Sources: Employment and businesses
Statistics on employment are obtained from:
- Annual Business Inquiry (Office for National Statistics) - an annual survey of UK businesses, and
- Forest Employment Survey - a Forestry Commission survey of forestry and primary wood processing businesses in Great Britain, last run in 1998/9.
Numbers of businesses are estimated from:
- Industry surveys (Sawmill Survey, Survey of Round Fencing Manufacturers) and industry associations (UK Forest Products Association, Wood Panel Industries Federation) - for businesses believed to be using UK roundwood, and
- Business Start-ups and closures: VAT registrations and de-registrations (Department for Business Enterprise and Regulatory Reform) - for VAT-registered businesses.
The Annual Business Inquiry and Department for Business Enterprise and Regulatory Reform both classify businesses by Standard Industrial Classification (SIC) code. Businesses are classified to SIC codes according to their main activity.
