MCS - Technical Report on Response (Second Edition)

Author:   Sosthenes C. Ketende

Description:  This is the second edition of a report on response in the Millennium Cohort Study as it progresses from sweep 2 onwards. This edition includes material on sweep 2 and 3 and covers the evolution of the population and sample after sweep 1, allowing for the families who were included in the study for the first time at sweep 2. It presents response rates for sweeps 2 and 3. It also covers the correlates of different types of unit non-response at sweep 3, and gives references to published articles detailing correlates of different types of non-response at sweep 2. This report does not cover item non-response, because response is very high in nearly all items except income. Family income missing data and new derived variables will be covered in a separate Technical Report. Section 1 to 4 covers material in the first edition of this series with minor changes mainly typo corrections and section 5 to 8 covers the new materials.
