Measuring one’s standard of living can be a difficult task, as it is subjective. Moreover with measuring tools such as the Human Development Index. Pareto Index and others people quantify important aspects of everyday life and average it to give an indication of one’s living standard. I came across this tool on the OECD’s website, its certainly worth playing around with it and it’s really interesting to see where the UK ranks with other nations. Have a gander.
