Zhrnutie	Equivalence scales convert a household's total income or consumption into a measure of the living standard of its members, adjusting for the fact that larger households need more resources but also share them — there are economies of scale in housing, utilities, and durables, and children typically cost less than adults. Dividing household resources by the scale yields equivalized income, the per-equivalent-adult quantity that makes welfare comparable across households of different size and composition. The theory traces to Deaton and Muellbauer's treatment in Economics and Consumer Behavior (1980), and Buhmann and colleagues' 1988 cross-country study showed that inequality and poverty rankings can be strikingly sensitive to which scale is chosen.	The Gini coefficient is the most widely used single-number summary of inequality in a distribution such as income or wealth. Introduced by the Italian statistician Corrado Gini in 1912, it equals twice the area between the Lorenz curve and the line of perfect equality, ranging from 0 when everyone has the same amount to a maximum approaching 1 when one unit holds everything.
