Interpretation
2 1–9, 11–13 SUCCESS: The relationship was clearly identifiable using information
from one pair member, while the relationship code from the other pair
member was missing.
2 10 FAILURE: A spouse-spouse 1 relationship was definitively established
using information from one pair member, while the relationship code
from the other pair member was missing. It was unclear whether the
pair had children in the household.
3 1–8, 12, 13 SUCCESS: Relationship information was conflicting between the pair
members, but conclusions were drawn anyway for some parent-child
pairs, some sibling-sibling pairs, and some spouse-spouse 1 pairs using
either information outside the household roster or logical reasoning. 2
4 15–25 FAILURE: Relationship information was not identifiable. Information
was in conflict between the pair members, where one pair member
indicated relationship of interest and the other did not. However, ages
supported a relationship of interest (may be used to limit imputation).
1 The pair relationship labeled "spouse-spouse" includes partner-partner pair relationships.
2 In the case of potential parent-child pairs, further evidence that a parent-child relationship was involved or not involved was
obtained by looking at the FIPE3 variable, by whether a stepparent had a spouse that corresponded to a child's parent or by the
ages of the respondents. For spouse-spouse relationships, two situations occurred: in the case where the respondents were not
legally married, the children of one pair member were considered the children of the pair in the household, even though they
were not identified as such by the other pair member. In the case where only one pair member referred to the other as a "married"
or "unmarried partner," if both had the same children, they were considered "spouse-spouse-with-children." The other pair
member was usually referred to as a "roommate" or "other nonrelative."

6.2.3 Creation of Covariates for Imputing Pair-Level Variables
For pairs where the relationship was not clear due to missing pieces of the household
roster, or where pairs could not be determined because the relationship codes did not match,
imputation was required. In stages two and three, imputation also was required for missing
multiplicities and household-level person counts. In all three stages, the PMN method was used
to impute missing values, which required the fitting of models. Since the imputation was
