Webinar: Education in the long run - which data are available? Held on 2 April 2019

The session will explore:

  • The range of longitudinal data on education available from the UK Data Service, including harmonised data, such as ‘Understanding Society: Waves 1-8, 2009-2017' and 'Harmonised BHPS: Waves 1-18, 1991-2009‘
  • The ONS Longitudinal Study, including the data structure, available research topics (with a focus on education) and procedures for access. Some results will be  presented on how education relates to economic activity status through the life-course in a historical sample of young men and women
  • The value of using of longitudinal data for educational research purposes: case studies

Webinar: An update on ONS's plans to transform the population and migration statistics system, held on 7 March 2019

Jointly organised by CeLSIUS and the UK Data Service. Administrative data are a rich source of data and have the potential to transform the way in which we gather demographic data. In this webinar, hosted by the UK Data Service, Becky Tinsley, ONS's Head of Admin Data Census, and Becca Briggs, from ONS's Migration Statistics Division, will outline the background to the Administrative Data Census project and focus on the recent publication updating on the journey to transform the population and migration statistics system, and the ambition to put admin data at its core.

ONS in Pimlico safe setting reminder

Please note that to contact the CeLSIUS team when using LS data in ONS London, you need to phone 020 7592 8632 (8632 internally) or one of the other numbers displayed on the safe setting wall.

CeLSIUS estimate that in 2011 there were around 1,735 Windrush children who had entered the country prior to 1971 - find out more about how the ONS LS can be used to estimate the number of Windrush migrants in ways which go beyond the methods based solely on the most recent census, or on the Labour Force Survey.

Recent changes to ONS LS output clearance procedures:

LS users may have received several emails from CeLSIUS/the ONS relating to changes to clearance procedures - please note that the following are the only changes that have occurred recently:

  • 'Pre-publication' clearance will replace 'Intermediate Outputs'.
  • ‘Publication' clearance will replace 'Final Outputs'.
  • BOTH procedures will require results to be aggregated to the same minimum cell threshold. That is, in results from which a count of individual persons could possibly be calculated - e.g. percentages, or graphs based on percentages - the cell count will be 10 or more.
  • However, both types of clearance may be possible for results which do not meet this criterion if there is a scientific justification, i.e. both a reason why clearance of lower cell counts is needed, and a persuasive argument that in this case they could not lead to disclosure.
  • Publication and Pre-publication clearances will involve two members of staff.
  • LS users working overseas will be dealt with on the same basis as those based in the UK.

Please also note that CeLSIUS support officers will continue to:

  • do pre-publication clearance on log files and other formats
  • run code for users and send out the cleared outputs (subject to the conditions outlined above)
  • alter users' outputs where necessary to make them clearable
