Apparemment, la source serait celle-ci (le site de la mission ad hoc). Je n’ai pas vérifié les cartes par état (données uniquement sous forme de tables)

It is “access” to the toilet, not necessarily a toilet in every house. For example if someone’s house is too small to build a toilet or someone is living in an illegal colony, government built a public toilet near their house which they could use .
This data is collected through self declaration by city and village governments. A municipality declares that everyone within its limit has a toilet, then the state government sends an inspector who randomly checks a few of new toilets built.
A proper census of households will be done in 2021.
