Description

Definition

NAMELAST is an alphabetic variable giving a person's full last name. It will primarily be of use to researchers linking the IPUMS historical census data to other sources of demographic data, or researchers whose research topic involves naming patterns. Because of the length of this variable (32 columns), and the size of the dataset, other researchers should not select this variable.

NAMELAST is used to produce the variable SURSIM which assigns the same code to all persons within each household who had a shared surname.
