Description
Line number - 1968-2025
Unicon Corporation made the following notes about this variable:
Note to those interested in matching: This variable is transcribed by the interviewer from rotation to rotation. So this should be a unique identifier for an individual within the household. In the initial rotation (mis = 1), the value should be equal to perid. In 1976, the questionnaire went through a major revision and it was not until 1979, when the CPS began to include lineno again.
