Fieldwork for MCS3 (Age 5) in England and Wales finished at the end of October 2006. Almost 12,000 families took part – about 9,800 in England and about 2,100 in Wales. Interviewing in Scotland and Northern Ireland is continuing until the end of the year but we hope that in total over 15,000 families will take part.
Provisional figures suggest that over 90% of families who took part in both the 9 month and Age 3 surveys took part again at Age 5. In addition, about half of families who had been interviewed at the first survey but not at the second took part at Age 5.
