Comprehensive crime statistics for Los Angeles County including homicides, property crime, robbery, assault, and neighborhood-by-neighborhood breakdowns with five-year trend analysis.

Serious violent crimes consist of Part 1 offenses as defined by the U.S. Department of Justice’s Uniform Reporting Statistics. These include murders, nonnegligent homicides, rapes (legacy and revised), robberies, and aggravated assaults. LAPD data were used for City of Los Angeles, LASD data were used for unincorporated areas and cities that contract with LASD for law enforcement services, and CA Attorney General data were used for all other cities with local police departments. This indicator is based on location of residence. Single-year data are only available for Los Angeles County overall, Service Planning Areas, Supervisorial Districts, City of Los Angeles overall, and City of Los Angeles Council Districts.Neighborhood violence and crime can have a harmful impact on all members of a community. Living in communities with high rates of violence and crime not only exposes residents to a greater personal risk of injury or death, but it can also render individuals more susceptible to many adverse health outcomes. People who are regularly exposed to violence and crime are more likely to suffer from chronic stress, depression, anxiety, and other mental health conditions. They are also less likely to be able to use their parks and neighborhoods for recreation and physical activity.For more information about the Community Health Profiles Data Initiative, please see the initiative homepage.

Comprehensive crime statistics for Los Angeles County's most dangerous neighborhoods including violent crime rates, property crime rates, gang activity, and annual victimization chances by neighborhood for 2024-2025.

There has been little research on United States homicide rates from a long-term perspective, primarily because there has been no consistent data series on a particular place preceding the Uniform Crime Reports (UCR), which began its first full year in 1931. To fill this research gap, this project created a data series that spans two centuries on homicides per capita for the city of Los Angeles. The goal was to create a site-specific, individual-based data series that could be used to examine major social shifts related to homicide, such as mass immigration, urban growth, war, demographic changes, and changes in laws. The basic approach to the data collection was to obtain the best possible estimate of annual counts and the most complete information on individual homicides. Data were derived from multiple sources, including Los Angeles court records, as well as annual reports of the coroner and daily newspapers. Part 1 (Annual Homicides and Related Data) variables include Los Angeles County annual counts of homicides, counts of female victims, method of killing such as drowning, suffocating, or strangling, and the homicide rate. Part 2 (Individual Homicide Data) variables include the date and place of the murder, the age, sex, race, and place of birth of the offender and victim, type of weapon used, and source of data.

In a world of increasing crime, many organizations are interested in examining incident details to learn from and prevent future crime. Our client, based in Los Angeles County, was interested in this exact thing. They asked us to examine the data to answer several questions; among them, what was the rate of increase or decrease in crime from 2020 to 2023, and which ethnicity or group of people were targeted the most.

Our data was collected from Kaggle.com at the following link:

FBI National Incident-Based Reporting System (FBI NIBRS) crime data for Los Angeles County, California, including incidents, statistics, demographics, and agency information.

This study used a mixed-methods approach to pursue five interrelated objectives: (1) to document the extent of case attrition and to identify the stages of the criminal justice process where attrition is most likely to occur; (2) to identify the case complexities and evidentiary factors that affect the likelihood of attrition in sexual assault cases; (3) to identify the predictors of case outcomes in sexual assault cases; (4) to provide a comprehensive analysis of the factors that lead police to unfound the charges in sexual assault cases; and (5) to identify the situations in which sexual assault cases are being cleared by exceptional means. Toward this end, three primary data sources were used: (1) quantitative data on the outcomes of sexual assaults reported to the Los Angeles Police Department (LAPD) and the Los Angeles County Sheriff's Department (LASD) from 2005 to 2009, (2) qualitative data from interviews with detectives and with deputy district attorneys with the Los Angeles District Attorney's Office who handled sexual assault cases during this time period, and (3) detailed quantitative and qualitative data from case files for a sample of cases reported to the two agencies in 2008.

The complete case files for sexual assaults that were reported to the Los Angeles Police Department and the Los Angeles County Sheriff's Department in 2008 were obtained by members of the research team and very detailed information (quantitative and qualitative data) was extracted from the files on each case in Dataset 1 (Case Outcomes and Characteristics: Reports from 2008). The case file included the crime report prepared by the patrol officer who responded to the crime and took the initial report from the complainant, all follow-up reports prepared by the detective to whom the case was assigned for investigation, and the detective's reasons for unfounding the report or for clearing the case by arrest or by exceptional means. The case files also included either verbatim accounts or summaries of statements made by the complainant, by witnesses (if any), and by the suspect (if the suspect was interviewed); a description of physical evidence recovered from the alleged crime scene, and the results of the physical exam (Sexual Assault Response Team (SART) exam) of the victim (if the victim reported the crime within 72 hours of the alleged assault). Members of the research team read through each case file and recorded data in an SPSS data file. There are 650 cases and 261 variables in the data file. The variables in the data file include administrative police information and charges listed on the police report. There is also information related to the victim, the suspect, and the case.

