Introduction
Data sources and methodology
Statistics on employment are obtained from:
Statistics for accidents to employees are obtained from Health & Safety Executive statistics for Great Britain, available at www.hse.gov.uk/statistics.
Numbers of businesses are estimated from:
Standard Industrial Classification (SIC)
The Annual Business Survey (Annual Business Inquiry prior to 2009), statistics on health and safety and statistics on VAT and/or PAYE registrations classify businesses by UK Standard Industrial Classification (SIC) code. Detailed information on the SIC is available at: https://www.ons.gov.uk/methodology/classificationsandstandards/ukstandardindustrialclassificationofeconomicactivities/uksic2007.
Businesses are classified to SIC codes according to their main activity. The SIC codes are revised periodically to take account of changes in the global economy. The following codes from SIC 2003 and SIC 2007 have been used in this edition of Forestry Statistics:
Standard Industrial Classification
Title | SIC 2003 | SIC 2007 |
Forestry | 02 (forestry, logging & related services) | 02 (forestry and logging) |

Pulp, paper & paper products | 21 (manufacture of pulp, paper and paperboard). | 17 (manufacture of paper and paper products) |
Pulp & paper | 21.1 (manufacture of pulp, paper and paper products) | 17.1 (manufacture of pulp, paper and paperboard) |
Articles of paper & paperboard | 21.2 (manufacture of articles of paper and paperboard) | 17.2 (manufacture of articles of paper and paperboard) |
Total wood processing | SIC 20 + SIC 21 | SIC 16 + SIC 17 |
Total primary wood processing | SIC 20.1 + SIC 20.2 + SIC 21.1 | SIC 16.1 + SIC 16.21 + SIC 17.1 |
In addition figure 7.1, covering accidents to employees, also uses the following SIC 2003/2007 codes:
Quality
The forestry and wood processing businesses covered by the Annual Business Survey (Table 7.1), accidents to employees (Table 7.3) and VAT and/or PAYE registered businesses (Table 7.5) differ from those covered by the timber industry surveys and enquiries (Chapter 2, Tables 7.2 and 7.4), as follows:
Reporting requirements for accidents have changed, with absences of at least 3 days to be reported until March 2012 and absences of at least 7 days to be reported from April 2012. As a result, accident data from 2012-13 are not fully consistent with figures for earlier years.
Revisions
Statistics on employment and businesses obtained from others are subject to revision whenever the source data are revised.
Statistics from timber industry surveys and enquiries are subject to revision whenever the timber statistics are revised (see relevant pages within the Sources’ chapter for further information on revisions to industry surveys and enquiries). The revisions made to the sawmill survey and the survey of round fencing manufacturers have resulted in:
The Forestry Commission’s revisions policy sets out how revisions and errors to these statistics are dealt with, and can be found at: www.forestresearch.gov.uk/documents/4355/FCrevisions.pdf.
