Recently, another measure, the Human Development Index (HDI), which combines jobs, income, along with access to medicine, life expectancy, and education has become prominent. The UN HDI is measures a country's level of human development. While there is a strong connection between a high HDI score and a prosperous economy, it is not always the case. The top 47 countries by HDI have scores ranging from 0.793 in Barbados to 0.955 in Norway. Many countries having an HDI of 0.788 and over (as of 2010), are also listed by IMF or CIA as "advanced" (as of 2009). The country of Bhutan started the idea of Gross National Happiness (GNH), to measure how happy people actually are. They felt the GNH was as important as GDP, and this idea has spread beyond Bhutan.
