Definition
This is a constructed variable that indicates whether the person's father lived in the same household and, if so, gives the person number of the father (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 father (US50A410) variable description.
The method by which probable child-father links are identified is described in US50A409; see also "Family Interrelationships" for discussion of NAPP constructed variables.
