There's a difference between what OP published and living standards.
Norway would rank much higher (migration issues aside), and I don't see how the UK ranks that highly. The minimum wage has become the maximum wage for a lot of people over the last 10 years.
Also the UK population is over 62 million which casts doubt over that data set. 51 million was more like 1990.
EDIT: In fact, isn't Australia's population like 25 million these days?
