Lies, Damned Lies, And Statistics: Why London’s Murder Rate Is Not Higher Than NYC’s

March 20, 2019

By Dan Kaszeta

Translations: Русский

On April 3, 2018, an article in USA Today stated that the murder rate in London exceeded that of New York City for the first time. A large numbers of articles and posts have since repeated this claim.

These various articles and posts continue to be cited as evidence that London is more dangerous/violent than New York. Social media posts have amplified this claim, and taken it from a singular statement noting a particular odd situation valid for a short period of time, stretching it into making broader claims. Some commentators have used a “London has more murders than New York City” false narrative to make various points about immigration, terrorism, and gun laws.

Was The Claim True?

In the narrowest sense, the claim was actually true for a short period of time. There was a short stretch in early 2018 in which there were fewer than expected murders in New York City and an unusually high number of murders in London.  This occurred in February and March of 2018.  However, even during that quarter-year, there were more murders in New York City than London due to a great disparity in January of 2018.

The media eventually reversed course. Later, several articles correctly stated that the murder rate had reverted back to the historical average, with London having fewer murders.

How To Do A Murder Rate Comparison

The fair way to compare murders is on a per capita basis, and one generally accepted method is numbers of murders per year per 100,000 of population.  Annual rates are more statistically useful for murder rates than daily, weekly, or even monthly rates.

Even in the large cities like London and New York, murders are not always a daily event. There may be days or even weeks without murders, and they are not always evenly spread across the calendar.

There simply are not enough murders in either city for daily or weekly figures to be considered accurate portrayals.  There are individual days on the calendar when there is a murder in New York and not one in London, or vice versa.

If one were to engage in statistical cherrypicking you could say that the murder rate is infinitely higher in New York or infinitely higher in London on a particular day. It would, statistically, be true. But practically, it would be meaningless. The fair way to do comparisons of murder rates for such cities is via an annual rate, whether it be for a calendar year or a 12 month rolling average.

First, to do this fairly, one has to consider population figures. The New York City versus London comparison is often made because the populations of the two cities are roughly comparable. However, the last census in the U.S. was in 2010 and the last one in the UK was in 2011. Therefore, population estimates are useful for this work, although we should always keep in mind that these are estimated figures.

The most recent official estimated figure for New York City’s population is 8,622,298 as of July 1, 2017.  The official estimated figure for greater London at the same point in time was 8,825,001.  These figures will be used for calculation of relative rates as they are from the exact same point in time and based on official figures. (Note: If someone has a more recent data set for both cities on the same date, please contact me via the comments section and I will update accordingly.

Getting to the bottom of murder rates, comparatively speaking, should not be too hard. Unlike some statistics, it is relatively easy to make a one-for-one comparison — a dead body is a dead body.  Dead bodies, particularly ones that are dead because someone committed a murder, are counted and categorised. Articles are writteen about them. In the U.S. and UK, murders rarely go un-reported or under-reported.

Other categories of crime, such as assaults and frauds, are far more difficult to compare, as many crimes go unreported and definitions vary widely.  What constitutes an assault varies from state to state in the U.S., so even internal comparisons are difficult.

Data Sources

For the essential test case of Greater London versus New York City, there are excellent sources of data.  The London Metropolitan Police statistics website (here) has both current and historic figures.  The New York City Police Department has a similar website (here) with very good statistics.

It can be difficult to do a direct comparison at times, as the London statistics are reported on a monthly basis and it is often weeks before the previous month’s statistics are posted.  New York’s, on the other hand, are updated every week. As the weeks do not usually correspond with the end of the month, getting the figures to overlap exactly is not always easy.

It is also important to note that the London Metropolitan Police area does not cover the City of London. This is often confusing to people outside of London or outside the UK.  The City of London is only a small (2.9 square kilometres) part of greater London, comprising what had been Roman and Medieval London. It is now, principally, a financial district. It has a separate governance structure and a separate, much smaller, police force, the City of London Police. The City’s actual population of residents is quite low, estimated at less than 10,000 people in 2018.  Murders in the City of London are rare, but not unheard of. There was one in 2018.

What Was The Situation In 2018?

According to New York’s figures, there were 295 murders in 2018.  This yields a murder rate of 3.42 per 100,000 population in 2018.

According to London figures, there were 128 murders in 2018 in the London Metropolitan Police boroughs of Greater London, i.e. everything except the City. The Daily Mail claimed a total number of murders in greater London as 134, and the Telegraph also repeated this figure. This figure of 134 includes one murder from the City of London.  I cannot account for the discrepancy between the 128 and 133 figures for the Metropolitan Police. However, assuming the higher figure of 134 murders as correct, the murder rate for London for 2018 is 1.52 per 100,000 population.

We can therefore see that New York’s murder rate was actually more than twice than that of London’s.

The situation for 2019 shows an even starker difference in murders than 2018. New York has had 53 murders in the period from January 1 to March 3, 2019. During the first two months of 2019, London has had 16 murders.  The 3-day discrepancy in the reporting periods is due to the difference between monthly and weekly rates not exactly lining up (March data for London was not yet published as this report was drafted on March 18, 2019).

Terrorism Deaths

Several accounts on social media have claimed that the 2018 figures for London are artificially low because they do not include deaths from terrorism.  This is rather a pointless argument as the number of terrorism deaths in London in 2018 was zero.

State of New York vs City of New York

Various interlocutors on social media have tried to confuse the state of New York with the City of New York. This makes for an unfair comparison as New York state has a much larger area and population than London, whereas both London and New York City are densely populated cities of approximately equal population.

For the record, New York State had 547 murders in 2017, yielding a murder rate of 2.8 per 100,000 population (the comparable report for 2018 is not yet available).

