In Peru, researchers partnered with implementing organizations Plan International-Peru and Asociación Arariwa. The study focused on households in the rural communities of Canas and Acomayo, located in the department of Cusco, which is among the poorest departments in Peru. To select the poorest members of the communities, the project team conducted a Participatory Wealth Ranking, in which villagers collectively ranked households according to their wealth during a community meeting. Asociación Arariwa conducted a short survey afterwards to verify the results of the ranking.
