Abstract copyright UK Data Service and data collection copyright owner.The Cohort and Longitudinal Studies Enhancement Resources (CLOSER) project aims to maximise the use, value and impact of longitudinal research. It brings together leading longitudinal studies, the British Library and the UK Data Service, to stimulate interdisciplinary research, develop shared resources, provide training, and share expertise. Resources available from CLOSER include harmonised datasets (developed to facilitate cross-study comparisons) and CLOSER Discovery (a search engine that enables researchers to search and browse questionnaires and data from different longitudinal studies). CLOSER’s website also includes a range of training materials focused on longitudinal studies and data. CLOSER is funded by the Economic and Social Research Council (ESRC) and is based at the UCL Institute of Education.The CLOSER Work Package 2 provides the harmonisation of socio-economic measures between the National Survey of Health and Development (NSHD), National Child Development Study (NCDS), 1970 British Cohort Study (BCS70), and the Millennium Cohort Study (MCS).Further information can be found on the CLOSER website. The content of longitudinal studies, including questions, topics and variables can be explored via the CLOSER Discovery website.  The Harmonised Socio-Economic Measures in Four Longitudinal Cohort Studies: MRC National Survey of Health and Development: Special Licence Access provides the harmonised socio-economic measures for the NSHD.For the second edition (October 2019), revised data and documentation have been deposited.In June 2022, all cases for two respondents were set to missing at the depositor's request.Main Topics:The main topics covered are:socio-economic measures;occupational classification;social and occupational mobility.
