Description:  

This is the first edition of a report on response in the Millennium Cohort Study as it progresses from sweep two onwards.

MCS: Technical Report on Sampling - 3rd Edition

Author:   Ian Plewis, with contributions from Lisa Calderwood, Denise Hawkes, Gareth Hughes and Heather Joshi

Description:  

The third edition of what is expected to be a continually expanding description of the design and sampling outcomes of the Millennium Cohort Study as it progresses from sweep to sweep. It covers all the material (except for the appendices) from the first edition (August 2001), some of which has been slightly amended. It includes the rationale for the  underpinning design, the definition of the study population, the target sample for Sweep 1 and how it was selected and obtained. In addition, it includes final response rates for Sweep 1 (cohort at nine months of age), and the computation of sampling errors for the Sweep 1 data, taking into account the effects of stratification and clustering. These results were included in the second edition (May 2003) but have been slightly amended and expanded to take account of corrections to the dataset after the initial deposit with the Data Archive. This third edition also includes new material, in particular analyses of non-response for Sweep 1.

MCS: Technical Report on Sampling - 4th Edition

Author:   Ian Plewis, with contributions from Lisa Calderwood, Denise Hawkes, Gareth Hughes and Heather Joshi

Description:  

This is the fourth and final edition of a document that describes the design and sampling outcomes of the first sweep of the Millennium Cohort Study. It includes all the material from the third edition together with some minor amendments to take account of corrections incorporated into the dataset deposited at the Data Archive in June 2006. It also includes some details on multiple births and the cohort child’s age at interview that were not in the third edition. Details about response after sweep one can be found in Plewis and Ketende (2007).

MCS1 - Technical Report on Instrument Development and Fieldwork

Author:   Andrew Shaw, Lisa Calderwood

Description:  The central objective of this technical report is to document NatCen’s contribution to the first sweep. The next chapter (2) details the development work undertaken to prepare the first sweep, which included a pilot survey and dress rehearsal. Readers needing information solely on the main survey and not on the ‘hows and whys’ of development, may wish to skip this chapter. Chapter 3 outlines the sample design and explains the procedures for respondent selection. Chapter 4 summarises the final survey instrumentation and Chapter 5 describes how the fieldwork was conducted. Chapter 6 discusses the progress of fieldwork, quality control thereof and issues which arose during this phase. Chapter 7 covers the verification of information on the achieved sample and the dispatch of thank you letters to respondents. Chapter 8 accounts for the survey response and Chapter 9 describes
procedures for coding, editing and preparation of the data. Various documents used in the study are to be found in the Appendix.

MCS1: Infant Mortality in the Millennium Cohort Study (MCS) Sample Areas

Author:   Andrew Cullis

Description:  

This report investigates how many children in the birth cohort (from which the MCS was sampled) did not survive long enough to be included in the survey which took place at 9 months.  Not only would infant mortality within the birth cohort result in some cases with early deaths being missed out of MCS, but the possibility of differential infant mortality between social groups could bias the sample of survivors.
