That's clearly not the same type of analysis. It's looking at claims per family rather than claims per x number of population and is also looking at ethnicity rather than nationality.It isn't though. If the UK Gov is the source, you are most likely to be a benefit claimant if you are white british.

You'd also need to look at what each of the studies meant by "benefits". When most people talk about benefits they're often not talking about things like the state pension or child benefit, which that study does consider benefits and which are the most widely received.
