This paper provides a review of the theory of the measurement of poverty. The axiomatic theory is described and axiomatic properties of poverty indexes are related to assumptions on their functional form. The notion of poverty ordering is then introduced and the relations between the poverty orderings that can be defined from classes of poverty indexes with well defined functional form properties and the notions of first order and second order stochastic dominance are reviewed.
