[8] What was the age at first marriage of [the respondent]?
Column 8: what is the age at the first marriage of [the respondent]?
(All person aged 10 years or above and persons already married once)
At the time of enumeration, this question should be asked to persons at the age of marriage. Ask persons about their age at the time of their first marriage and write the completed years.
Married means all persons currently married (single marriage, multiple marriage, and remarriage) or persons who are widow/widower, divorced, and separated. All these marital statuses are the status of having married once. If the person enumerated has already married once, ask his/her age at the time of the marriage. While writing the age at the first marriage of the male or female already married once, write the age in completed years at the time of marriage. If any person has married more than once, write the age at the first marriage. Do not write the age for their second or third marriage.
[p. 54]
If any person is unable to say his/her age at first marriage, the age can be written by asking his/her present age and how long he/she has been married and deducting the age difference. E.g. the present age of a person is 45 years and he has been married for 25 years. Then his or her age at the first marriage comes to be 20 years. Similarly, the age at the first child born and the age difference of husband and wife can also be used to be clear about their first marriage.
