1. Improvements to the BRES
The Business Register and Employment Survey (BRES) now allows greater access to industry and geographic detail than was previously available. BRES is the major industrial survey that is the primary source for job counts between 2008 and 2011. For previous releases, we only had access to the data published by the ONS on their website, which was limited in industry and geographic detail. As of January 2013, the BRES data available to us covers all NUTS 3 regions (Counties and Unitary Authorities) and 5-digit SIC 2007 industries. With the increase in the detail of the data available, 2008-2011 industry data will have improved accuracy at detailed regional levels.
2. Revisions to Staffing Pattern
We have also included revisions to how industries are ‘staffed’ into occupations. Previously, EMSI only utilised primary industry and occupation job descriptions from the Labour Force Survey microdata for determining industry by occupation data. The 2013 run incorporates second jobs reported to the Labour Force Survey as well, which will increase the representation of many jobs that are typically part-time (such as bar staff and cleaning occupations). The result of these two changes should be seen in an increased reliability of historic industry data and an increased representation of second jobs in the data.
Demographic data has not been updated in this release, since Census 2011 data necessary for updating race and ethnicity estimates will not be released until the second quarter of 2013. EMSI will update the demographic data in Analyst as soon as these estimates become available.
Variations in Data
Users of the tool may notice certain variations between the 2012.1 Class of Worker dataset and the 2013.1 BETA set that we have just released. These variations are due to changes in our data sources (published by the Office for National Statistics) and come primarily from a shift in how the BRES is conducted. The BRES has revised its classification system for working owners and reclassified a large number of workers from self-employed to employees, which has caused the reported employee numbers to increase by about 500,000 jobs.
