As stated previously, all this calls for discussions and agreements on the definition of poverty and its dimensions, in the light of a more comprehensive notion of well-being. Whatever the conceptual and methodological approach used, one basic condition for a more thorough multidimensional measure is to increase the availability of data and to improve their quality. Indeed, in several countries the reductions noted between 2008 and 2012 have been sharper than those observed between 2002 and 2008. The most recent data available indicate that the poorest quintile (that is, the 20% lowest-income households) receive on average 5% of total income, with shares that vary between less than 4% (in the Dominican Republic, Honduras and Paraguay) and 10% (in Uruguay), while the share of total income in the richest quintile averages 47%, ranging from 35% (in Uruguay) to 55% (in Brazil) (see figure 1.16). These changes have occurred gradually and are scarcely perceptible in year-on-year variations, but they are evident in a comparison over longer periods.
