POPRULEH explains the criteria by which the variable POPLOC linked the person to a probable father in pre-1950 datasets.
In the pre-1950 datasets, child-father links were established according to four basic rules, and POPRULEH gives the number of the rule that applied to the link in question.
POPRULEH works the same way for all countries. A lower-numbered rule (greater than 0) takes precedence over a higher numbered rule. The codes for POPRULEH are as follows:
0 = No father of this person present in the household.
1 = Unambiguous relationship. This rule covers four basic cases, and occurs when the person linked is 10 to 69 years younger than the probable parent. All relationship pairings are not available in every sample. The allowable relationship pairings are as follows:
Child linked to head or spouse/unmarried partner of the headHead or sibling linked to parentSpouse or sibling-in-law linked to parent-in-lawChild/child-in-law linked to head or spouse2 = Grandchildren. Potential fathers are males listed as child or child-in- law in RELATE 13-79 years older than persons listed as grandchildren and who share the grandchild's surname. If there is more than one potential father, we used relative positions in the household, age and marital status to decide the link.
3 = Other relatives and nonrelatives. Link to a preceding person with a plausible relationship pairing of child-to-father, where the father is 13-79 years older, is ever-married, and shares the child's surname. The father must immediately precede the child or all intervening persons must also be linked to the father as spouse or child. Permissible relationship pairings are as follows (child to father):
Nephew/niece to sibling or sibling-in-lawCousin to aunt/uncleOther relative to siblingGrandchild to other relativeOther relative to other relative (RELATEH code 1000, 1001, 1061)Non-relative to non-relative (RELATEH code 1100-1303)7 = If a child is linked to a mother (see MOMLOC and MOMRULEH), and that mother is linked to a husband who has not been linked to the child by another rule, the husband is linked to the child as a stepfather, regardless of the age gap between child and husband.
Consistency checks: If a husband and wife were both linked to the same father, the best father link was chosen based on detailed relationship (RELATEH) and proximity within the household. If a person is linked to two parents who are not linked to each other, remove one of the parental links on the basis of proximity within the household.
