The base scenario used to present the findings is an urban household with four members, including children underage 12, headed by a man aged between 30 and 49 with complete secondary education and a paid job, and no unmet needs in terms of water, sanitary' infrastructure or electricity. This scenario is then used as a starting point to show how the household’s probability of poverty varies in the event of a change in some of the variables. According to this model, household size has the highest impact on poverty probability in Argentina, Brazil, Chile, Panama and Uruguay.
