How many police officers are there in the U.S.? In 2023, there were 720,652 full-time law enforcement officers employed in the United States, an increase from 708,001 the previous year. Within the provided time period, the number of full-time law enforcement officers was lowest in 2013, with 626,942 officers. Employment in law enforcement According to the source, law enforcement officers are defined as those individuals who regularly carry a firearm and an official badge on their person, have full powers of arrest, and whose salaries are paid from federal funds set aside specifically for sworn law enforcement. Law enforcement, particularly when it comes to officers, is a male-dominated field. Law enforcement employees can either be officers or civilians, and federal law enforcement agencies cover a wide area of jurisdictions -- from the National Park Service to the FBI.
Police in the United States The police in the United States have come under fire over the past few years for accusations of use of unnecessary force and for the number of people who are shot to death by police in the U.S. Police officers in the United States are regularly armed, and in comparison, 19 countries, including Iceland, New Zealand, and Ireland, do not regularly arm their police forces.

This statistic shows the number of police personnel per 100,000 residents in Canada and the US from 2003 to 2017. In 2017, there were 187.9 and 206.2 police personnel per 100,000 residents in Canada and the US respectively.

In 2023, there were ******* full-time law enforcement employees in California, the most out of any state in the United States.

The rate of fatal police shootings in the United States shows large differences based on ethnicity. Among Black Americans, the rate of fatal police shootings between 2015 and December 2024 stood at 6.1 per million of the population per year, while for white Americans, the rate stood at 2.4 fatal police shootings per million of the population per year. Police brutality in the United States Police brutality is a major issue in the United States, but recently saw a spike in online awareness and protests following the murder of George Floyd, an African American who was killed by a Minneapolis police officer. Just a few months before, Breonna Taylor was fatally shot in her apartment when Louisville police officers forced entry into her apartment. Despite the repeated fatal police shootings across the country, police accountability has not been adequate according to many Americans. A majority of Black Americans thought that police officers were not held accountable for their misconduct, while less than half of White Americans thought the same. Political opinions Not only are there differences in opinion between ethnicities on police brutality, but there are also major differences between political parties. A majority of Democrats in the United States thought that police officers were not held accountable for their misconduct, while a majority of Republicans that they were held accountable. Despite opposing views on police accountability, both Democrats and Republicans agree that police should be required to be trained in nonviolent alternatives to deadly force.

These data on 19th- and early 20th-century police department and arrest behavior were collected between 1975 and 1978 for a study of police and crime in the United States. Raw and aggregated time-series data are presented in Parts 1 and 3 on 23 American cities for most years during the period 1860-1920. The data were drawn from annual reports of police departments found in the Library of Congress or in newspapers and legislative reports located elsewhere. Variables in Part 1, for which the city is the unit of analysis, include arrests for drunkenness, conditional offenses and homicides, persons dismissed or held, police personnel, and population. Part 3 aggregates the data by year and reports some of these variables on a per capita basis, using a linear interpolation from the last decennial census to estimate population. Part 2 contains data for 267 United States cities for the period 1880-1890 and was generated from the 1880 federal census volume, REPORT ON THE DEFECTIVE, DEPENDENT, AND DELINQUENT CLASSES, published in 1888, and from the 1890 federal census volume, SOCIAL STATISTICS OF CITIES. Information includes police personnel and expenditures, arrests, persons held overnight, trains entering town, and population.

Sadly, the trend of fatal police shootings in the United States seems to only be increasing, with a total 1,173 civilians having been shot, 248 of whom were Black, as of December 2024. In 2023, there were 1,164 fatal police shootings. Additionally, the rate of fatal police shootings among Black Americans was much higher than that for any other ethnicity, standing at 6.1 fatal shootings per million of the population per year between 2015 and 2024. Police brutality in the U.S. In recent years, particularly since the fatal shooting of Michael Brown in Ferguson, Missouri in 2014, police brutality has become a hot button issue in the United States. The number of homicides committed by police in the United States is often compared to those in countries such as England, where the number is significantly lower. Black Lives Matter The Black Lives Matter Movement, formed in 2013, has been a vocal part of the movement against police brutality in the U.S. by organizing “die-ins”, marches, and demonstrations in response to the killings of black men and women by police. While Black Lives Matter has become a controversial movement within the U.S., it has brought more attention to the number and frequency of police shootings of civilians.

