Dark Figure Of Crime
In criminology and sociology, the dark figure of crime, or hidden figure of crime, is the amount of unreported or undiscovered crime. Methodology This gap between reported and unreported crimes calls the reliability of official crime statistics into question, but all measures of crime have a dark figure to some degree. The gap in official statistics is largest for less serious crimes. Comparisons between official statistics, such as the Uniform Crime Reports and the National Incident-Based Reporting System, and victim studies, such as the National Crime Victimization Survey (NCVS), attempt to provide an insight into the amount of unreported crime. Self-report studies are also used in comparison with official statistics and organized datasets to assess the dark of crime. See also * There are known knowns * Under-reporting Under-reporting usually refers to some issue, incident, statistic, etc., that individuals, responsible agencies, or news media have not reported, or h ...

Criminology
Criminology (from Latin , "accusation", and Ancient Greek , ''-logia'', from λόγος ''logos'' meaning: "word, reason") is the study of crime and deviant behaviour. Criminology is an interdisciplinary field in both the behavioural and social sciences, which draws primarily upon the research of sociologists, political scientists, economists, psychologists, philosophers, psychiatrists, social workers, biologists, social anthropologists, as well as scholars of law. Criminologists are the people working and researching the study of crime and society's response to crime. Some criminologists examine behavioral patterns of possible criminals. Generally, criminologists conduct research and investigations, developing theories and analyzing empirical patterns. The interests of criminologists include the study of nature of crime and criminals, origins of criminal law, etiology of crime, social reaction to crime, and the functioning of law enforcement agencies and the penal insti ...

Sociology
Sociology is a social science that focuses on society, human social behavior, patterns of Interpersonal ties, social relationships, social interaction, and aspects of culture associated with everyday life. It uses various methods of Empirical research, empirical investigation and critical analysis to develop a body of knowledge about social order and social change. While some sociologists conduct research that may be applied directly to social policy and welfare, others focus primarily on refining the Theory, theoretical understanding of social processes and phenomenology (sociology), phenomenological method. Subject matter can range from Microsociology, micro-level analyses of society (i.e. of individual interaction and agency (sociology), agency) to Macrosociology, macro-level analyses (i.e. of social systems and social structure). Traditional focuses of sociology include social stratification, social class, social mobility, sociology of religion, religion, secularization, S ...

Reliability (statistics)
In statistics and psychometrics, reliability is the overall consistency of a measure. A measure is said to have a high reliability if it produces similar results under consistent conditions:"It is the characteristic of a set of test scores that relates to the amount of random error from the measurement process that might be embedded in the scores. Scores that are highly reliable are precise, reproducible, and consistent from one testing occasion to another. That is, if the testing process were repeated with a group of test takers, essentially the same results would be obtained. Various kinds of reliability coefficients, with values ranging between 0.00 (much error) and 1.00 (no error), are usually used to indicate the amount of error in the scores." For example, measurements of people's height and weight are often extremely reliable.The Marketing Accountability Standards Board (MASB) endorses this definition as part of its ongoinCommon Language: Marketing Activities and Metrics Pr ...

Crime Statistics
Crime statistics refer to systematic, quantitative results about crime, as opposed to crime news or anecdotes. Notably, crime statistics can be the result of two rather different processes: * scientific research, such as criminological studies, victimisation surveys; * official figures, such as published by the police, prosecution, courts, and prisons. However, in their research, criminologists often draw on official figures as well. Methods There are several methods for the measuring of crime. Public surveys are occasionally conducted to estimate the amount of crime that has not been reported to police. Such surveys are usually more reliable for assessing trends. However, they also have their limitations and generally don't procure statistics useful for local crime prevention, often ignore offenses against children and do not count offenders brought before the criminal justice system. Law enforcement agencies in some countries offer compilations of statistics for various types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uniform Crime Reports
The Uniform Crime Reporting (UCR) program compiles official data on crime in the United States, published by the Federal Bureau of Investigation (FBI). UCR is "a nationwide, cooperative statistical effort of nearly 18,000 city, university and college, county, state, tribal, and federal law enforcement agencies voluntarily reporting data on crimes brought to their attention". Crime statistics are compiled from UCR data and published annually by the FBI in the ''Crime in the United States'' series. The FBI does not collect the data itself. Rather, law enforcement agencies across the United States provide the data to the FBI, which then compiles the Reports. The Uniform Crime Reporting program began in 1929, and since then has become an important source of crime information for law enforcement, policymakers, scholars, and the media. History The UCR Program was based upon work by the International Association of Chiefs of Police (IACP) and the Social Science Research Council (SSRC ...

