This property is actually quite vague and not used consistently at present

The Gini Coefficient is a mathematical property of an set of numbers. But this property (Gini coefficient (P1125)) does not seem to actually specify quite what those numbers are. For example you might do a Gini coefficient of household incomes, or of individual incomes, or of individual incomes for the working population, or the whole population. You could also use measures of wealth versus income and get wildly different results. There are also different ways of presenting the number; either as the actual coefficient in the range 0-1 or as a percentage in the range 0%-100%. The current constraint expecting 0-100 does not rule out the 0-1 range which is used for example on Taiwan (Q865) without a warning. The English Wikipedia page also uses both styles (coefficient and percentage) without any consistency. Nate Wessel (talk) 19:30, 3 August 2021 (UTC)