Context

Introduction: The dataset used for this experiment is real and authentic. The dataset is acquired from UCI machine learning repository website [13]. The title of the dataset is ‘Crime and Communities’. It is prepared using real data from socio-economic data from 1990 US Census, law enforcement data from the 1990 US LEMAS survey, and crimedata from the 1995 FBI UCR [13]. This dataset contains a total number of 147 attributes and 2216 instances.

The per capita crimes variables were calculated using population values included in the 1995 FBI data (which differ from the 1990 Census values).

Content

The variables included in the dataset involve the community, such as the percent of the population considered urban, and the median family income, and involving law enforcement, such as per capita number of police officers, and percent of officers assigned to drug units. The crime attributes (N=18) that could be predicted are the 8 crimes considered 'Index Crimes' by the FBI)(Murders, Rape, Robbery, .... ), per capita (actually per 100,000 population) versions of each, and Per Capita Violent Crimes and Per Capita Nonviolent Crimes)

predictive variables : 125 non-predictive variables : 4 potential goal/response variables : 18

Inspiration

Your data will be in front of the world's largest data science community. What questions do you want to see answered?

Data available in the dataset may not act as a complete source of information for identifying factors that contribute to more violent and non-violent crimes as many relevant factors may still be missing.

However, I would like to try and answer the following questions answered.

1. Analyze if number of vacant and occupied houses and the period of time the houses were vacant had contributed to any significant change in violent and non-violent crime rates in communities

2. How has unemployment changed crime rate(violent and non-violent) in the communities?

3. Were people from a particular age group more vulnerable to crime?

4. Does ethnicity play a role in crime rate?

5. Has education played a role in bringing down the crime rate?

The Motor Vehicle Collisions person table contains details for people involved in the crash. Each row represents a person (driver, occupant, pedestrian, bicyclist,..) involved in a crash. The data in this table goes back to April 2016 when crash reporting switched to an electronic system. The Motor Vehicle Collisions data tables contain information from all police reported motor vehicle collisions in NYC. The police report (MV104-AN) is required to be filled out for collisions where someone is injured or killed, or where there is at least $1000 worth of damage (https://www.nhtsa.gov/sites/nhtsa.dot.gov/files/documents/ny_overlay_mv-104an_rev05_2004.pdf). It should be noted that the data is preliminary and subject to change when the MV-104AN forms are amended based on revised crash details. Due to success of the CompStat program, NYPD began to ask how to apply the CompStat principles to other problems. Other than homicides, the fatal incidents with which police have the most contact with the public are fatal traffic collisions. Therefore in April 1998, the Department implemented TrafficStat, which uses the CompStat model to work towards improving traffic safety. Police officers complete form MV-104AN for all vehicle collisions. The MV-104AN is a New York State form that has all of the details of a traffic collision. Before implementing Trafficstat, there was no uniform traffic safety data collection procedure for all of the NYPD precincts. Therefore, the Police Department implemented the Traffic Accident Management System (TAMS) in July 1999 in order to collect traffic data in a uniform method across the City. TAMS required the precincts manually enter a few selected MV-104AN fields to collect very basic intersection traffic crash statistics which included the number of accidents, injuries and fatalities. As the years progressed, there grew a need for additional traffic data so that more detailed analyses could be conducted. The Citywide traffic safety initiative, Vision Zero started in the year 2014. Vision Zero further emphasized the need for the collection of more traffic data in order to work towards the Vision Zero goal, which is to eliminate traffic fatalities. Therefore, the Department in March 2016 replaced the TAMS with the new Finest Online Records Management System (FORMS). FORMS enables the police officers to electronically, using a Department cellphone or computer, enter all of the MV-104AN data fields and stores all of the MV-104AN data fields in the Department’s crime data warehouse. Since all of the MV-104AN data fields are now stored for each traffic collision, detailed traffic safety analyses can be conducted as applicable.

