Description

NAMELAST is an alphabetic variable reporting the person's last name, as recorded by the enumerator on the census form. A question mark embedded in a name indicates an illegible character. A question mark and space preceding a name means the entry was difficult to read and the name is the best interpretation possible. An exclamation point indicates that the entire entry was illegible. An asterisk indicates that the field was blank.
