Abstract:

Background:
The original objectives of the first MCS survey, as laid down in the proposal to the Economic and Social Research Council (ESRC) in March 2000, were:Additional objectives subsequently included for MCS were:The first sweep (MCS1) interviewed both mothers and (where resident) fathers (or father-figures) of infants included in the sample when the babies were nine months old, and the second sweep (MCS2) was carried out with the same respondents when the children were three years of age. The third sweep (MCS3) was conducted in 2006, when the children were aged five years old, the fourth sweep (MCS4) in 2008, when they were seven years old, and the fifth sweep (MCS5) in 2012-2013, when they were eleven years old.

Sub-sample studies:
Some studies based on sub-samples of MCS have also been conducted, including a study of MCS respondent mothers who had received assisted fertility treatment, conducted in 2003 (see SN 5559). Also, birth registration and maternity hospital episodes for the MCS respondents are held as a separate dataset (see SN 5614).

Weighting:
Users should note that the weighting section in the 'Guide to the Datasets' document recommends analysis in Stata, as SPSS is not currently able to weight the data using the survey design factors. The depositor is working on a solution for SPSS, but this is not yet available. A Stata version of the dataset is available for download by registered users, alongside the SPSS and tab-delimited versions.

MCS web pages:
Further information about the MCS can be found on the Centre for Longitudinal Studies website.

Participants for the Millennium Cohort Study: Survey of Mothers who Received Assisted Fertility Treatment, 2003 were drawn from existing MCS respondents. Consenting parents who had reported having any medical infertility treatment for the pregnancy covered by MCS were sent a postal questionnaire which asked more detail about their experiences of infertility treatment. Much of the resulting statistical analysis involved comparing the women who had received different types of infertility treatment, either with each other or with women who had received no such treatment. All analyses allowed for the clustered, stratified sample design, with re-weighting included where necessary to allow for the different sampling proportions.

For the second edition (March 2008), a new version of the data file was deposited, with the family serial number variable (famsrno) replaced by a new serial number variable, mcsid (MCS Research Serial Number). The documentation remains unchanged.

Main Topics:

Topics covered included when and where fertility treatment was sought, the type of treatment received (including drugs prescribed), fertility treatment for previous pregnancies, and costs and overall experience of treatment.
