Having looked at this, they have a few things that aren't quite right. But that's not surprising given how tough it is to compare countries that define things differently.

I've only lived recently in Germany and the UK, so I can speak for those, but for example the "maternity" comparison is very skewed because of the (admittedly confusing) way that Germany defines "paid time with your child after they are born". There are basically two phases to it, with different names and conditions. The first is the 14 weeks of 100% pay which is listed on the website, but afterwards there is what's called Elternzeit ("parents time") which is partially paid (starts at 65% if I remember right) and is at least 14 months, but can be extended with slightly different conditions.

So the vast majority of the benefit is not being included in this comparison.
