From the informant(s), it is to be ascertained whether or not there has been any improvement or deterioration in the condition of the slum area during the last 5 years in regard to roads (approach and those inside the slum), water supply, street light, electricity, latrine facility, sewerage, drainage system and garbage disposal. The relevant information will be recorded in codes under respective question.
