Definition
This variable reports why the NAPP variable spouse's location in the household (US50A411) linked the person to a probable spouse. The NAPP establishes spouse-spouse links according to seven basic rules, and this variable reports the number of the rule for the link in question. If a link could be made according to more than one rule, the lowest-numbered rule was applied. See spouse's location in the household (US50A411) and"Family Interrelationships" for more information.
The following codes are included in this variable:
0 = No spouse of this person present in household.
1 = A married woman and a married man were linked because she was listed immediately after him on the form and both persons' relationship to the household head/householder, when compared with one another, justified a link. The following pairings justified links:
Head/Householder - Wife/Husband
Son - Daughter-in-law
Daughter - Son-in-law
Father - Mother
Father-in-law - Mother-in-law
Brother - Sister-in-law
Brother-in-law - Sister
2 = Same pairings as in rule 1, but the married woman was listed immediately before the married man on the form.
3 = A married woman and a married man who did not appear adjacently on the form were linked because
a) they had one of the relationship sets listed in rule 1;b) the woman was at least 13 years old;c) the man was at least 15 years old;d) the man was not more than 25 years older than the woman; ande) the woman was not more than 10 years older than the man.
4 = A married woman whose relationship to the head was not listed, or did not match the married man's as specified in rule 1, was still linked to a married man because he was listed immediately before her on the form, their ages fit parts b, c, and d of rule 3, and the resulting link did not link a non-relative to a relative.
5 = Same as rule 4, but the married woman was listed immediately before the married man on the form.
