Source-derived summary

Figures on crime in London are based primarily on two sets of statistics: the Metropolitan Police (MPS) reported statistics, and the Mayor's Office for Policing & Crime (MOPAC) victim surveys. The Crime Survey for England and Wales (CSEW) contains London data, but its sample size is usually insufficient for precise estimates of London numbers.

Following a history of significant changes to UK national police reporting standards and systems, accurate trend data for many police-reported crimes in London has not been available until about 2002. Rises in violent crime from about 2012 onwards have, in common with the rest of the United Kingdom, been partially due to the effects of these improved reporting practices over time.

Greater London is generally served by three police forces; the MPS which is responsible for policing the vast majority of the capital, the City of London Police which is responsible for The Square Mile of the City of London and the British Transport Police, which polices the national rail network and the London Underground. A fourth police force in London, the Ministry of Defence Police, do not generally become involved with policing the general public. London also has a number of small constabularies for policing parks. Within the Home Office crime statistics publications, Greater London is referred to as the London Region.

Data collection and publication

Since the late 1990's, there have been multiple changes to the way the Metropolitan and national police forces in the UK gather, compile and report crime statistics. With the exception of homicide, which can be reliably compared over time, trend analysis over multi-year periods was very difficult until approximately 2012, particularly for non-homicide violent crimes.

Editorial summary

This brief starts where responsible research should: with the source description of “Crime in London” as overview of crime in London, England. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—2002, 2012, 1990—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Crime, London and overview can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as overview of crime in London, England. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 1, 2026. The linked authority identifier is Q5185324. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2002, 2012 and 1990.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
