To assess the stereotypical views of cohort members and their mothers, we use data from the 1975, 1996, and 2000 sweeps of BCS70, which asks specific questions on women's views of work.
1) To control for multicollinearity, we therefore used the original z-score data from the 1975 BCS70 sweep on mothers' stereotypical views and, for the 1996 and 2000 sweeps, investigated if principal component factor analysis was suitable for standardizing the measures and overcoming the possible problem of multicollinearity.
Another advantage of the BCS70 is that it allows for the econometric testing of different groups of women (mothers and cohort members) and differences in the outcomes experienced by women (homemaking, paid employment, and self-employment).
Our own view is that because the women in the BCS70 are relatively young, they may still be forming views about roles women should and could adopt; the fact that these change over time supports our earlier argument regarding the iterative relationship between stereotypes, social roles, and context.
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.
The five items were measured on a 3-point Likert scale in BCS70 with good internal consistency (alpha = 0.
2002), Progression Routes of Cohort Members: NCDS (1974-2000) and BCS70 (1986-2000).
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).
