In 2017, the state and local government police-protection expenditures in the United States as a share of Gross Domestic Product (GDP) was **** percent. This figure has stayed relatively consistent since 2000.

In the fiscal year of 2020, the New York City Police Department had an operating budget of *** billion U.S. dollars. This is considerably higher than the second-highest, the Los Angeles Police Department, whose operating budget was **** billion U.S. dollars in the same year.

In 2016, the total operating budget of local police departments in the United States varied by size of population served. Police departments serving populations with over *********** residents had a total budget of about ***** billion U.S. dollars.

This data collection was undertaken to gather information on the extent of police officers' knowledge of search and seizure law, an issue with important consequences for law enforcement. A specially-produced videotape depicting line duty situations that uniformed police officers frequently encounter was viewed by 478 line uniformed police officers from 52 randomly-selected cities in which search and seizure laws were determined to be no more restrictive than applicable United States Supreme Court decisions. Testing of the police officers occurred in all regions as established by the Federal Bureau of Investigation, except for the Pacific region (California, Oregon, and Washington), since search and seizure laws in these states are, in some instances, more restrictive than United States Supreme Court decisions. No testing occurred in cities with populations under 10,000 because of budget limitations. Fourteen questions to which the officers responded were presented in the videotape. Each police officer also completed a questionnaire that included questions on demographics, training, and work experience, covering their age, sex, race, shift worked, years of police experience, education, training on search and seizure law, effectiveness of various types of training instructors and methods, how easily they could obtain advice about search and seizure questions they encountered, and court outcomes of search and seizure cases in which they were involved. Police department representatives completed a separate questionnaire providing department characteristics and information on search and seizure training and procedures, such as the number of sworn officers, existence of general training and the number of hours required, existence of in-service search and seizure training and the number of hours and testing required, existence of policies and procedures on search and seizure, and means of advice available to officers about search and seizure questions. These data comprise Part 1. For purposes of comparison and interpretation of the police officer test scores, question responses were also obtained from other sources. Part 2 contains responses from 36 judges from states with search and seizure laws no more restrictive than the United States Supreme Court decisions, as well as responses from a demographic and work-experience questionnaire inquiring about their age, law school attendance, general judicial experience, and judicial experience and education specific to search and seizure laws. All geographic regions except New England and the Pacific were represented by the judges. Part 3, Comparison Data, contains answers to the 14 test questions only, from 15 elected district attorneys, 6 assistant district attorneys, the district attorney in another city and 11 of his assistant district attorneys, a police attorney with expertise in search and seizure law, 24 police academy trainees with no previous police work experience who were tested before search and seizure law training, a second group of 17 police academy trainees -- some with police work experience but no search and seizure law training, 55 law enforcement officer trainees from a third academy tested immediately after search and seizure training, 7 technical college students with no previous education or training on search and seizure law, and 27 university criminal justice course students, also with no search and seizure law education or training.

Supplementary Empirical Teaching Units in Political Science (SETUPS) for American Politics are computer-related modules designed for use in teaching introductory courses in American government and politics. The modules are intended to demonstrate the process of examining evidence and reaching conclusions and to stimulate students to independent, critical thinking and a deeper understanding of substantive content. They enable students with no previous training to make use of the computer to analyze data on political behavior or to see the results of policy decisions by use of a simulation model. The SETUPS: AMERICAN POLITICS modules were developed by a group of political scientists with experience in teaching introductory American government courses who were brought together in a workshop supported by a grant from the National Science Foundation in the summer of 1974. The American Political Science Association administered the grant, and the Inter-university Consortium for Political and Social Research was host to the workshop and provided data for most of the SETUPS. The modules were tested and evaluated during the 1974-1975 academic year by students and faculty in 155 classes at 69 universities and colleges. Appropriate revisions were made based upon this experience. This collection comprises 15 separate modules: (1) Political Socialization Across the Generations, (2) Political Participation, (3) Voting Behavior, The 1980 Election, (4) Elections and the Mass Media, (5) The Supreme Court in American Politics, Court Decisions, (6) The Supreme Court in American Politics, Police Interrogations, (7) The Dynamics of Political Budgeting, A Public Policy Simulation, State Expenditures, (8) The Dynamics of Political Budgeting, A Public Policy Simulation, SIMSTATE Simulation, (9) The Dynamics of Political Budgeting, A Public Policy Simulation, SIMSTATE II Simulation, (10) Fear of Crime, (11) Presidential Popularity in America, Presidential Popularity, (12) Presidential Popularity in America, Advanced Analyses, (13) Campaign '80, The Public and the Presidential Selection Process, (14) Voting Behavior, The 1976 Election, and (15) Policy Responsiveness and Fiscal Strain in 51 American Communities. Parts 8 and 9 are FORTRAN IV program SIMSTATE sourcedecks intended to simulate the interaction of state policies. Variables in the various modules provide information on respondents' level of political involvement and knowledge of political issues, general political attitudes and beliefs, news media exposure and usage, voting behavior (Parts 1, 2, and 3), and sectional biases (15). Other items provide information on respondents' views of government, politics, Ronald Reagan and Jimmy Carter as presidents, best form of government, government spending (Part 3), local police, the Supreme Court (Parts 4 and 15), the economy, and domestic and foreign affairs. Additional items probed respondents' opinions of prayer in school, abortion, the Equal Rights Amendment Law, nuclear energy, and the most important national problem and the political party most suitable to handle it (Part 3). Also included are items on votes of Supreme Court judges (Part 5), arrest of criminal suspects and their treatment by law enforcement agencies (Part 6), federal government expenditures and budgeting (Part 7), respondents' feelings of safety at home, neighborhood crime rate, frequency of various kinds of criminal victimization, the personal characteristics of the targets of those crimes (Part 10), respondents' opinions of and choice of party presidential candidates nominees (Part 13), voter turnout for city elections (15), urban unrest, and population growth rate. Demographic items specify age, sex, race, marital status, education, occupation, income, social class identification, religion, political party affiliation, and union membership.

