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.
