New CeLSIUS Research Brief: Windrush migrants in the LS (PDF)

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.

July 2018

CeLSIUS is currently operating at a reduced service level due to new staff training: please be aware that there usually will only be one trained user support officer per day available in the ONS office from now until the autumn this year. We must therefore ask for your patience during this time as  work will inevitably be slower during this period.

Presentations and practicals materials now available from 'A showcase of student research using the ONS LS and census microdata', held on 28th March 2018

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
