Satisfaction with the condition of dwelling is a combined indicator based on the information on the number of rooms in the dwelling, technical condition of the dwelling (whether the roof is leaking; whether the walls, floor or foundation are damp; whether it is too dark in the dwelling; whether the noise level is high) and crime and pollution in the vicinity of the dwelling. The value of the combined indicator may range from 0 (not satisfied) to 100 (completely satisfied).