The global anti-riot equipment market is experiencing robust growth, driven by escalating civil unrest, increasing terrorist activities, and the rising need for effective crowd control measures by law enforcement agencies worldwide. The market, currently estimated at $2.5 billion in 2025, is projected to exhibit a Compound Annual Growth Rate (CAGR) of 7% from 2025 to 2033. This growth is fueled by technological advancements in less-lethal weapons and defensive equipment, leading to a greater emphasis on minimizing casualties during riot control operations. Key market segments include defensive equipment (such as shields and body armor), which holds a significant market share due to its widespread adoption, and offensive weapons (like tear gas and water cannons), which are crucial for dispersing unruly crowds. Different user segments, including peacekeeping personnel, police forces, armed forces, and private security firms, contribute to the overall market demand. Regional variations exist, with North America and Europe currently dominating the market due to high levels of investment in security infrastructure and relatively high per capita spending on public safety. However, emerging markets in Asia-Pacific are expected to witness significant growth driven by increasing urbanization and rising disposable incomes, fueling further demand for anti-riot equipment. The market's growth is, however, subject to certain restraints. Stringent regulations regarding the use of certain anti-riot equipment and growing concerns about human rights violations related to excessive force present significant challenges. Furthermore, the high initial investment costs associated with advanced technologies can limit market penetration in developing countries. Despite these limitations, the persistent need for effective crowd control and the ongoing development of innovative technologies that minimize collateral damage are expected to ensure sustained growth in the anti-riot equipment market over the forecast period. The increasing adoption of non-lethal weaponry and advanced training programs for law enforcement personnel are positive trends that further reinforce the sector's long-term growth potential. Key players such as Lamperd, Taser International, and Combined Systems are actively investing in R&D to capitalize on these evolving trends.

The global market for law enforcement and firefighting protective clothing fabrics is a significant and rapidly growing sector, projected to be valued at $4,196.1 million in 2025. While the exact CAGR isn't provided, considering the inherent demand driven by increasing safety regulations and advancements in material science, a conservative estimate would place the CAGR within the range of 5-7% for the forecast period of 2025-2033. This growth is fueled by several key drivers. Firstly, the rising awareness of occupational hazards faced by law enforcement and firefighting personnel is pushing for the adoption of more advanced and protective fabrics. Secondly, technological advancements in materials science are leading to the development of lighter, more durable, and more effective protective clothing, enhancing both comfort and safety. Finally, government initiatives and stringent safety regulations across various regions are mandating the use of high-performance protective clothing, further stimulating market expansion. The market is segmented by fabric type (fireproof, corrosion-resistant, and others) and application (police, fire service, ambulance/EMT, military, mining, and others), allowing for targeted product development and market penetration strategies. Key players such as Teijin Aramid, Milliken & Company, and Solvay are at the forefront of innovation, driving competition and further enhancing the quality and availability of these specialized fabrics. The regional distribution of the market reflects the varying levels of economic development and safety regulations across different geographical areas. North America and Europe are expected to maintain substantial market shares due to established safety standards and higher per capita spending on public safety. However, Asia-Pacific is projected to witness significant growth in the coming years, driven by rapid industrialization and urbanization in countries like China and India, leading to increased demand for protective clothing. The market faces certain restraints, including high initial costs associated with advanced protective fabrics and the potential for supply chain disruptions affecting the production and distribution of these specialized materials. Nevertheless, the overarching trend points towards continued expansion, driven by the imperative for enhanced safety and protection in hazardous work environments.

The Death in Custody Reporting Act of 2013 (DICRA) requires the head of each federal law enforcement agency to submit to the U.S. attorney general, information about the death of any person who is detained, under arrest, or in the process of being arrested by a federal law enforcement officer (or by a state or local law enforcement officer while participating in a federal law enforcement operation, task force, or other capacity) being transported to, incarcerated at, or detained at any facility (including immigration or juvenile facilities) pursuant to a contract with a federal law enforcement agency, state or local government facility used by a federal law enforcement agency, or federal correctional or pre-trial detention facility located within the United States (Death in Custody Reporting Act of 2013, P.L. 113-242). The Bureau of Justice Statistics (BJS) created the Federal Deaths in Custody Reporting Program (FDCRP) to collect the data required of federal law enforcement agencies. Federal law enforcement agencies are surveyed on an annual basis about deaths that fall under the scope of DICRA. This data collection includes the 2016 Arrest-Related Death Incident Report (CJ-13A) data and the 2016 Detention/Incarceration Incident Report (CJ-13B) data.