Datasets 2-5 were obtained from the district attorney's office and contain outcome data that resulted in the arrest of a suspect. The outcome data obtained from the agency was for the following sex crimes: rape, attempted rape, sexual penetration with a foreign object, oral copulation, sodomy, unlawful sex, and sexual battery.

Dataset 3 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Police Department - Adult Arrests) is a subset of Dataset 2 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Police Department - All Cases) in that it only contains cases that resulted in the arrest of at least one adult suspect. Dataset 2 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Police Department - All Cases) contains 10,832 cases and 29 variables. Dataset 3 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Police Department - Adult Arrests) contains 891 cases and 45 variables.

Similarly, Dataset 5 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Sheriff's Department - Adult Arrests) is a subset of Dataset 4 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Sheriff's Department - All Cases) in that it only contains cases that resulted in the arrest of at least one adult suspect. Dataset 4 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Sheriff's Department - All Cases) contains 3,309 cases and 33 variables. Dataset 5 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Sheriff's Department - Adult Arrests) contains 904 cases and 47 variables.

Data for cities, communities, and City of Los Angeles Council Districts were generated using a small area estimation method which combined the survey data with population benchmark data (2022 population estimates for Los Angeles County) and neighborhood characteristics data (e.g., U.S. Census Bureau, 2017-2021 American Community Survey 5-Year Estimates).Living in communities with high rates of violence and crime not only exposes residents to a greater personal risk of injury or death, but it can also render individuals more susceptible to many adverse health outcomes. People who are regularly exposed to violence and crime are more likely to suffer from chronic stress, depression, anxiety, and other mental health conditions. They are also less likely to be able to use their parks and neighborhoods for recreation and physical activity.For more information about the Community Health Profiles Data Initiative, please see the initiative homepage.

The purpose of this data collection was to investigate the effects of crime rates, city characteristics, and police departments' financial resources on felony case attrition rates in 28 cities located in Los Angeles County, California. Demographic data for this collection were obtained from the 1983 COUNTY AND CITY DATA BOOK. Arrest data were collected directly from the 1980 and 1981 CALIFORNIA OFFENDER BASED TRANSACTION STATISTICS (OBTS) data files maintained by the California Bureau of Criminal Statistics. City demographic variables include total population, minority population, population aged 65 years or older, number of female-headed families, number of index crimes, number of families below the poverty level, city expenditures, and police expenditures. City arrest data include information on number of arrests disposed and number of males, females, blacks, and whites arrested. Also included are data on the number of cases released by police, denied by prosecutors, and acquitted, and data on the number of convicted cases given prison terms.

This study was conducted in 1979 at the Social Science Research Institute, University of Southern California, and explores the relationship between neighborhood change and crime rates between the years 1950 and 1976. The data were aggregated by unique and consistently-defined spatial areas, referred to as dummy tracts or neighborhoods, within Los Angeles County. By combining United States Census data and administrative data from several state, county, and local agencies, the researchers were able to develop measures that tapped the changing structural and compositional aspects of each neighborhood and their interaction with the patterns of juvenile delinquency. Some of the variables included are annual income, home environment, number of crimes against persons, and number of property crimes.

organizations are becoming increasingly concerned with analyzing crime data to prevent future incidents and better understand the factors driving criminal behavior. One such organization, based in Los Angeles County, approached us with a request to conduct a comprehensive analysis of crime data in their area. They aimed to uncover key trends and insights that could inform strategies to enhance public safety and reduce the likelihood of future crimes.

The client's main focus was to assess how crime rates have evolved over time, particularly from 2020 to 2023, a period marked by numerous global and local challenges, including the COVID-19 pandemic and economic disruptions. They wanted to understand whether crime rates had increased, decreased, or remained stable during these years and what factors might have contributed to any observed changes. By examining the trends over this period, they hoped to identify patterns that could guide more effective crime prevention strategies in the future.

Another critical question the client posed was regarding the demographics of crime victims. Specifically, they sought to determine which ethnic groups or communities were most frequently targeted in criminal incidents. In an increasingly diverse city like Los Angeles, this information is essential for understanding whether certain populations are disproportionately affected by crime and, if so, why this might be the case. Identifying these patterns could allow for more targeted interventions to protect vulnerable communities and address underlying social or economic inequalities contributing to their higher victimization rates.

To address these questions, our analysis would involve a detailed examination of crime data from multiple sources, including law enforcement records and publicly available datasets. We would analyze the overall trends in crime rates over the specified time frame, breaking them down by type of crime, geographic location, and other relevant factors. Additionally, we would focus on victim demographics, including race, ethnicity, age, and gender, to determine if there were any noticeable disparities in victimization rates across different groups.

