Millennium Cohort Study Wave 8

Lead Research Organisation: UNIVERSITY COLLEGE LONDON
Department Name: Social Science

Abstract

The Millennium Cohort Study (MCS) is a large, nationally representative birth cohort study following the lives of over 19,000 cohort members since their infancy. The study has now run for seven sweeps, providing an incredibly rich picture of lives of this generation. The cohort is nearing the end of the critical developmental period spanning late childhood to early adulthood, marking a vital point in the life course and a key turning point in the study.

This proposal makes the case for an eighth sweep of face-to-face data collection at age 22, and for ongoing support for data enhancements, including through linkages of administrative, geographical and other novel data, to maximise its value and impact. In so doing, it will add to the wealth of data already collected through seven major face-to-face sweeps of data collection (at ages 9 months, 3, 5, 7, 11, 14 and 17 years) and three online COVID-19 surveys (at ages 19, 20).

The eighth sweep will be instrumental in studying transitions to adulthood, including in employment, education, partnerships, fertility and residence. It will provide a unique resource for understanding the evolution of inequalities in a range of domains, including in mental health and obesity, which have been major issues facing this generation since childhood. With widespread concern about the impacts of the COVID-19 pandemic on this generation, striking at a time when the cohort are navigating critical transitions in education and the labour market, the new data collection is ideally primed to capture its influences on young people.

As the first major adult sweep of the study, it will be critical to establish the constructs and associated measures to include at age 22, since in the interests of longitudinal continuity these will then determine the domains and measures that will be included throughout adulthood. The measures chosen will have the dual objective of combining continuity with innovation, both to facilitate studies of within- and cross-generational change, alongside drawing on the most up to date science and leveraging newly emerging technologies where appropriate. To determine the scientific content of the study, we will take an approach that combines a strong resource-driven model with clear research questions. The major areas we plan to cover include but are not limited to education, learning and investment in skills; employment transitions, economic circumstances, the nature of work; mental health and wellbeing; physical health and health behaviours; psychosocial skills and cognitive development; the role of the family; identity and attitudes; digital connectedness; partnership formation and fertility.

We will deposit the data at the UK Data Service within one year of the completion of fieldwork, accompanied by extensive documentation for users to ensure it is widely accessible. We will conduct research on the data to showcase early findings from the study, focusing on highly policy-relevant areas with major gaps in evidence, and will engage with a range of stakeholders including policymakers, the media and third sector in order to maximise impact from the study.

Title Original artwork celebrating the Millennium Cohort Study's 21st annniversary 
Description To mark the 21st anniversary of the Millennium Cohort Study, we commissioned three artists to each produce an artwork to represent and celebrate the study. The three artists we selected for this project, Cat Sims, James Hutch, and Pevê Azevedo, were chosen for their different styles. We worked with the artists closely to determine which characteristics of the study they would focus on in their pieces. We printed the three pieces as a set of three postcards, which we sent to each study member in March 2023, to thank them for their contribution so far. On the back of each postcard we included a thank you message from one of our researchers, explaining how they have used the study in their work, as well as some words from the artist about their piece. In addition to the postcards, we produced 21 fine art quality prints of each piece in A4 size to give to study members through a ballot; 218 study members entered the ballot to receive one of these and the recipients were selected at random.

Description The UK Millennium Cohort Study (MCS) Age 23 Survey is a large-scale longitudinal study tracking individuals born in 2000-2002. Historically conducted through face-to-face (F2F) interviews, the study sought to determine whether a sequential mixed-mode approach-starting with web-based surveys and following up with F2F interviews for non-respondents-could improve participation rates while maintaining data quality.

A randomised experiment was conducted with 3,000 participants (1,500 in each group), of a total sample of 13,713. Within these 3000, we randomly allocated half to a group who were first invited to take part via web with non-respondents followed up face-to-face ('sequential mixed-mode'), with the remaining half allocated to face-to-face only. Allocation to the experiment and to each experimental arm was stratified by MCS participation history, region and sex.

The mixed-mode approach significantly outperformed the F2F-only method, achieving a response rate of 66.8% compared to 53.5%. The mixed-mode arm had lower refusal (22.2% vs. 32.4%) and non-contact rates (3.3% vs. 5.5%), demonstrating its effectiveness in reaching participants.

