In 2006, the Demographic and Household Survey for Benin ran a module on household poverty to ascertain people's perceptions of necessities and the degreeto which they felt these needs were met for them and their families.  Questionnaires(in English) were translated into the main languages of Benin (French, Adja, Bariba, Fon, Dendi, Ditamari and Yoruba), and interviews conducted mainly in French but also in Adja, Bariba, Fon, Dendi, Ditamari, and Yoruba.The  English and French lanuage version of this module can be downloaded below.