National Incident-Based Reporting System
National Incident-Based Reporting System (NIBRS) is an incident-based reporting system used by law enforcement agencies in the United States for collecting and reporting data on crimes. Local, state and federal agencies generate NIBRS data from their records management systems. Data is collected on every incident and arrest in the Group A offense category. These Group A offenses are 52 offenses grouped in 23 crime categories. Specific facts about these offenses are gathered and reported to NIBRS. In addition to the Group A offenses, 10 Group B offenses are reported with only the arrest information. History Uniform Crime Reports (UCR) began in the late 1920s when the Committee on Uniform Crime Records, established by the International Association of Chiefs of Police (IACP) in 1927, published the first version of the ''Uniform Crime Reporting Handbook''. With this initiative, the Uniform Crime Reporting program began under the jurisdiction of the Federal Bureau of Investigation. Ove ...

Victim Study
{{short description, Survey of victims of crime A victim study (or victimization survey or victimization study) is a survey, such as the British Crime Survey, that asks a sample of people which crimes have been committed against them over a fixed period of time and whether or not they have been reported to the police. Victim studies may be carried out at a national or local level. Victim studies are canvasses of the public which request them to report any crimes which they have experienced, whether or not they have reported them. This is one of the main ways in which the dark figure of crime is exposed particularly in cases of abuse. Such surveys usually show the level of criminal activity is at least double that which appears in the official crime statistics. Victimisation surveys are usually of two types: *National survey - of a whole country in which people are asked to provide information on crimes which have been perpetrated against them.

National Crime Victimization Survey
The National Crime Victimization Survey (NCVS), administered by the US Census Bureau under the Department of Commerce, is a national survey of approximately 49,000 to 150,000 households - with approximately 240,000 persons aged 12 or older - twice a year in the United States, on the frequency of crime victimization, as well as characteristics and consequences of victimization. The survey focuses on gathering information on the following crimes: assault, burglary, larceny, motor vehicle theft, rape, and robbery. The survey results are used for the purposes of building a crime index. It has been used in comparison with the Uniform Crime Reports and the National Incident-Based Reporting System to assess the dark figure of crime. The NCVS survey is comparable to the British Crime Survey conducted in the United Kingdom. The NCVS began in 1972 and was developed from work done by the National Opinion Research Center and the President's Commission on Law Enforcement and Administratio ...

Self-report Studies
A self-report study is a type of survey, questionnaire, or poll in which respondents read the question and select a response by themselves without any outside interference. A ''self-report'' is any method which involves asking a participant about their feelings, attitudes, beliefs and so on. Examples of self-reports are questionnaires and interviews; self-reports are often used as a way of gaining participants' responses in observational studies and experiments. Self-report studies have validity problems. Patients may exaggerate symptoms in order to make their situation seem worse, or they may under-report the severity or frequency of symptoms in order to minimize their problems. Patients might also simply be mistaken or misremember the material covered by the survey. Questionnaires and interviews Questionnaires are a type of self-report method which consist of a set of questions usually in a highly structured written form. Questionnaires can contain both open questions and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
There Are Known Knowns
"There are unknown unknowns" is a phrase from a response United States Secretary of Defense Donald Rumsfeld gave to a question at a U.S. Department of Defense (DoD) news briefing on February 12, 2002, about the lack of evidence linking the government of Ba'athist Iraq, Iraq with the supply of weapons of mass destruction to terrorist groups. Rumsfeld stated: The statement became the subject of much commentary. In ''The Decision Book'', author Mikael Krogerus refers to it as the "Rumsfeld matrix". The statement also features in a 2013 documentary film, ''The Unknown Known'', directed by Errol Morris. Known unknowns refers to "risks you are aware of, such as canceled flights," whereas unknown unknowns are risks that come from situations that are so unexpected that they would not be considered. Origins Rumsfeld's statement brought attention to the concepts of known knowns, known unknowns, and unknown unknowns, but national security and intelligence professionals have long used a ...

Under-reporting
Under-reporting usually refers to some issue, incident, statistic, etc., that individuals, responsible agencies, or news media have not reported, or have reported as less than the actual level or amount. Under-reporting of crimes, for example, makes it hard to figure the actual incidence of crimes. Under-reporting is a failure in data reporting. Crime Various estimates have been provided in relation to under-reporting of crimes across the world. According to the American Medical Association (1995), sexual violence, and rape in particular, is considered the most under-reported violent crime. Common reasons for individuals not reporting crime include fear of not being believed, insecurity, and fear of getting into trouble. These reasons are most common for not reporting rape. It is commonly assumed that most of the rape cases go unreported; some estimates go up to or above 90%. (See also Rape reporting.) Non-recognition of domestic violence may lead to under-reporting. Murders are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
