The Indian government announced a national plan to analyze whether people are using toilets as part of a program launched by Prime Minister Narendra Modi three months to improve hygiene in the country using paid survey sites.
Health inspectors go door to door to see if people use the toilets. They noted earlier surveys only building toilets and no use.
The Indian government says it has built half a million household toilets since October.
According to the UN, half of the 1,200 million people in India do not have toilets in their homes, causing serious problems of hygiene in public spaces, involving the transmission of diseases.
