Since HDI (Human Development Index) - an index of population and their capabilities, is the ultimate criteria for determining the human living conditions on a country, it is the most accurate measure of the <u>standard of living</u> on it. The table shows us that a country with a high GDP (Gross Domestic Product) index, does not necessarily rank as high on the HDI (Take China, for example, which has the world's second higher GDP, but ranks the 101st position on HDI).
On other hand, Norway, which is on 23rd rank on GDP, occupies number 1 on both GNI and HDI.
