  3. Objectives of MCS • To chart the initial conditions of the social, economic and health advantages and disadvantages facing new children in the new century • To capture information for the future • To compare patterns of development with other cohorts • To collect information on previously neglected topics, such as father’s involvement, & child care …………./

  4. …Objectives • To chart the experience of mothers and fathers • To emphasise intergenerational links • To investigate the wider social ecology of the family, including community and services, splicing in geo-coded data when available. • To provide evidence for the National Evaluation of Sure Start and of the Children’s Fund -in England.

  21. MCS: The Future of Data collection • Future surveys are planned for: • Age 5 2005-6 • Age 7 2007-8 etc……. • Possible future design elements • Obtain info on or from daycare provider at 3 • At 5 and 7 Repeat interviews with resident parents • Repeat cognitive and behavioural assessments with children • Collect information from Schools? • Collect information on child’s hospital episodes?
