So, we carried out a third party field survey of these districts to see the reality this year. The QCI surveyed 70,000 households before ranking them. It studied more than 1,050 households in plain regions, while in hilly areas, over 350 households were inspected, a report said. The survey on sanitation was conducted based on four parameters: percentage of households having access to safe toilets and their usage (40 per cent weightage), households having no litter around (30 per cent); average score of cleanliness (out of 100) around public places (20 per cent) and households having no wastewater around (10 per cent), officials said.
