In 2022, the New Orleans-Metairie, LA metro area recorded the highest homicide rate of U.S. cities with a population over 250,000, at 27.1 homicides per 100,000 residents, followed by the Memphis, TN-MS-AR metro area. However, homicide data was not recorded in all U.S. metro areas, meaning that there may be some cities with a higher homicide rate.

St. Louis

St. Louis, which had a murder and nonnegligent manslaughter rate of 11.6 in 2022, is the second-largest city by population in Missouri. It is home to many famous treasures such as the St. Louis Cardinals baseball team, Washington University in St. Louis, the Saint Louis Zoo, and the renowned Gateway Arch.

Crime in St. Louis

Despite all of this, St. Louis suffers from high levels of crime and violence. As of 2023, it was listed as the seventh most dangerous city in the world as a result of their extremely high murder rate. Not only does St. Louis have one of the highest homicide rates in the United States, it also reports one of the highest numbers of violent crimes. In spite of high crime levels, the GDP of the St. Louis metropolitan area has been increasing since 2001.

V8 release notes: Adds 2017 data.V7 release notes: Removes SPSS (.sav) and Excel (.csv) files. Changes column names for clearances to "tot_clr_..." to make explicit that this is all clearances, not just adult clearances. The formatting of the monthly data has changed from wide to long. This means that each agency-month has a single row. The old data had each agency being a single row with each month-crime (e.g. jan_act_murder) being a column. Now there will just be a single column for each crime (e.g. act_murder) and the month can be identified in the month column. Adds a month column and a date column. This date column is always set to the first of the month. It is NOT the date that a crime occurred or was reported. It is only there to make it easier to create time-series graphs that require a date input. Removes all card columns. This was done to reduce file size. Reorders crime columns to the order of assaults/deaths of officers, actual crimes, total clearance, clearance under age 18, unfounded. Within each category the columns are alphabetized.Monthly data and yearly data are now in different zip folders to download.V6 release notes: Fix bug where Philadelphia Police Department had incorrect FIPS county code. V5 release notes: Changes the word "larceny" to "theft" in column names - eg. from "act_larceny" to "act_theft."Fixes bug where state abbrebation was NA for Washington D.C., Puerto Rico, Guam, and the Canal Zone.Fixes bug where officers_killed_by_accident was not appearing in yearly data. Note that 1979 does not have any officers killed (by felony or accident) or officers assaulted data.Adds aggravated assault columns to the monthly data. Aggravated assault is the sum of all assaults other than simple assault (assaults using gun, knife, hand/feet, and other weapon). Note that summing all crime columns to get a total crime count will double count aggravated assault as it is already the sum of existing columns. Reorder columns to put all month descriptors (e.g. "jan_month_included", "jan_card_1_type") before any crime data.Due to extremely irregular data in the unfounded columns for New Orleans (ORI = LANPD00) for years 2014-2016, I have change all unfounded column data for New Orleans for these years to NA. As an example, New Orleans reported about 45,000 unfounded total burglaries in 2016 (the 3rd highest they ever reported). This is 18 times largest than the number of actual total burglaries they reported that year (2,561) and nearly 8 times larger than the next largest reported unfounded total burglaries in any agency or year. Prior to 2014 there were no more than 10 unfounded total burglaries reported in New Orleans in any year. There were 10 obvious data entry errors in officers killed by felony/accident that I changed to NA.In 1974 the agency "Boston" (ORI = MA01301) reported 23 officers killed by accident during November.In 1978 the agency "Pittsburgh" (ORI = PAPPD00) reported 576 officers killed by accident during March.In 1978 the agency "Bronx Transit Authority" (ORI = NY06240) reported 56 officers killed by accident during April.In 1978 the agency "Bronx Transit Authority" (ORI = NY06240) reported 56 officers killed by accident during June.In 1978 the agency "Bronx Transit Authority" (ORI = NY06240) reported 56 officers killed by felony during April.In 1978 the agency "Bronx Transit Authority" (ORI = NY06240) reported 56 officers killed by felony during June.In 1978 the agency "Queens Transit Authority" (ORI = NY04040) reported 56 officers killed by accident during May.In 1978 the agency "Queens Transit Authority" (ORI = NY04040) reported 56 officers killed by felony during May.In 1996 the agency "Ruston" in Louisiana (ORI = LA03102) reported 30 officers killed by felony during September.In 1997 the agency "Washington University" in Missouri (ORI = MO0950E) reported 26 officers killed by felony during March.V4 release notes: Merges data with LEAIC data to add FIPS codes, census codes, agency type variables, and ORI9 variable.Makes all column names lowercase.Change some variable namesMakes values in character columns lowercase.Adds months_reported variable to yearly data.Combines monthly and yearly files into a single zip file (per data type).V3 release notes: fixes a bug in Version 2 where 1993 data did not properly deal with missing values, leading to enormous counts of crime being report

