Constructing toilets under the Swachh Bharat Mission – India’s national cleanliness programme – may have helped avert roughly 60,000-70,000 infant deaths every year, according to a study.

A team, including researchers from the International Food Policy Research Institute, US, looked at data from nationally representative surveys covering 35 states/Union territories and over 600 districts over 20 years.

The study, published in the journal Scientific Reports, investigated the link between an increase in access to toilets, built under the Swachh Bharat Mission, which was launched by Prime Minister Narendra Modi in 2014, and a drop in deaths among infants and children aged under five from 2000 to 2020.

The results suggested that on average, improving district-level toilet access by 10 percentage points corresponded to a lowering of death rates in infants by 0.9 points and those in under-5 by 1.1 points.

Historically, having access to a toilet and deaths among children have been inversely related in India, the authors said.

They further found that improving toilet coverage by 30 per cent and above in a district corresponded with substantial reductions in infant and child deaths.

“In absolute numbers, this coefficient would scale to an estimated 60,000-70,000 infant lives annually,” the authors wrote.

They said the “novel evidence” of reductions in infant and child mortality, following a comprehensive national sanitation program, potentially indicated the transformative role of the Swachh Bharat Mission.

The findings are in line with evidence from global and South Asian contexts, with multiple studies, that analysed population-level data collected via surveys, indicating that improved sanitation can potentially cut child mortality rates by 5-30 per cent, the researchers said.

They added that recent studies have highlighted the broader benefits of increased access to toilets, including women’s safety, financial savings because of reduced medical expenses and improved quality of life overall.

However, despite the benefits, inequalities in adopting and using toilets persist owing to caste and religion-based discriminatory practices, the authors said.

“Our findings add to the growing body of evidence linking national sanitation campaigns to improved child health outcomes and emphasizes the need for similar interventions in other low- and middle-income countries,” the authors wrote.

They said that studies have also shown local authorities to resort to coercive measures and discrimination to meet campaign targets, which have violated individuals’ rights, particularly those of manual scavengers and people from lower-caste.

“These practices pose challenges to the effective and equitable implementation of the Swachh Bharat Mission, and raise legitimate concerns about the long-term sustainability of hygiene-related behaviour change,” the authors wrote.

Officially launched on October 2, 2014, by the Government of India, the national campaign is aimed at cleaning the country’s streets, roads and infrastructure. One of the objectives of the campaign is to address open defecation in villages by providing access to toilets in all rural households.

As of July 2024, almost 12 crore toilets across rural and urban India had been built in the last nine years, according to a statement by Union minister Hardeep Puri.

Acknowledging the campaign’s progress, the United Nations Department of Economic and Social Affairs said that 50 crore people across 6.3 lakh villages benefitted by 2019.

Further, households in open defecation-free villages – each household equipped with a toilet – saved up to Rs. 50,000 every year, with benefits exceeding costs by 4.7 times for members, it said.

It also warned the opposition not to put pressure on the victim’s family for taking political advantage. The BJP, which has been leading the protests against the TMC government, hit back at chief minister Mamata Banerjee and accused her police of spreading fake news.
