Atkinson, Marlier and Wolf (2010) argue that selecting a particular set of dimensions is equivalent to attributing zero weight to other aspects which are not included, and question whether the various items should be weighted the same in the different countries. The inclusion of material items has also been questioned on the basis that the social meaning of goods and activities essential for social participation differs from one country to another (Till and Bffe, 2010). In turn, Fusco, Guio and Marlier (2010) warn that this method combines diverging concepts of poverty (income as opposed to deprivation) and mixes different standards for making them operational (the situation in one country relative to a European standard). Adopting the 60% median line as an indicator of the cost of meeting social needs yields six countries with relative poverty rates above absolute poverty. These are Argentina, Brazil, Chile, Costa Rica, Panama and Uruguay. Relative poverty decreased between 2002 and 2010, but not as much as absolute poverty.
