Question No. 13: In what period was this dwelling built?

Information that is obtained in this question will permit us to determine the amount of dwellings that have been built in each space of time and at the same time to verify the statistical study of the construction in the period between censuses.

Mark a single circle according to the response of the person. Read the given alternatives in the questionnaire.
Some times a situation can be presented in which a person does not know the date of construction. In this case it is recommended to request information from other routes (neighbor, lessee, etc.), when you are enumerating apartment buildings or tenement houses, the information should be equal for all the dwellings. If finally you do not succeed in obtaining the required information, mark circle 4 "Not known."
