Millennium Cohort Study Second Survey: A User's Guide to Initial Findings

This report presents some of the main initial findings of the Second Survey of the Millennium Cohort Study conducted by the Centre for Longitudinal Studies, which is based at the Institute of Education, University of London. It is intended to provide an introduction to potential users of the survey and to stimulate further in-depth and longitudinal analysis

Postponement and childlessness: Evidence from two British Cohorts

This paper starts by reviewing existing projections of childlessness among British men and women. Low current fertility implies high eventual childlessness unless the postponement of parenthood is taken into account. Such re-timing of first births appears to be occurring differentially across social groups. Exploiting the disaggregated evidence of two British cohort studies, the 1958 National Child Development Study and the 1970 British Cohort Survey, this paper investigates the extent of postponement across cohorts and projects its impact on eventual levels of childlessness. Men and women are considered separately in our models of a population stratified by educational attainment. We find the most striking postponement occurring among graduate men. Among graduate women, after taking family building intentions into account, we estimate that about a quarter of 1970 born graduate women will remain childless, rather than something nearer 40 per cent as had been conjectured elsewhere

Influence of a neck compression collar on cerebrovascular and autonomic function in men and women

Objective Neck compression collars have been proposed to reduce injury to the brain caused by head impacts. Our objective was to test if compression of the carotid artery affected the baroreflex and influenced blood pressure control. Methods Cerebrovascular and autonomic responses of healthy young men and women (n = 8 each) to paced deep breathing, Valsalva, and 70o head-up tilt with or without use of a Q-collar were determined. Continuous measurements of heart rate, beat-to-beat blood pressure, transcranial Doppler, and end-tidal gases were obtained. Heart rate variability was measured during supine rest and head-up tilt. Carotid artery and jugular vein cross-sectional area were measured at end-inhalation and end-exhalation using cross-sectional ultrasound images at diastole. Results Wearing the collar reduced carotid cross-sectional area (CSA; P = 0.022; η2 = 0.03) and increased jugular CSA (P = 0.001; η 2 = 0.30). In both men and women, wearing the collar increased systolic blood pressure during Valsalva (P0.05), and there were no effects of the collar on cerebrovascular function, hemodynamics, cardiovagal baroreceptor sensitivity, or heart rate variability (P>0.05) during upright tilt. Conclusion Use of the Q-collar compresses both the jugular vein and carotid artery influencing sympathetic nerve activity in both men and women while influencing brain blood flow in women.York University Librarie

Unpacking Unequal Pay Between Men and Women Across Cohort and Lifecycle

This paper analyses the pay gap between men and women in the two British birth cohort studies using the new data collected in 2000 when their subjects had reached the ages of 30 and 42 respectively. The paper also includes new analysis of improved data on the 1958 cohort at 33 in 1991, and a comparison with our earlier analyses of the 1946 cohort at 32 in 1978 and the 1958 cohort at 33 in 1991. The analysis is of hourly earnings in full-time jobs, where the impact of the Equal Pay Act might be expected to be more complete, given the lack of male comparators in the extensive but low paid part-time employment sector for women. We decompose the wage gap at each age, and the change in the components of the average wage gap over time. We also examine the distribution of estimated gender premia across our samples and relate them to the wage level. For people in their early thirties, the crude wage gap closed between 1978 and 2000, but this was mainly due to improved human capital characteristics of the women in full-time employment at that stage of their lives. Unequal treatment also fell, but not by much. When following the 1958 cohort from age 33 to age 42 in 2000, men’s real wages rose more than women’s. The increased gap was roughly equally due to widening differentials in characteristics and deteriorating rates of remuneration for women entering middle age. Although the 42 year-old employees included women with less exceptional qualifications, who had returned to the labour force with interrupted employment histories, women who had been relatively continuously in employment also experienced the rising gender penalty over time

Gender differences in occupational wage mobility in the 1958 cohort

This article examines the wage growth of British men and women between the ages of 33 and 42 who were employed full time at both of these ages using the 1958 National Child and Development Study. Wage growth is examined in the differences of the log of hourly wage rates reported at the 33 and 42 year old interviews of this cohort study. Men were found to have higher wage growth rewards than women when in higher occupations and be more likely than women to be in these higher wage growth occupations. Women's wages grew more slowly over the period than men's wages because they were located disproportionately in lower growth and feminized jobs. Domestic ties did not explain the differences in wage growth for this group, where the occupational penalties of gender widened. Copyright © 2008 BSA Publications Ltd

Starting life in Scotland in the new millennium : population replacement and the reproduction of disadvantage

Scotland, in line with the rest of Europe, is experiencing low rates of child-bearing and its population is ageing. This does not necessarily mean that people in Scotland are going grey at a faster rate than they used to. Rather, it means that there is an increasing proportion of elderly people in its population, with more people who are growing old than are growing up. The "birth dearth" and "population greying" are not unconnected: low fertility is the key influence on the age structure of a population as well as the rate of population growth
