Many studies have cast light on the dynamic character of the poverty phenomenon — poverty cycles propagate themselves, and individuals as well as households both enter and exit a situation of deprivation. However, most antipoverty policies are based on indicators constructed with cross-sectional data, which simply reflect the situation of individuals at a particular moment. If an antipoverty policy aims to ensure minimum income and welfare for a family, static measures may underestimate the poverty rate and exclude potential beneficiaries that have frequent deprivation cycles with intervals of non-poverty in between.
