Handbook of Longitudinal Research: Design Measurement and Analysis
June 1, 2008
This chapter discusses the process of attrition in longitudinal surveys. Attrition occurs where individuals who initially take part in a longitudinal survey drop-out at a subsequent round of the survey. If attrition levels are high, the quality of the data may be reduced, particularly if those who drop-out have specific demographic or other characteristics. The chapter outlines survey design issues affecting attrition rates and data collection strategies to minimise losses to the sample.
