Slave number within holding

1850: Both samples
1860: All three samples

All persons.

SLAVENUM is an identifying number, unique to each slave within a holding. Slaves within a given holding are numbered sequentially using SLAVENUM. (Slave holdings also have their own unique identifiers -- see SERIAL.) A combination of YEAR, DATANUM, and SERIAL provides a unique identifier for every slave holding in the Slave samples; YEAR, DATANUM, SERIAL, and PERNUM uniquely identify every individual in the database.
