Intervention group
Rural villages in which Gram Vikas has fully implemented its water supply and sanitation (Mantra) intervention.
Intervention villages must: 1) be within 3 hours travel to the study office in Brahmapur, 2) have started the intervention by January 2003, and 3) have completed the intervention by January 2013.
|
Village-level reticulated water supply with distribution to household taps; pour-flush pit latrines.
|
|
Control group
Rural villages that have been matched with intervention villages on demographics and other criteria.
The sampling frame for control villages is limited to those: 1) within 3 hours travel to the study office in Brahmapur, and 2) within Gram Panchayats which do not include an intervention village and are not adjacent to an intervention village, to minimize spillover effects.
In addition, both intervention and control villages must appear in the Government of India Census in 2001.
