This dataset provides estimates of employee jobs in London down to 4-digit Standard Industry Classification level, from 1998 to 2015. Data are based on Business Register and Employment Survey (BRES) and Annual Business Inquiry part 1 (ABI/1) published by the Office for National Statistics (ONS), as at June 2017. Data covering workforce jobs data series are based on workforce jobs published by the ONS, as at June 2017. In order to produce a consistent time series using the official business survey and workforce jobs data, some modelling has been necessary. The underlying assumptions are outlined in the methodology paper published alongside these data tables. Note that the 2014 and 2015 updates were republished (in March 2018) following additional disclosure checking.
