Methodology is another significant issue. Data on income poverty are based on a long-established methodology whose results are solidly enshrined in monetary income thresholds that unequivocally delineate the poor population and, within it, the indigent population. By comparison, the multidimensional, deprivation-based approach to poverty measurement still lacks the methodological consensus enjoyed by income-based measurements, and does not support such a clear-cut interpretation of the results. Nevertheless, it complements the income approach and captures both population groups that both parameters signal as poor, and groups whose income places above the poverty line, but that suffer deprivation in relation to basic needs. The most recent available data indicated that the poorest income quintile (i.e. the 20% of households with the lowest income) on average accounted for of 5% of total income, with the figure varying between 4% (in the Dominican Republic, Honduras and Paraguay) and 10% (in Uruguay). Meanwhile, the wealthiest income quintile accounted for an average of 47% of total income, ranging from 35% (in Uruguay) to 55% (in Brazil) (see table 3).
