Drug Offending in Cleveland, Ohio Neighborhoods, 1990-1997 and 1999-2001 (ICPSR 3929)

Released/updated on: 2004-06-17

Geographic coverage: United States, Ohio, Cleveland

This study investigated changes in the geographic concentration of drug crimes in Cleveland from 1990 to 2001. The study looked at both the locations of drug incidents and where drug offenders lived in order to explore factors that bring residents from one neighborhood into other neighborhoods to engage in drug-related activities. This study was based on data collected for the 224 census tracts in Cleveland, Ohio, in the 1990 decennial Census for the years 1990 to 1997 and 1999 to 2001. Data on drug crimes for 1990 to 1997 and 1999 to 2001 were obtained from Cleveland Police Department (CPD) arrest records and used to produce counts of the number of drug offenses that occurred in each tract in each year and the number of arrestees for drug offenses who lived in each tract. Other variables include counts and rates of other crimes committed in each census tract in each year, the social characteristics and housing conditions of each census tract, and net migration for each census tract.

Examining the Multifaceted Impacts of Drug Decriminalization on Public Safety, Law Enforcement, and Prosecutorial Discretion, Oregon, 2008-2024 (ICPSR 39669)

Released/updated on: 2026-03-11

Geographic coverage: Oregon, United States

Time period: 2008-01-01--2024-01-01

This project sought to understand the effects of successive drug policy reforms in the state of Oregon. These include three changes since 2013 to reduce the enforcement and punishment of low-level drug possession. House Bill 3194 passed in 2013, which reduced mandatory minimum sentences for marijuana offenses and diverted more driving and drug-related offenses to probation. House Bill 2355 passed in 2017, which reclassified Schedule I and II possession of controlled substance (PCS), reducing these from a moderate felony to a misdemeanor. Then in 2021, M110 was implemented, downgrading certain quantities of PCS from a misdemeanor to a citation, resulting in a maximum 100 dollar fine or completed health assessment.

The researchers conducted a retrospective longitudinal analysis using statewide administrative data to assess the impacts of these drug law reforms. Measures included police stops, PCS arrests, court filings, convictions, jail and prison admissions, crime rates, drug seizures, and drug-related overdose deaths.

Oklahoma Methamphetamine Data Initiative, 2018-2022 (ICPSR 38656)

Released/updated on: 2023-12-14

Geographic coverage: United States, Oklahoma

Time period: 2010-01-01--2019-12-31

The Oklahoma Methamphetamine Data Initiative (OMDI) sought to examine the relationship between methamphetamine and violent crime. Both national and local drugs and crime data were collected to inform narcotics law enforcement intervention strategies. OMDI's goals are to establish procedures and metrics to evaluate the relationship between meth and violent crime; identify static and dynamic factors associated with violent crime stemming from meth use or distribution to improve community surveillance in Oklahoma; develop a regularly updated dashboard for law enforcement prevention/intervention deployment; and demonstrate the utility of this model for other states, rural areas, and Indian Country.

Operation Hardcore [Crime] Evaluation: Los Angeles, 1976-1980 (ICPSR 9038)

Released/updated on: 2006-01-12

Geographic coverage: United States, Los Angeles, California

Time period: 1976-01-01--1980-01-01

This evaluation was developed and implemented by the Los Angeles District Attorney's Office to examine the effectiveness of specialized prosecutorial activities in dealing with the local problem of rising gang violence, in particular the special gang prosecution unit Operation Hardcore. One part of the evaluation was a system performance analysis. The purposes of this system performance analysis were (1) to describe the problems of gang violence in Los Angeles and the ways that incidents of gang violence were handled by the Los Angeles criminal justice system, and (2) to document the activities of Operation Hardcore and its effect on the criminal justice system's handling of the cases prosecuted by that unit. Computer-generated listings from the Los Angeles District Attorney's Office of all individuals referred for prosecution by local police agencies were used to identify those individuals who were subsequently prosecuted by the District Attorney. Data from working files on all cases prosecuted, including copies of police, court, and criminal history records as well as information on case prosecution, were used to describe criminal justice handling. Information from several supplementary sources was also included, such as the automated Prosecutors Management Information System (PROMIS) maintained by the District Attorney's Office, and court records from the Superior Court of California in Los Angeles County, the local felony court.
