Calcutta Rescue "Calcutta Rescue (CR) is a medium-sized NGO based in Kolkata, India that focuses on supporting the residents of the city’s slums. CR present the results of its first large-scale study of the poverty experienced by Calcutta Rescue’s service users. It is the largest and most detailed research of its kind conducted in Kolkata in the last two decades. The primary aim of the study was to generate information that would enable CR to rank different slum areas relative to each other in terms of overall, multidimensional impoverishment, and levels of deprivation in specific indicators. This ranking is already helping CR’s management to prioritize resources, and target interventions according to need. The study’s secondary objective was to provide CR with a template methodology that can be repeated and used to capture improvement over time, or after specific interventions."
