Here you can search our series of working papers, dating back to 1983. These papers use data from our four cohort studies and cover a wide range of topics, from social inequalities and mobility, to physical health, education and cognitive development. Other papers in the series seek to improve the practice of longitudinal research. At the present time, we are only able to accept papers if at least one author is a member of the CLS research team. Some of the working papers below will subsequently have been published in peer-reviewed journals.

Using rich and nationally representative longitudinal data from the UK Millennium Cohort Study about young people, their families, and wider social contexts, the current report aims to provide an understanding of the antecedents and development of offending behaviours. The focus is on self-reported offending when cohort members were age 17, with information on influential factors drawn from throughout childhood.
Morag Henderson, Alice Sullivan, Jake Anders and Vanessa Moulton identify patterns of subject and qualification choices made at age 14. Previous ‘subject choice’ research has focussed on the later stages of educational trajectories, particularly Higher Education. But the choices made at early branching points can limit pupils’ subsequent options, potentially contributing to educational inequalities. This paper identifies the patterns of GCSE subjects chosen by a cohort of young people born in 1989/1990, making use of the Next Steps data (formerly the LSYPE) which is linked to the National Pupil Database. The authors develop an approach to measuring the academic selectivity of subjects and qualifications, examining the roles of social class, parental education, income, gender and ethnicity in determining participation in these curriculum groupings. Using measures of prior attainment from age thirteen, the authors address the question of whether curriculum differentials simply reflect differences in prior attainment or whether they actually operate above and beyond existing inequalities.
Keywords: Next Steps, LSYPE, social class, parental education, income, gender, ethnicity, inequality,
Alice Sullivan, Sam Parsons, Francis Green and Dick Wiggins examine pathways to high socio-economic positions for men and women born in Britain in 1970. Their analysis draws on the 1970 British Cohort Study (BCS70), exploiting data from birth to age 42. The paper provides a comprehensive account of the way in which cognitive and educational attainment mediate the link between social origins and elite destinations in terms of social class and earnings in mid-life. The authors assess the roles of private and selective secondary schools, and of high-status universities and fields of study. The finding is that, once a sufficiently detailed picture of educational attainment is taken into account, education fully explains the link between social origins and top social class destinations.
Keywords: British Cohort Study 1970, BCS70, social mobility, education, social class.
Jessamy Lowe uses data from MCS Sweeps 1-4 to explore the early occurrence of the adiposity rebound (normal age 5-7 years), defined by the IOTF as a difference in z-scores between two ages ‘greater than 0.67’.
This additional weight represents an increase in fat mass as opposed to lean mass, with ‘early rebounders’ showing rates of gain in fat mass more than double those of ‘late rebounders’. This results in children who experience EAR developing different body compositions, with increased (predominantly central) adiposity.
Keywords: Millennium Cohort Study, adiposity, weight gain, fat mass, BMI.
This paper uses data from the BCS70 to learn more about the ‘social-levelling effect’ of having a degree: it’s known that graduates from different social backgrounds tend to do equally well in the first few years following graduation, but how does this picture evolve in the longer-term?
Keywords: BCS70, education, social class, social mobility, degree, graduate, gender equality.
The National Child Development Study (NCDS) Age 55 Survey adopted a sequential mixed-mode design whereby study members were first invited to participate online, with non-respondents being followed up by telephone.
This CLS working paper provides a summary of the design decisions taken to maximise the quality of the data collected via the web, and is intended to aid those considering administering a similar survey. The paper describes the design of the web survey (in the mixed mode context) and the contact strategy employed to encourage participation via the web.
This CLS working paper aimed to investigate whether taking part in out of school activities during primary school is linked with end of primary school attainment and social, emotional and behavioural outcomes, for all children and specifically for children from economically disadvantaged backgrounds.
This CLS working paper uses data from the 1970 British Cohort Study (BCS70) to investigate the effect of private schools on pupils’ self-esteem and locus of control at ages 10 and 16, and on aspirations and high-value network access at age 16. The paper also examines the effect of these factors on earnings in mid-career and their hypothesised significance for understanding the private-school earnings premium achieved in later life.
Key words: non-cognitive skills, wages, locus of control, self-esteem, pay, private school, aspiration, networks, social mobility.
This CLS working paper aims to identify whether Lesbian, Gay and Bisexual (LGB) youth are more at risk of bullying. It uses data from Next Steps (previously known as the Longitudinal Study of Young People in England).
Key words: Bully-victimisation, England, lesbian, gay and bisexual (LGB), Next Steps, sexual minority.
This CLS working paper examines how young people’s early transitions into the labour market have changed between cohorts born in 1958, 1970, 1980, and 1990. It uses sequence analysis to characterise transition patterns and identify three distinct pathways in all cohorts.
This CLS working paper uses data from Next Steps (previously known as the Longitudinal Study of Young People in England) to examine inequalities in students choosing to study STEM (Science, Technology, Engineering and Mathematics) subjects. It looks at disparities in uptake by students’ family background, gender and ethnicity.
Key words: Subject choice, STEM, A-level, Degree, Ethnicity, Gender, Socio-economic background, Intersectional, Logistic Regression.
The UK Millennium Cohort Study is the first large-scale social survey to use a highly innovative mixed-mode approach for the collection of pre-coded time diaries among adolescents.
This CLS working paper focuses on issues surrounding research design, instrument development, and implementation of the time diaries. It discusses the construction of an activity code scheme relevant for young people growing up in contemporary Britain, and present the three time diary instruments.
Key words: longitudinal; methodology; Millennium Cohort Study; mixed-mode; new technologies; time diary surveys; time-use record; time-use research
This CLS working paper explores change in pupils’ educational expectations between ages 14-16 systematically across white, Indian, Pakistani, Bangladeshi and Black Caribbean adolescents under a psychometric framework using cohort panel data from Next Steps (formerly known as the Longitudinal Study of Young People in England).
