In 2019, there were six deaths by homicide per 100,000 of the population in the United States, compared to 5.9 deaths by homicide in the previous year. This is an increase from 1950, when there were 5.1 deaths by homicide per 100,000 resident population in the United States. However, within the provided time period, the death rate for homicide in the U.S. was highest in 1980, when there were 10.4 deaths by homicide per 100,000 of the population in the United States.

Homicides in the United States

The term homicide is used when a human being is killed by another human being. Criminal homicide takes several forms, for example murder; but homicide is not always a crime, it also includes affirmative defense, insanity, self-defense or the execution of convicted criminals. In the United States, youth homicide has especially been seen as a problem of urban areas, due to poverty, limited adult supervision, involvement in drug and gang activities, and school failure. Both homicide rates and suicide rates in the U.S. among people aged 20 to 24 and teenagers aged 15 to 19 have vastly increased since 2001.

In 2024, there were approximately 1.9 homicides per 100,000 inhabitants in El Salvador. Since 2015, when it stood at 103, the murder rate has been dropping annually in this Central American country. Crime current state The region has witnessed a substantial reduction in the number of homicides since 2015, resulting in the most common crimes becoming increasingly more centered on non-lethal offenses and material-related transgressions, which now pose the most prevalent threats. This shift is equally apparent across both genders, with the rate of femicides steadily declining, paralleling a consistent decrease in overall victimization rates. Consequently, El Salvador achieved the ranking of the third safest country within the Latin American homicide rate context. Notwithstanding these notable improvements, a lingering sense of caution endures among the populace, as nearly half of them remain apprehensive about the prospect of falling victim to criminal activities. Main economic problems Following an extended phase marked by elevated inflation, the region continues to grapple with challenges in its efforts to recover. The impact has been most pronounced on the prices of essential food items, rendering them increasingly unaffordable for a population where approximately 20 percent live under poverty conditions. Furthermore, the unemployment rate persists, with one out of every two individuals still seeking employment opportunities. A significant proportion, approximately 60 percent, remain apprehensive about job loss, recognizing the subsequent loss of their primary income source. In response, the government is envisaging an enhancement in both the employment rate and the GDP, albeit with a gradual recovery trajectory following the substantial downturn experienced during the COVID-19 pandemic.

Between June 2023 and May 2024, the most frequent crimes in El Salvador were thefts, with almost 7,000 cases. In total, the public prosecutors of El Salvador reported 15,620 high impact crimes, a considerable decrease when compared to the previous year. The number of offenses in some of the main categories of property crimes is significantly lower than in other years, for example, the number of thefts or robberies of vehicles transporting goods decreased by almost 60 percent in 2020 when compared with 2019. With these numbers, it is no surprise that the approval rate of the current government is over 85 percent. The falling homicide rate In 2015, the homicide rate in El Salvador was over 100 cases per 100,000 inhabitants, one of the highest figures in the world. Nonetheless, during the past years, the rate dropped to less than 20 homicides. El Salvador lived through two of the highest days of violence, with over 74 homicides on March 25th and 26th, 2022. Two days after, El Salvador's government declared a state of emergency to counter gang activity and try to end the wave of violence. Once more, the population seems to back up the government, with over 75 percent of Salvadorans declaring that they feel safe with the current emergency state. The economic cost of violence Violence and crime are two of the main problems society faces in El Salvador and the Central American region. In addition to the lack of security, it also generates economic losses, the cost of violence accounted for over 8,849 million USD in 2022, which is over 15 percent of the Gross Domestic Product (GDP) of the country, almost double the global average. This figure represents the expenditure of a country to deal with the outcome of violence, contain it, and prevent it from spreading and continuing.

This study examined spatial and temporal features of crime guns in Pittsburgh, Pennsylvania, in order to ascertain how gun availability affected criminal behavior among youth, whether the effects differed between young adults and juveniles, and whether that relationship changed over time. Rather than investigating the general prevalence of guns, this study focused only on those firearms used in the commission of crimes. Crime guns were defined specifically as those used in murders, assaults, robberies, weapons offenses, and drug offenses. The emphasis of the project was on the attributes of crime guns and those who possess them, the geographic sources of those guns, the distribution of crime guns over neighborhoods in a city, and the relationship between the prevalence of crime guns and the incidence of homicide. Data for Part 1, Traced Guns Data, came from the City of Pittsburgh Bureau of Police. Gun trace data provided a detailed view of crime guns recovered by police during a two-year period, from 1995 to 1997. These data identified the original source of each crime gun (first sale to a non-FFL, i.e., a person not holding a Federal Firearms License) as well as attributes of the gun and the person possessing the gun at the time of the precipitating crime, and the ZIP-code _location where the gun was recovered. For Part 2, Crime Laboratory Data, data were gathered from the local county crime laboratory on guns submitted by Pittsburgh police for forensic testing. These data were from 1993 to 1998 and provided a longer time series for examining changes in crime guns over time than the data in Part 1. In Parts 3 and 4, Stolen Guns by ZIP-Code Data and Stolen Guns by Census Tract Data, data on stolen guns came from the local police. These data included the attributes of the guns and residential neighborhoods of owners. Part 3 contains data from 1987 to 1996 organized by ZIP code, whereas Part 4 contains data from 1993 to 1996 organized by census tract. Part 5, Shots Fired Data, contains the final indicator of crime gun prevalence for this study, which was 911 calls of incidents involving shots fired. These data provided vital information on both the geographic _location and timing of these incidents. Shots-fired incidents not only captured varying levels of access to crime guns, but also variations in the willingness to actually use crime guns in a criminal manner. Part 6, Homicide Data, contains homicide data for the city of Pittsburgh from 1990 to 1995. These data were used to examine the relationship between varying levels of crime gun prevalence and levels of homicide, especially youth homicide, in the same city. Part 7, Pilot Mapping Application, is a pilot application illustrating the potential uses of mapping tools in police investigations of crime guns traced back to original point of sale. NTC. It consists of two ArcView 3.1 project files and 90 supporting data and mapping files. Variables in Part 1 include date of manufacture and sale of the crime gun, weapon type, gun model, caliber, firing mechanism, dealer _location (ZIP code and state), recovery date and _location (ZIP code and state), age and state of residence of purchaser and possessor, and possessor role. Part 2 also contains gun type and model, as well as gun make, precipitating offense, police zone submitting the gun, and year the gun was submitted to the crime lab. Variables in Parts 3 and 4 include month and year the gun was stolen, gun type, make, and caliber, and owner residence. Residence locations are limited to owner ZIP code in Part 3, and 1990 Census tract number and neighborhood name in Part 4. Part 5 contains the date, time, census tract and police zone of 911 calls relating to shots fired. Part 6 contains the date and census tract of the homicide incident, drug involvement, gang involvement, weapon, and victim and offender ages. Data in Part 7 include state, county, and ZIP code of traced guns, population figures, and counts of crime guns recovered at various geographic locations (states, counties, and ZIP codes) where the traced guns first originated in sales by an FFL to a non-FFL individual. Data for individual guns are not provided in Part 7.
