A team of researchers at the Universitat Politècnica de València (UPV) and Universitat de València (UV) have developed a new index to measure a country’s happiness. Named HAIN (HAppiness INdex), it is based on five areas – development, freedom, solidarity, justice and peace, each of which is evaluated based on quantitative variables taken from various official databases such as the UN’s Human Development Reports, the World Bank Open Data and Eurostat.
