Definition
This is a constructed variable that indicates whether the person's spouse lived in the same household and, if so, gives the person number of the spouse (US50A400). Since the 1850 U.S. census did not collect the explicit family interrelationship information, this variable contains information that is documented in the imputed location of spouse (US50A413) variable description.
The method by which probable spouse-spouse links are identified is described inUS50A412; see also "Family Interrelationships" for discussion of NAPP constructed variables.