The results of this analysis would provide valuable insights not only for the client but also for policymakers, law enforcement agencies, and community organizations. By understanding the rate of increase or decrease in crime over recent years, we can gain a clearer picture of how crime is evolving and whether current measures are effective in curbing it. Furthermore, identifying which ethnic groups or populations are most affected by crime allows for a more equitable approach to crime prevention and public safety initiatives.

In conclusion, this analysis would serve as a crucial tool for the client and other stakeholders in Los Angeles County, helping them to make data-driven decisions that improve public safety and reduce the risk of future crimes. By focusing on both the overall trends and the specific demographics of crime victims, this comprehensive approach aims to address the root causes of crime and foster a safer, more inclusive community.

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.

By 1996 it became apparent that the Los Angeles county jails faced a serious overcrowding problem. Two possible solutions to the problem were to build more jail capacity or to divert a greater number of incoming inmates to community-based, intermediate sanctions. The research team for this study was asked to review a 1996 profile of inmates in the Los Angeles jail system and to determine how many of them might have been good candidates for intermediate sanctions such as electronic monitoring, work release, house arrest, and intensive supervision. The researchers selected a sample of 1,000 pre-adjudicated (or unconvicted) inmates from the total census of inmates in jail custody on January 15, 1996, to study in more detail. Of the 1,000 offenders, the researchers were able to obtain jail and recidivism data for two years for 931 inmates. For each of these offenders, information on their prior criminal history, current offense, and subsequent recidivism behavior was obtained from official records maintained by several county agencies, including pretrial services, sheriff's department, probation, and courts. Demographic variables include date of birth, race, and gender. Prior criminal history variables for each prior adult arrest include type of filing charge, case disposition, type of sentence and sentence length imposed, and total number of prior juvenile petitions sustained. Current offense variables include arrest date, crime type for current arrest, crime charge, type and date of final case disposition, and sentence type and length, if convicted. Strike information collected includes number of strikes and the offense that qualified as a strike. Jail custody variables include the jail entry and exit data for the current offense and the reason for release, if released. Lastly, two-year follow-up variables include the date, type, and disposition of each subsequent arrest between January 15, 1996, and January 15, 1998.

This data collection documents an evaluation of the Los Angeles County Sheriff's Regimented Inmate Diversion (RID) program conducted with male inmates who were participants in the program during September 1990-August 1991. The evaluation was designed to determine whether county-operated boot camp programs for male inmates were feasible and cost-effective. An evaluation design entailing both process and impact components was undertaken to fully assess the overall effects of the RID program on offenders and on the county jail system. The process component documented how the RID program actually operated in terms of its selection criteria, delivery of programs, length of participation, and program completion rates. Variables include demographic/criminal data (e.g., race, date of birth, arrest charge, bail and amount, sentence days, certificates acquired, marital status, employment status, income), historical state and county arrest data (e.g., date of crime, charge, disposition, probation time, jail time, type of crime), boot camp data (e.g., entry into and exit from boot camp, reason for exit, probation dates, living conditions, restitution order), drug history data (e.g., drug used, frequency, method), data on drug tests, and serious incidence data. The impact data were collected on measures of recidivism, program costs, institutional behavior, and RID's effect on jail crowding.

The objective of this study was to examine the observable offending patterns of recent and past drug offenders to assess the crime control potential associated with recent increases in the incarceration of drug offenders. The periods examined were 1986 (representing the second half of the 1980s, when dramatic shifts toward increasing incarceration of drug offenders first became evident), and 1990 (after escalating sentences were well under way). Convicted offenders were the focus, since these cases are most directly affected by changes in imprisonment policies, particularly provisions for mandatory prison terms. Offending patterns of convicted and imprisoned drug offenders were contrasted to patterns of convicted robbers and burglars, both in and out of prison. The researchers used data from the National Judicial Reporting Program (NJRP), sponsored by the U.S. Department of Justice, Bureau of Justice Statistics (BJS), for information on the court processing of individual felony convictions. The National Association of Criminal Justice Planners (NACJP), which maintains data for the approximately 50 counties included in the NJRP, was contracted to determine the counties to be sampled (Los Angeles County and Maricopa County in Arizona were chosen) and to provide individual criminal histories. Variables include number of arrests for robbery, violent crimes, property crimes, and other felonies, number of drug arrests, number of misdemeanor arrests, rate of violent, property, robbery, weapons, other felony, drug, and misdemeanor arrests, offense type (drug trafficking, drug possession, robbery, and burglary), total number of incarcerations, total number of convictions, whether sentenced to prison, jail, or probation, incarceration sentence in months, sex, race, and age at sampled conviction, and age at first arrest (starting at age 17).