The strong performance of the mixed-mode approach in terms of response rates and cost-effectiveness led to its adoption for the full Age 23 Survey. While some mode effects were observed, they were relatively minor and will be addressed in future guidance for analysts. The shift to a mixed-mode strategy represents a cost-effective method to enhance engagement in longitudinal studies. This robust experimental evidence will be invaluable for similar studies facing comparable trade-offs in survey design, providing empirical insights into the advantages and challenges of mixed-mode data collection strategies.

We anticipate substantial insights and notable findings to arise from the rich data collected in the Age 23 Survey once it is deposited at UKDS, following its completion in February 2025.
Exploitation Route The robust evidence from the initial experiment on the optimal data collection mode will be invaluable for similar studies facing comparable trade-offs in survey design, providing empirical insights into the advantages and challenges of mixed-mode data collection strategies.

PI Contribution College for Interdisciplinary Educational Research is an international interdisciplinary network of early career researchers into education. As part of the three years that I am part of their fourth cohort, we agree to form a 'micro group' of scholars to produce research on an interdisciplinary topic. I formed and lead a group to specifically look at the Millennium Cohort Study and we are currently forming our research question and approach.
Collaborator Contribution They have brought ideas and their own knowledge from their relevant disciplines (economics and sociology) and an international perspective on how the Millennium Cohort Study can be applied to their own countries of study.
Impact Outputs are currently in preparation, but are multi-disciplinary (education, psychology, sociology, economics)

Results and Impact The activity consisted of a knowledge exchange collaboration held between 11-17 Nov 2023 between researchers at the UCL Centre for Longitudinal Studies (CLS) and national and international non-academic organisations, including Administrative Data Research UK (ADR UK), UK Statistics Authority (UKSA), National Statistics Institute of Chile (INE) and a Consortium of Chilean Universities. Its aims were twofold. First, to understand the challenges public organisations face in the UK and Chile when translating academic research into improved policy decisions and efficient public services. Second, to maximise the global reach of the research conducted by the Centre for Longitudinal Studies on administrative data linked to UK longitudinal population studies and its influence internationally. Most of the highlights of the project concentrated around the week when a Chilean delegation visited the UK and participated in several activities. First, a workshop was held at Administrative Data Research UK (ADR UK) facilities with people from ADR UK and the Office for National Statistics (ONS) that lasted a whole day. Second, the participation over three days at the ADR UK Conference in Birmingham, including side meetings with relevant stakeholders for the project. Third, the workshop held at the Centre for Longitudinal Studies (CLS) including researchers from CLS, members of the Chilean delegation, researchers from the Centre for Education Policy and Equalising Opportunities (CEPEO), Department for Education (DfE), University College London (UCL), University of the West of England (UWE), among others.

The project has been useful in shaping the discussion around the Integrated Data Infrastructure that is intended to be implemented in the Chilean case, allowing the United Kingdom experience to influence the direction in which the structure of the system is thought, rescuing the most valuable characteristics of it which seem applicable in the Chilean context.
It also proved helpful for UK authorities from different institutions (ADR UK, ONS, DfE, CLS, etc.), as they were able to question some of the culturally rooted characteristics of the system that they usually do not have the opportunity to analyse retrospectively.

The project also generated some specific and useful inputs for future steps into the agenda to develop an Integrated Data Infrastructure, including:
• A working paper/policy brief synthesising key elements learned from the Chilean delegation visit and the activities held during those days, and further meetings sustained afterwards in the same context.
• A budget proposal for the implementation of an Integrated Data Infrastructure in Chile following a similar structure to the one present in the British case.
Finally, a new partnership was developed through the project. The new partner was the Integrated Data Infrastructure Consortium from Chile, which was formed by five research centres from four Chilean universities. Three members of the Consortium participated as members of the Chilean delegation that visited the UK for five days and participated in all the activities organised in the context of the project.

Results and Impact In June 2023 we celebrated 21 years of the Millennium Cohort Study (MCS) and other longitudinal studies with a two day scientific conference in London. The programme featured an exciting line up of around 75 inter-disciplinary presentations and over 150 attendees. Presenters mainly discussed their research findings using MCS data, however we also heard from researchers who have looked at data from other longitudinal studies of the same era. To encourage participation from early career researchers, they were offered free attendance. We also had a small number of sixth form students attend as part of a widening participation programme that CLS was organising.

There was a very special panel discussion with seven members of the cohort from across the UK. They talked openly about their participation in the study and the audience got to see study members in-person, a very rare and invaluable opportunity for researchers.
