Since October 2014, the Government of India (GOI) has worked towards the goal of eliminating open defecation by 2019 through the Swachh Bharat Mission (SBM). In 2014, several of the co-authors reported on a survey of rural sanitation behaviour in North India (Coffey et al 2014) conducted by the Research Institute for Compassionate Economics (rice). Different statistical methods produce slightly different numbers, but results from a wide range of approaches used concur that approximately 40% to 50% of rural people in these states defecated in the open in late 2018. The 2014 survey used a multistage sampling strategy to select households: first, districts were purposively selected to match the state-level trend in rural open defecation between the 2001 and 2011 Censuses; second, villages were randomly drawn using proportional-to-size sampling from a frame taken from the Government of India’s District Level Health Survey; third, households were selected using an in-field randomisation technique similar to that used for Pratham’s Annual Status of Education Report (ASER) survey.
