Interviewer instructions
Ask each household about the housing unit it resides in regardless of the type of ownership: How many years have passed since this unit was built? Indicate the answers given in the question: 1 if less than a year; 2 if from 1 to less than 5 years; 3 if from 5 to less than 10 years, etc. If the housing unit has been constructed in stages, take the average number of years. If the ground floor of the housing unit was built 10 years ago and a second floor was added 4 years ago, the age of the housing unit would be 7 years.
