The study of the distribution of income summarizes a nation's social organization and the outcome of the forces of social change. The measurement of income distribution itself is a type of social score-card which enumerates the resolution of claims by competing groups for the economy's output. As an indication of social justice, the income distribution measures as well the extent to which different groups share in a nation's economic progress.