This study was designed to collect comprehensive data on the types of "crime prevention through environmental design" (CPTED) methods used by cities of 30,000 population and larger, the extent to which these methods were used, and their perceived effectiveness. A related goal was to discern trends, variations, and expansion of CPTED principles traditionally employed in crime prevention and deterrence. "Security by design" stems from the theory that proper design and effective use of the built environment can lead to a reduction in the incidence and fear of crime and an improvement in quality of life. Examples are improving street lighting in high-crime locations, traffic re-routing and control to hamper drug trafficking and other crimes, inclusion of security provisions in city building codes, and comprehensive review of planned development to ensure careful consideration of security. To gather these data, the United States Conference of Mayors (USCM), which had previously studied a variety of issues including the fear of crime, mailed a survey to the mayors of 1,060 cities in 1994. Follow-up surveys were sent in 1995 and 1996. The surveys gathered information about the role of CPTED in a variety of local government policies and procedures, local ordinances, and regulations relating to building, local development, and zoning. Information was also collected on processes that offered opportunities for integrating CPTED principles into local development or redevelopment and the incorporation of CPTED into decisions about the location, design, and management of public facilities. Questions focused on whether the city used CPTED principles, which CPTED techniques were used (architectural features, landscaping and landscape materials, land-use planning, physical security devices, traffic circulation systems, or other), the city department with primary responsibility for ensuring compliance with CPTED zoning ordinances/building codes and other departments that actively participated in that enforcement (mayor's office, fire department, public works department, planning department, city manager, economic development office, police department, building department, parks and recreation, zoning department, city attorney, community development office, or other), the review process for proposed development, security measures for public facilities, traffic diversion and control, and urban beautification programs. Respondents were also asked about other security-by-design features being used, including whether they were mandatory or optional, if optional, how they were instituted (legislation, regulation, state building code, or other), and if applicable, how they were legislated (city ordinance, city resolution, or state law). Information was also collected on the perceived effectiveness of each technique, if local development regulations existed regarding convenience stores, if joint code enforcement was in place, if banks, neighborhood groups, private security agencies, or other groups were involved in the traffic diversion and control program, and the responding city's population, per capita income, and form of government.

The number of police officers per 100,000 inhabitants in Nicaragua increased almost by *** during the last 14 years. Robberies involving the use of force were the most common type of crime in Nicaragua in 2021.

The rate of civilians killed by police in the Venezuela is far higher than in comparable developed democratic countries, with 1,830 people killed by police per 10 million residents in 2025. This compares to 69 deaths per 10 million residents in Canada, and seven in Australia - perhaps the two most comparable countries to the United States in many respects. Country with the most prisoners The El Salvador is the country with the largest number of prisoners per capita. This suggests either that they have the most criminals, or that the police make more arrests and judges hand down jail as a more frequent punishment. Costa Rica has the highest burglary rate, seeing almost three times as many break-ins as in the United States, for example. Does weapon ownership contribute to higher number of violent attacks? Other factors may also be at play. One such factor may be gun ownership. If police shootings are more likely to happen in states with a higher number of registered weapons, one could argue that the threat of violence against police makes officers more likely to utilize deadly force. However, countries like Canada also have a high number of individual firearms licenses, indicating that this factor likely does not explain the entire effect. Social factors may also influence this statistic, such as the use of the death penalty. Still, each fatal incident is complex, and the full situation surrounding each involves many factors, meaning that a simple solution is unlikely.

As of November 17, 277 Black people were killed by the police in the United States in 2024. This compares to 201 Hispanic people and 445 white people. The rate of police shootings of Black Americans is much higher than any other ethnicity, at 6.2 per million people. This rate stands at 2.8 per million for Hispanic people and 2.4 per million for white people.

As of November 17, New Mexico had the highest rate of people killed by police out of all U.S. states in 2024, with ***** people per million inhabitants killed by police in that time period, followed by Wyoming with ***** people per million inhabitants killed by police.

In the United States, more men than women are shot to death by the police. As of October 22, the U.S. police shot 904 men and 44 women to death in 2024. In 2023, the police shot 1,107 men and 48 women to death.

This statistic shows per capita expenditures on policing in Canada from FY 1990/91 to FY 2022/23. In FY 2022/23, operating expenditures for police services in Canada totaled 506 Canadian dollars per capita.
