  Given some specification of the kind of equality that is under consideration, it is clear what it means to say of a number of people that they are equal in the stated respect. If we are concerned with equal utility, then a group has equal utility when all have exactly the same. If we are concerned with equality of dollar holdings, then people are equal when all hold exactly the same number of dollars. But saying this does not yet suggest a way of determining, in general, whether inequality is greater in one situation than in another, when different people hold different amounts of the good that we are concerned to equalize in the two situations. Inequality can be measured in different ways, and no measure seems to be strongly supported by common sense intuition about the meaning of equality. (See Sen 1997 and Temkin 1993). This entry usually abstracts from this issue by supposing that we can unequivocally determine, for any ideal of equality, how to measure degrees of inequality across the board.
