Researchers at the University of Valencia and Polytechnic University of Valencia in Spain invented the Happiness Index named HAIN in a study using official data from sources such as the UN, World Data Bank and Eurostat. They tested the index on 13 European countries for which all the data they wanted was available: Austria, Croatia, Cyprus, Czech Republic, France, Iceland, Latvia, Lithuania, Portugal, Slovenia, Spain, Sweden and the UK, according to dailymail.co.uk.
