This is a brilliant way for participatory assessment of community wellbeing! Pictorial surveys are designed that even illiterate people can fill out, and used to assess the development status of villages/blocks/districts on sectors such as livelihood, water and sanitation, education and literacy, etc. The water survey form is available online: http://www.indiatogether.org/2007/sep/pov-paheli2.pdf
This is similar to the Internal Learning System designed by Prof. Helzi Noponen, where similar pictorial surveys are used by women in rural areas to maintain a daily diary about their family on things such as loan borrowings, child falling sick, grocery purchase, etc. Later, volunteers from NGOs such as Sewa and Pradan sit together with the women and help them analyze their diaries to point out things the women are doing wrong. Simultaneously, it also helps collect data on the lifestyle of people, which can hopefully help in better policy formulation.