In the fiscal year 2024, the total annual budget of the National Police Agency (NPA) in Japan amounted to approximately ***** billion Japanese yen. The budget increased compared to around ***** billion Japanese yen in the previous year.

In 2021, the allocated budget for the National Police Agency in South Korea was approximately ***** billion South Korean won. The budget levels had fluctuated throughout the past decade.

In the fiscal year 2020, personnel expenses accounted for the highest share in the total budget of the Prefectural Police (PP) in all ** Japanese prefectures, with approximately *** trillion Japanese yen. Facility expenses only amounted to around ***** billion Japanese yen of the total budget. The prefectural government covers the expenses for their own PP, but can be supported by subsidies from the national government.

During the period between 2014 and 2020, the Indonesian National Police had a total budget of about *** billion Indonesian rupiah for its digital activities. It was approximately *** times higher than the budget of the Ministry of Tourism. The digital activities done by the Indonesian National Police may be related to the country's efforts to increase its national strategy for cybersecurity.

China spent approximately **** trillion yuan on public security in 2023, a ********* increase in the past decade. The public security expenditure includes state security, police, domestic surveillance, armed civil militia, and other measures to deal with public disturbances. Guangdong, Jiangsu, and Xinjiang were the top three provinces in terms of public security spending.

In the fiscal year 2023, the total annual budget of the National Police Agency (NPA) in Japan amounted to approximately 300.6 billion Japanese yen. The budget increased compared to around 289 billion Japanese yen in the previous year.

The crime rate in the United Kingdom was highest in England and Wales in 2024/25, at **** crimes per 1,000 people, compared with Scotland, which had **** crimes per 1,000 population, and Northern Ireland, at **** crimes per 1,000 people in 2023/24. During this time period, the crime rate of England and Wales has usually been the highest in the UK, while Scotland's crime rate has declined the most, falling from **** crimes per 1,000 people in 2002/03, to just **** by 2021/22. Overall crime on the rise In 2024/25, there were approximately **** million crimes recorded by the police in England and Wales. Although this was a slight decline on the previous two years, it was still far higher than during the mid-2010s. While crime declined quite significantly between 2002/03 and 2013/14, this trend went into reverse in subsequent years. While there are no easy explanations for the recent uptick in crime, it is possible that reduced government spending on the police service was at least partly to blame. In 2009/10, for example, government spending on the police stood at around **** billion pounds, with this cut to *****billion in 2013/14. One of the most visible consequences of these cuts was a sharp reduction in the number of police officers in the UK. Between 2010 and 2017, the number of officers fell by 20,000, although the number of officers returned to pre-austerity levels by the 2020s. A creaking justice system During the period of austerity, the Ministry of Justice as a whole saw its budget sharply decline, from *** billion pounds in 2009/10 to just **** billion by 2015/16. Although there has been a reversal of the cuts to budgets and personnel in the justice system, the COVID-19 pandemic hit the depleted service hard in 2020. A backlog of cases grew rapidly, putting a strain on the ability of the justice system to process cases quickly. In 2022, for example, it took on average *** days for a crown court case to go from offence to conclusion, compared with *** days in 2018. There is also the issue of overcrowding in prisons, with the number of prisoners in England and Wales dangerously close to operational capacity in recent years.
