Prosperity Index scores for all countries are shown above. Each factor in the Index is scaled so that zero represents the world average. The Material Wealth and Life Satisfaction scores for each country are calculated based on a weighted average of the Index factors and rounded to the nearest integer. The weights for the Index factors are assigned based on statistical analysis of historical data. The overall Prosperity Index rank is based on the average of a country's Material Wealth and Life Satisfaction ranks. An equals sign ('=') indicates a tie.
