The second cohort managed by CLS is the British Birth Cohort Study of 1970, now known as BCS70.
It is a network of nine research resources, bringing together the three studies featured here (NCDS, BCS70 and MCS), two other national birth cohort studies, the 1946 birth cohort (MRC NSHD and Life Study); the new enlarged household panel study, Understanding Society, and three locally based cohorts.
Twenty-four per cent of the 0 to 4 year olds in the BCS70 were also reported to have gone to state nursery schools before starting school, but the most frequently reported pre-school provision for this cohort was the playgroup with 52 per cent of children (apparently) attending this type of setting (see note 6).
The BCS70 results do not, unfortunately, provide an unambiguous account of how much the children with working mothers were 'exposed' to different child care arrangements while their mothers worked.
Women doing manual (or routine) jobs were about 30 per cent less likely to be using formal care in both MCS and BCS70 (where the inclusion of father's occupation made little further contribution to explaining variation).
