(3) Family relationship

Column (3): Family relations
Indicate, in this column, the relationship between each member of the household to the head of household. However, if establishing such relationship is difficult to do, define the relationship in relation to another most directly related family member.
Wives shall receive the letter 'E' following by the husband's order number on the form. For example, the head of household's wife shall receive the code E1, the wife of the man number 6 in the household shall receive the code E6.
For children, parents' order numbers are used. For example, a boy whose father is the head of household (order number 1) and whose mother has the order number 3 shall be registered as 'Son 1X3.' Thus, each child is designated by the number of the father and the mother.
However, a child whose father or mother is no longer part of the household shall receive Zero (0) to designate the absent parent.
[Examples are not presented here]
Note that the father's order number always comes before that of the mother when designating children.
For other household members, the census agent must specify the family relation or relations between them and the head of household or another household member. For example, the aunt of the head of household's wife with the number 6 shall be designated as "Aunt of 6".
In the case of servants, friends, and visitors, use such words following by the appropriate numbers. For example, the census agent shall write: friend of 1, Vis. (abbreviation of visitor) or Dom. (abbreviation of servant) of 1.
