The Gini coefficient is widely used as a measure of income or wealth distribution among a population. The higher the value, the more income or wealth is concentrated among a small fraction of the population. For example, using World Bank numbers, Mexico has a Gini value of 45.4, while Norway comes in at 27.0.
