description: This data includes annual data on murder and non-negligent manslaughter, violent crime rates per 100,000 population, and property crime rates per 100,000 for New Orleans and the bench mark cities of Atlanta, Nashville, Oklahoma City, Tampa, Miami, Memphis, Raleigh, and Baton Rouge.; abstract: This data includes annual data on murder and non-negligent manslaughter, violent crime rates per 100,000 population, and property crime rates per 100,000 for New Orleans and the bench mark cities of Atlanta, Nashville, Oklahoma City, Tampa, Miami, Memphis, Raleigh, and Baton Rouge.

Does the rate of violent victimization differ across race and ethnic groups? In an effort to answer this question, this study sought to examine the violent victimization rate and the factors influencing ethnic-specific rates of violence in the city of Miami. Administrative data were obtained from the United States Bureau of the Census and the Miami Police Department Research Unit. For the groups of people identified as Afro Americans, Latinos, and Haitians, the numbers who were victims of aggravated assault and robbery in 1997 are included along with the assault and robbery rates for each group. The remaining variables are the percent of female-headed households, percent below poverty line, percent of young males out of the labor force and unemployed, residential instability, vacant and household instability, and the percent of 1980-1990 immigrants.

The purpose of this data collection was to measure the validity or accuracy of four recidivism prediction instruments: the INSLAW, RAND, SFS81, and CGR scales. These scales estimate the probability that criminals will commit subsequent crimes quickly, that individuals will commit crime frequently, that inmates who are eligible for release on parole will commit subsequent crimes, and that defendants awaiting trial will commit crimes while on pretrial arrest or detention. The investigators used longitudinal data from five existing independent studies to assess the validity of the four predictive measures in question. The first data file was originally collected by the Vera Institute of Justice in New York City and was derived from an experimental evaluation of a jobs training program called the Alternative Youth Employment Strategies Project implemented in Albuquerque, New Mexico, Miami, Florida, and New York City, New York. The second file contains data from a RAND Corporation study, EFFECTS OF PRISON VERSUS PROBATION IN CALIFORNIA, 1980-1982 (ICPSR 8700), from offenders in Alameda and Los Angeles counties, California. Parts 3 through 5 pertain to serious juvenile offenders who were incarcerated during the 1960s and 1970s in three institutions of the California Youth Authority. A portion of the original data for these parts was taken from EARLY IDENTIFICATION OF THE CHRONIC OFFENDER, 1978-1980: CALIFORNIA. All files present demographic and socioeconomic variables such as birth information, race and ethnicity, education background, work and military experience, and criminal history, including involvement in criminal activities, drug addiction, and incarceration episodes. From the variables in each data file, standard variables across all data files were constructed. Constructed variables included those on background (such as drug use, arrest, conviction, employment, and education history), which were used to construct the four predictive scales, and follow-up variables concerning arrest and incarceration history. Scores on the four predictive scales were estimated.

California reported the largest number of homicides to the FBI in 2023, at 1,929 for the year. Texas recorded the second-highest number of murders, with 1,845 for the year. Homicide victim demographics There were a total of 19,252 reported homicide cases in the U.S. in 2023. When looking at murder victims by gender and ethnicity, the vast majority were male, while just over half of the victims were Black or African American. In addition, homicide victims in the United States were found most likely to be between the ages of 20 and 34 years old, with the majority of victims aged between 17 to 54 years old. Are murders up? In short, no – since the 1990s the number of murders in the U.S. has decreased significantly. In 1990, the murder rate per 100,000 people stood at 9.4, and stood at 5.7 in 2023. It should be noted though that the number of homicides increased slightly from 2014 to 2017, although figures declined again in 2018 and 2019, before ticking up once more in 2020 and 2021. Despite this decline, when viewed in international comparison, the U.S. murder rate is still notably high. For example, the Canadian homicide rate stood at 1.94 in 2023, while the homicide rate in England and Wales was even lower.
