Survey of Round Fencing Manufacturers
Introduction
The Survey of Round Fencing Manufacturers is an annual survey conducted by the Forestry Commission (in association with the Forest Service) of round fencing manufacturers (or mills) in the UK that are believed to consume UK-grown roundwood.
The survey, which previously covered mills in Great Britain only, was extended in 2004 to include those in Northern Ireland. Figures for Northern Ireland in earlier years have therefore been estimated, based on responses to the 2004 survey.
Figures are published as UK totals and by size of mill.
Longer time series, providing data on numbers of mills and on softwood consumption are available at www.forestresearch.gov.uk/tools-and-resources/statistics/data-downloads/. The time series data feature breakdowns by size of mill and by country.
Data collected
The questionnaire used for the Survey of Round Fencing Manufacturers is issued to around 60 mills, to collect information on the consumption of UK-grown and (from 2006) imported roundwood. In 2008, the survey was extended to cover woodfuel quantities (sales to bioenergy, sales as firewood and internal use for heat/ energy) and total employment. In 2010, the survey was further extended to request data on production of round fencing and other products. A breakdown of the country of origin (England, Wales, Scotland, Northern Ireland) for UK-grown roundwood is also requested.
More information on the Survey of Round Fencing Manufacturers, including copies of the questionnaires sent to businesses in recent years, can be found at Surveys – Forest Research.
Response rates
The questionnaire was issued to 53 mills for the collection of 2017 data, of which 21 responded, giving a response rate of 40%. These respondents accounted for an estimated 36% of roundwood purchased by softwood round fencing manufacturers.
Survey of Round Fencing Manufacturers Response Rates, 2008-2017
| Year | Forms issued | Responses received | Response rate1 | Weighed response rate2 |
| 2008 | 87 | 55 | 63% | 88% |
| 2009 | 82 | 42 | 51% | 56% |
| 2010 | 79 | 34 | 43% | 46% |
| 2011 | 72 | 26 | 36% | 58% |
| 2012 | 68 | 26 | 38% | 53% |
| 2013 | 67 | 27 | 40% | 51% |
| 2014 | 62 | 26 | 42% | 42% |
| 2015 | 60 | 29 | 48% | 54% |
| 2016 | 55 | 23 | 42% | 49% |
| 2017 | 53 | 21 | 40% | 36% |
Notes:
1. Response rates are calculated as the number of responses received divided by the number of forms issued.
2. Weighted response rates have been calculated from the 2008 survey onwards. They are an estimate of the proportion of total roundwood purchased by softwood round fencing manufacturers that is accounted for by respondents.
Methodology
Each year, figures for non respondents are estimated by rolling forward data from previous years for these mills.
Quality
Detailed information on the survey quality is provided in the “Quality Report: Survey of Round Fencing Manufacturers”, available at www.forestresearch.gov.uk/tools-and-resources/statistics/about-our-statistics/code-of-practice/quality-of-official-statistics/.
Further quality information on FC Official Statistics is available at: www.forestresearch.gov.uk/tools-and-resources/statistics/about-our-statistics/code-of-practice/quality-of-official-statistics/.
Revisions
Results from the Survey of Round Fencing Manufacturers may be revised between the provisional figures published in the First Release “UK Wood Production and Trade: provisional figures” and the final data published in “Forestry Facts & Figures” and “Forestry Statistics” to take account of late returns and the results of additional data quality checking procedures.
All figures are subject to revision annually, as information becomes available about mills opening or closing, or new information becomes available for previous non-respondents. Such revisions are generally quite small.
Figures for 2017 are final; provisional figures were previously released in “UK Wood Production and Trade: 2017 provisional figures”. Figures for 2017 and earlier years have not been revised from those in “UK Wood Production and Trade: 2017 provisional figures”. Information on revisions made since “Forestry Statistics 2017” are provided in “UK Wood Production and Trade: 2017 provisional figures”.
Release schedule
Provisional figures for 2018 will be released on 16 May 2019 in “UK Wood Production and Trade: 2018 provisional figures”.
Final figures for 2018 will be released on 26 September 2019 in “Forestry Statistics 2019” and “Forestry Facts & Figures 2019”.