Historic Trends

This graphics, meanwhile, show the general historic trends in New York City and London, and are useful for making historic comparisons:

 

Update as of July 2019:

As this issue continues to come up on social media, here are the updated figures at the halfway point in 2019.  So far, in 2019 through 2 June, London has had 75 murders through 8 July 2019.  In 2019 through 30 June, New York City has reported 135 murders.

    The murder rate discrepancy between London and NYC is fairly predictable due to the infinitely easier accessibility to firearms in New York, coming across state borders. Guns kill more effectively, faster and with less effort- than do knives.
    What is noteworthy is that with a comparable size population and police force, London now has 1.5x more recorded robbery and assault, 3x more rape, and 6x more burglary, than NYC.

      Hello, where did you find this information regarding the last past of your comment? (Not starting a debate lol, I’m genuinely interested)

      What you’re basically saying is that the tougher gun restrictions in New York only benefit criminals?

      From what I understand the six cities with the highest gun control have the highest murder rate (from guns that is).

      In the UK the 1920 Firearms Act was supposed to make people safer. It didn’t work. Recorded violent crime is up over 600 times in a century.

    London has become a multi culti hell hole. It’s changed from 76 when I was born to what it is now. New York and London have similar populations, but London is 136 square miles bigger I understand! Can you imagine that, we have so much more space, no guns, but a lot of violence. If we had guns on the streets of London, we’d be out of control because with knives at close range, it’s dangerous out there. Dare I say with a gun it’s less mentally involving, but with a knife you have to go up to the person and stick it right in them.

      I moved to London in 1971 – never looked back. The population has grown a lot since then but if you aren’t a young man, the experience of crime of all sorts has gone down. For young (very young) men in areas with gangs, things are a bit different.

      I must tell you that you are wrong because If everyone owns a gun, anyone who attempts to use the guns for crimes, the people who are at the scene of the crime who just want to buy something will engage the lone or few criminals engaging in crime and shoot them. This will eventually make criminals too afraid to be a criminal and the ones that are brave enough will get shot anyways, forcing them to find alternatives such as piracy and hacking, those of which aren’t much of a big deal because we now have vpns and other online protections. Britain, know for it’s strict gun control laws, has some of the highest murder rates, in the world compared to America. However, these two countries are different so I “found” an example in the US, alone. Introducing Prohibition, During the 1920s, Congress passed the 18th Amendment which banned the legal production and sale of Alcohol which was pushed by wives who didn’t want their husbands to drink. This didn’t stop them though, people who enjoyed the effects of alcohol wanted to continue to drink, they decided to make their own alcohol using tubs or buying it illegally from gangs and Rum-Runners so banning a product won’t get rid of it.

        Houston, new Orleans and many other cities in the USA have lax gun laws and high murder rates. NYC has very strict gun laws. Yes, they can get snuck in.

    Recorded crime rates in the UK include threats and cases where no physical violence was used so are hard to compare with international statistics, and because even large-scale victim surveys are national rather than local the only available breakdown by borough is from recorded crime, largely calls for service from the police which do not necessarily reflect underlying levels of crime.

      In this article, I compare actual murders, which have a dead body which can be counted. I’m only comparing this. Not sure what point you are trying to make.

    The definition of the offence of murder in the UK is quite narrow. Many acts that cause death are treated as manslaughter.
    A young man was stabbed to death against our garden fence during a drug deal related argument. The stabber was convicted of manslaughter asvintent could not be proven.
    So this will not count as a London murder. Just saying as I agree with Dan’s argument

    You can’t take the statistics of reported crime as accurate, the British Police produced them. “In 2014, a report by the UK Parliament’s Home Affairs Select Committee said there was “strong evidence” of under-recording, which was exaggerating the rate of decrease in crime. Police forces throughout England and Wales were found to have an “utterly unacceptable” rate of accurately recording crime”….. And in 2019, 7 out of 39 forces were classified as inadequate (HIMFRS)

        That’s not a relevant rebuttal to the criticism. Besides, you’re the one using the statistics to make a point. You are the one who has to prove they’re accurate. Lies, damn lies and statistics, indeed.

      Actually, no. The New York and London statistics in this post refer to murders, not “solved murders”. They include murders in which nobody has been charged, etc. Please refrain from such erroneous posting.

    Yep, the fake crime stats for London are used by right wingers for their selfish agendas. In the US, the fanatic rights use this to justify crazy gun laws. In the UK and Europe, it’s used by racists to bash immigration and multiculturalism and support the tragedy of Brexit.
    Conservatives never tell the truth and will use fake stats all the time. Whether it be on Planned Parenthood, Sharia law, Climate Change, etc. They always lie and cheat to their anti-intellectual and slow-witted base.

    London is safe and so is New York it’s just the population that makes the cities look dangerous. High population is going to mean more murders it’s common sense. New York is one of the safest cities in the US if you look at other cities in the US like East St. Louis they had a population of 26,662 people with 37 murders, that’s a murder rate of 138.7. If London had that murder rate there would be 12,000+ murders a year and same with New York. And guns don’t really matter (I’m not with guns or against them) if somebody is going to kill somebody their going to do it anyway they can like a knife or a car.

    I MUST correct you, ive lived in NYC all my life, out of the 50 states, we have one of the lowest death by firearm per 100,000 people, 3rd right behind Hawaii and Mass., from the turn of the century, gun violence was lower in the city. NYC has tight gun restrictions, you cannot just carry your gun around (at least youre not suppose to), once you get it, it is suppose to stay whatever location; unless stipulations blah blah blah. but you more have to be worried about being punched in the face than stabbed or shot.
