 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.
Both research briefs are available in the ISAC Publication Library.
ISAC Awarded Grant to Study Crime Patterns During COVID-19 Pandemic
October 26, 2021
ISAC has been awarded a research grant from the U.S. Bureau of Justice Statistics (BJS) to study crime patterns during the COVID-19 pandemic.
The award will fund a 1-year ISAC research project that will utilize data from the Idaho Incident-Based Reporting System as its foundation. ISAC plans to conduct an interrupted time-series analysis to compare crime trends before, during, and after the COVID-19 “stay-at-home” orders that were in effect in Idaho during March and April 2020. The analysis will also include county- and regional-level analyses to determine differential impacts to crime trends in different geographic areas. Finally, trends for incident types of particular interest to justice system stakeholders in Idaho, such as drug/alcohol crime, domestic violence, sexual violence, and violence against children, will be examined in-depth.
The grant was awarded under BJS’s State Justice Statistics (SJS) program, a competitive federal research grant aimed at enhancing states’ capacity to develop and carry out innovative and timely justice system research projects. Only state Statistical Analysis Centers are eligible for funding under the SJS program, positioning ISAC as the only entity in Idaho eligible for this funding. 2021 marks the fifth-straight year ISAC has earned an SJS award. Historically, the SJS program funds between 30 and 40 research proposals per year.
ISAC will publish results of the study in a technical report, which is currently slated for a Fall 2022 release.
ISAC Publishes Reports on Crossover Youth, Recidivism
October 12, 2021
ISAC is pleased to announce the release of two new research reports on the topics of crossover youth in Eastern Idaho and recidivism rates among Idaho’s felony offenders.
Crossover Youth in Eastern Idaho: Results from the District 6 Crossover Youth Practice Model Pilot Project presents the results of a pilot project in Bannock, Onedia, and Power Counties. Stakeholders from across the juvenile justice and child welfare systems came together in 2019 to begin implementing the Crossover Youth Practice Model (CYPM). Fully implemented in February 2020, the CYPM aims to streamline services for “crossover youth”, youth who are involved in both the juvenile justice and child welfare systems, by bringing together stakeholders from both systems to create joint case management plans that provide the most appropriate services to crossover youth in a more efficient manner. ISAC found that youth who “crossed over” after the CYPM was implemented experienced better outcomes on a wide range of measures as compared to youth who crossed over prior to CYPM implementation.
Recidivism Rates Among the Idaho Department of Correction’s Supervised Population presents results of a large recidivism study of felony offenders in Idaho. ISAC used data from the Idaho Department of Correction (IDOC) and the Idaho Supreme Court (ISC) to determine 3-year recidivism rates among felony offenders in Idaho, utilizing five definitions of recidivism. Using a series of survival analyses, ISAC determined actual and expected recidivism rates, as well as predictive demographic factors, for a group of more than 40,000 felony offenders that were under IDOC supervision between 2010 and 2017. Expected recidivism rates ranged from a low of 10% (technical probation/parole violations) to a high of 41% (charged with a new crime) three years after being released to the community from prison or being placed on probation, with slightly less than half of those recidivism events occurring within the first year. Across all recidivism types studied, being younger and male significantly increased the odds of an offender experiencing a recidivism event within their first three years in the community. The wide range in recidivism rates across the five definitions used in this study has implications for how recidivism should be studied in Idaho in the future, which ISAC also outlines in the report.
