Since October 2014, the Government of India has worked towards the goal of eliminating open defecation by 2019 through the Swachh Bharat Mission. In June 2014, the results of a survey of rural sanitation behaviour in North India were first reported. The results from a late 2018 survey that revisited households from the 2014 survey in four states—Bihar, Madhya Pradesh, Rajasthan, and Uttar Pradesh—are presented. Although rural latrine ownership increased considerably over this period, open defecation remains very common in these four states. There is substantial heterogeneity across states in what the sbm did and how. These outcomes suggest the need for a transparent, fact-based public dialogue about the sbm, its costs and benefits, and its accomplishments and means.

An analysis of child height-for-age using the newly released data from the National Family Health Survey-4 indicates that the average child height increased by about four-tenths of a height-for-age standard deviation between 2005 and 2015. Although important, this increase is small relative to India’s overall height deficit, and relative to economic progress; children in India remain among the shortest in the world. It is unsurprising that the increase in height-for-age has been modest because none of the principal factors responsible for India’s poor child height outcomes have substantially improved over the last decade. Familiar patterns of regional, sex, and caste disadvantage are reflected in child height in 2015.

India has far higher open defecation rates than other developing regions where people are poorer, literacy rates are lower, and water is relatively more scarce. In practice, government programmes in rural India have paid little attention in understanding why so many rural Indians defecate in the open rather than use affordable pit latrines. Drawing on new data, a study points out that widespread open defecation in rural India is on account of beliefs, values, and norms about purity, pollution, caste, and untouchability that cause people to reject affordable latrines. Future rural sanitation programmes must address villagers’ ideas about pollution, pit-emptying, and untouchability, and should do so in ways that accelerate progress towards social equality for Dalits rather than delay it.

Children in West Bengal and Bangladesh are presumed to share the same distribution of genetic height potential. In West Bengal they are richer, on average, and are therefore slightly taller. However, when wealth is held constant, children in Bangladesh are taller. This gap can be fully accounted for by differences in open defecation, and especially by open defecation in combination with differences in women's status and maternal nutrition.
