Definition
This variable indicates the person's imputed relationship to the head of the household.
The variable was created using logical inference and statistical imputation, since the 1850 census did not collect explicit family interrelationship information. The most important determinants for the imputed relationship to the head of the household are the order in which names appeared on the census form, surnames similarity, age, sex, occupation, and birthplace. For most of the cases, the NAPP assigns the imputed relationship according to logical rules based upon these determinants. For the remaining cases, the NAPP uses a hot deck allocation procedure that examines a wider set of determinants that probabilistically assign the imputed relationship.
