Crime statistics in the United Kingdom

no crimingcrime statistics
For less frequent crimes such as intentional homicide and armed robbery, reported incidences are generally more reliable, but suffer from under-recording; for example, no criming in the United Kingdom sees over one third of reported violent crimes being not recorded by the police.
As with crime statistics elsewhere, they are broadly divided into victim studies and police statistics.

Victim study

victim studiesvictimisation surveysVictimisation rate
Two major methods for collecting crime data are law enforcement reports, which only reflect crimes that are reported, recorded, and not subsequently canceled; and victim study (victimization statistical surveys), which rely on individual memory and honesty.
Such surveys usually show the level of criminal activity is at least double that which appears in the official crime statistics.

National Crime Victimization Survey

National Crime SurveyNational Crime Victimization Survey (NCVS)
The U.S. has two major data collection programs, the Uniform Crime Reports from the FBI and the National Crime Victimization Survey from the Bureau of Justice Statistics.
The survey results are used for the purposes of building a crime index.

Crime prevention

However, the European research suggests that "increased use of crime prevention measures may indeed be the common factor behind the near universal decrease in overall levels of crime in the Western world", since decreases have been most pronounced in property crime and less so, if at all, in contact crimes.
It targets social programs and law enforcement at neighborhoods where crime rates are high.

Dark figure of crime

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.

Moral statistics

Examples include statistics on crimes (against persons and property), illiteracy, suicide, illegitimacy, abortion, divorce, prostitution, and the economic situation sometimes called pauperism in the 19th century.
