Definition of Gini in US English:


(also Gini coefficient)


  • A statistical measure of the degree of variation or inequality represented in a set of values, used especially in analyzing income inequality.

    ‘an increase in the Gini coefficient suggests that income is becoming more unevenly distributed’
    • ‘A Gini coefficient of zero indicates a perfectly equal income distribution, and inequality is said to increase as the Gini coefficient gets higher.’
    • ‘Despite relatively high per capita income, the income distribution is skewed, with a Gini Coefficient of 0.7.’
    • ‘In the urban areas, inequality prior to the reforms was remarkably low, with a Gini of 0.185 in 1977.’
    • ‘The greater the income disparity between tenths of households, the greater the bowing of the curve away from the diagonal line and the higher the Gini coefficient.’
    • ‘In less than a decade, the Gini coefficient literally doubled, from around 0.3 to 0.6.’


From the name of Corrado Gini (1884–1965), the Italian statistician who developed the measure.
