This report will utilise the information available in sweeps 1-3 (from birth to when the child is age 5) of the MCS, to explore the following research questions:

  • Do children born in the Millennium in Wales have different health outcomes at birth to those born elsewhere in the UK?
  • How do cross country differences in health and cognitive development change as the child ages (until age 5)?
  • What determines these cross country differences in child health and child development?
  • What intra-regional differences exist in child health and cognitive development in Wales? What determines this intra-regional variation?