Summary: This is a collection of Offenses Known and Clearances By Arrest data from 1960 to 2016. Each zip file contains monthly and yearly data files. The monthly files contain one data file per year (57 total, 1960-2016) as well as a codebook for each year. These files have been read into R using the ASCII and setup files from ICPSR (or from the FBI for 2016 data) using the package asciiSetupReader. The end of the zip folder's name says what data type (R, SPSS, SAS, Microsoft Excel CSV, Stata) the data is in. The files are lightly cleaned. What this means specifically is that column names and value labels are standardized. In the original data column names were different between years (e.g. the December burglaries cleared column is "DEC_TOT_CLR_BRGLRY_TOT" in 1975 and "DEC_TOT_CLR_BURG_TOTAL" in 1977). The data here have standardized columns so you can compare between years and combine years together. The same thing is done for values inside of columns. For example, the state column gave state names in some years, abbreviations in others. For the code uses to clean and read the data, please see my GitHub file h

The International Association of Chiefs of Police (IACP), collaborating with research partners, conducted a 48-month, two-phase research initiative to enhance their understanding of how firearms move from legal purchase to involvement with a crime. Phase 1 used trace data from Chicago, New Orleans, and Prince Georges County, MD to establish the path of firearms from purchase to usage in a crime. Interviews of the first legal purchaser and incarcerated inmates who committed a crime of violence in New Orleans and Prince Georges County were conducted to seek an understanding of how firearms enter the unregulated market. Phase 2 examined the use of the Group Violence Reduction Strategy (GVRS) in New Orleans as a strategy to reduce gang and gun-related homicides. Overall violence patterns in New Orleans were examined from 2010-2016.

The Drug Market Intervention (DMI) has been identified as a promising practice for disrupting overt-drug markets, reducing the crime and disorder associated with drug sales, and improving police-community relations. Montgomery County, Maryland; Flint, Michigan; Guntersville, Alabama; Lake County, Indiana; Jacksonville, Florida; New Orleans, Louisiana; and Roanoke, Virginia applied for and received DMI training and technical assistance from Michigan State University in 2010 and 2011. This study followed the seven sites that were trained in the program to determine how the program was implemented, how the DMI affected the targeted drug market, whether the program affected crime and disorder, whether the program improved police-community relations, and how much the program cost.

The Prosecutor's Management and Information System (PROMIS) is a computer-based management information system for public prosecution agencies. PROMIS was initially developed with funds from the United States Law Enforcement Assistance Administration (LEAA) to cope with the problems of a large, urban prosecution agency where mass production operations had superseded the traditional practice of a single attorney preparing and prosecuting a given case from inception to final disposition. The combination of massive volumes of cases and the assembly-line fragmentation of responsibility and control had created a situation in which one case was indistinguishable from another and the effects of problems at various stages in the assembly line on ultimate case disposition went undetected and uncorrected. One unique feature of PROMIS that addresses these problems is the automated evaluation of cases. Through the application of a uniform set of criteria, PROMIS assigns two numerical ratings to each case: one signifying the gravity of the crime through a measurement of the amount of harm done to society, and the other signifying the gravity of the prior criminal record of the accused. These ratings make it possible to select the more important cases for intensive, pre-trial preparation and to assure even-handed treatment of cases of like gravity. A complementary feature of PROMIS is the automation of reasons for decisions made or actions taken along the assembly line. Reasons for dismissing cases prior to trial on their merits can be related to earlier cycles of postponements for various reasons and to the reasoning behind intake and screening decisions. The PROMIS data include information about the defendant, case characteristics and processes, charge, sentencing and continuance processes, and the witnesses/victims involved with a case. PROMIS was first used in 1971 in the United States Attorney's Office for the District of Columbia. To enhance the ability to transfer the PROMIS concepts and software to other communities, LEAA awarded a grant to the Institute for Law and Social Research (INSLAW) in Washington, DC. The New Orleans PROMIS data collection is a product of this grant.
