When it comes to the number of homicides, Dublin is losing
Dublin has more cases than London. London has far lesser homicides compared to Dublin. In a year, Ireland would have a lot of homicide cases, a number of which would occur in Dublin. Not only that but when crimes happen in Dublin, rarely do you find anyone charged.

Suffice to say; one is most likely to be a victim of homicide in Dublin than in London. When one looks at the figures, there is a 9% difference between the two cities.
But if one should look at the numbers, Dublin is not on the top when it comes to the number of homicides in the region. Scotland tops the list with a murder rate of 1.6 for every 100,000 inhabitants. Scotland tops the list in the whole British Isles region.
Northern Ireland is in second place together with Ireland (where Dublin is). Both these countries have a homicide rate of 1.2 for every 100,000 people.
England (where London is) and Wales are taking the last spot with a homicide rate of 1.1. This should be 1.1 homicides for every 100,000 inhabitants.
But while homicides are more common in Dublin than in London, it is a different story about robbery.
Robbery is twice as common in London compared to Ireland. This can partly be because London is more touristy than Dublin. Especially in touristy areas, pickpocketing is a common offense. This multiplies the number of robbery cases in London compared to that of Dublin.
For every 100,000 inhabitants, there would be about 137 cases of robbery in London. In Dublin, it would be 56 cases of robbery for every 100,000 inhabitants. This is a huge disparity when it comes to robbery cases.
This is also the same story when it comes to cases of assault.
Some contend that victims of assault in Dublin may not be that common. For some, it may be because victims are not as willing to report cases as those in London.
This claim may not be, at all times, substantiated. But it may ring true at some point.
Another factor that may cause the disparity between these numbers is the definition. Definitions of the word “assault” between two cities may differ. This means that not all assault cases in London may be usually considered as such in Dublin.
London has about 730 cases of assault for every 100,000 inhabitants. The city is only second next to Scotland, where there would be 1,487 cases for every 100,000 people.
On the other hand, Dublin has only about 90 cases of assault for every 100,000 individuals. This may be a huge difference when one compares it.
One could probably surmise that Dublin is far safer than London. But it depends on which angle you look at.
Because if we talk of smaller crimes like robbery and assault, yes, Dublin may be safer.
But if we look at homicide cases, Dublin has a higher number than London.
It actually depends on how you look at it.
Because no matter which city you are in, there is always a need to exhibit caution. Without it, one can always be a victim of crimes, even in the safest city in the world.
