For instance, median household income - an income measure which better reflects the actual material living standards of a “typical” household - has evolved quite differently from GDP per capita in a number of countries. It also emphasised the need to go beyond single measures of inequality and argued in favor of looking at the structure and location of inequalities, such as within each half of the income distribution. Putting more focus on the lower-half of the distribution, it documented a relatively widespread tendency for bottom incomes to lose ground relative to median incomes, and, as a result, an increase in relative poverty in the majority of OECD countries. The latter summarizes the level of income by placing progressively more weight on different portions of the distribution.
