Working papers

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.

Assessing recall of early life cicumstances- CLS working paper 2012/3

Author: Matt Brown

This CLS working paper uses data from the 1958 National Child Development Study (NCDS) to assess recall of early life circumstances. The report examines responses to questions about childhood experiences that were answered when cohort members were aged 50.

These questions re-collected information that was first collected contemporaneously. The paper will assess the accuracy with which individuals can recall these details some 40 years later by comparing the information reported at age 50 with the data captured at age 11.

Child development

Unequal entry to motherhood and unequal outcomes for children- CLS working paper 2011/3

Author: Denise Hawkes, Heather Joshi

The age of mothers when they give birth to their first child is increasingly socially polarised in the UK. Early motherhood typically occurs among women from disadvantaged backgrounds, in contrast to women with later first births, who are more likely to come from advantaged backgrounds. This CLS working paper compares their children’s development, in terms of cognition and behaviour at age five, using the Millennium Cohort Study (MCS).
