Results from the June 2016 Scottish Agriculture Census

4. Notes

4.1 Background

This publication contains final results for the 2016 June Agricultural census and trends over the last ten years.

4.2 Uses of the information

The census is conducted for a wide range of purposes. The statistics help the government to form, monitor and evaluate policy, and to assess the economic well-being of the different agricultural sectors. Most of the data collected is required by the Statistical Office of the European Communities. Equally important is the regular contact with farmers, which enables the department's register to be kept up to date. This means, for example, that information on new animal health requirements, or new subsidy schemes can be quickly directed to relevant farmers.

Most of the data collected are required by the Statistical Office of the European Communities, specifically Council Regulation 1165/2008 which sets out requirements for provision of cattle, pig, sheep and goat statistics in both May/June and November/December. It defines the category, age or weight of livestock for which statistics are to be provided and specifies the provision of quarter-year and half-year production forecasts. There is also a separate EC Regulation covering the submission of winter crops. This information is collated by the Department for Environmental and Rural Affairs (Defra) for submission at member state ( UK) level.

Some examples detailing how the census data are or have been used:

• to estimate the total income from farming, as part of the Scottish GDP figures and to compile the National Accounts for the UK.
• to model various scenarios/options and analyse outcomes/impacts on Scottish agriculture in relation to a range of options on the future of support for Scottish Agriculture.
• to provide disease and epidemiology modellers with a snap-shot of livestock numbers and locations (at 1st June) to assist with real-time and emergency planning procedures for animal disease outbreaks.
• UK ammonia and greenhouse gas inventories - the census provides Scottish agricultural land and livestock data.
• to support work on various research packages such as assessing the potential impact of CAP (Common Agricultural Policy) reform on payments to farmers; early environment effects on animal health and welfare; assessing the effectiveness of measures to manage water quality and control diffuse water pollution.

The census is also used by the main research providers working for the Scottish Government on numerous projects and underpins the majority of the analysis and research that is carried out, and to provide sampling frames for this research. In some cases it is also used to identify holdings for receipt of important and relevant information by mail, subject to the terms of Section 80 of the Agriculture Act 1947 [9] .

4.3 June Census outputs

Results from the June census are available to the public as follows:

The Annual Abstract of Statistics presents a time series from 1982 onwards which also contains some additional detail on selected items (common grazing, land tenure etc.). It is available to download as a spreadsheet along with this publication and can be accessed here:
http://www.gov.scot/Topics/Statistics/Browse/Agriculture-Fisheries/PubAbstract/AbstractPub

Previous editions of the Abstract can be accessed here:
www.gov.scot/Topics/Statistics/Browse/Agriculture-Fisheries/PubAbstract

The outputs from the census on livestock and crops are also used as key inputs to the Total Income from Farming ( TIFF) model, which is used to estimate the value of agricultural productivity in Scotland. Headline results are published each January with more detailed analysis presented in the Economic Report on Scottish Agriculture ( ERSA), which is published in May or June of each year. Results for TIFF can be accessed as follows:
www.gov.scot/Topics/Statistics/Browse/Agriculture-Fisheries/ResultsTIFFFBI

The Economic Report on Scottish Agriculture ( ERSA) is a compendium publication which contains detailed statistics on Scottish agriculture. It contains three sections covering, (i) Total Income From Farming ( TIFF - see above for more details), (ii) Farm Accounts analysis (income and expenditure statistics by different farm types) and (iii) additional statistics/analysis from the June census e.g. more detail is provided on the structure and composition of Scottish agriculture in terms of the types of activity on holdings, additional geographic analysis is provided along with some UK comparisons.

EC regulations

The EC demands that each member state collect agricultural statistics every year, enforced through a number of EC regulations relating primarily to crops and livestock. Specific regulations are listed on pages 11 to 13 of our 2013/14 annual statistics plan; a link is provided here:
www.gov.scot/Topics/Statistics/Browse/Agriculture-Fisheries/scotstat/planning

These regulations are legally enforceable by the EC, meaning that member states must comply with the data collection requirements in order to avoid financial penalties. In Scotland, the June census is the main survey that is used to meet these requirements as part of providing a response to the EC at a UK level.

We also use the June census to contribute to the formulation and publication of UK statistics on agriculture. These publications are co-ordinated by Defra and more details are available here:
www.gov.uk/government/publications?departments%5B%5D=department-for-environment-food-rural-affairs&publication_filter_option=statistics

4.4 Data collection

The June Agricultural Census is conducted annually by the Scottish Government's Rural and Environmental Science Analytical Services division ( RESAS). Data are requested from all holdings who submitted a Single Application Form ( SAF) in the previous year, together with some other large businesses that would not be eligible for support payments. A sample of holdings which didn't submit a SAF or who didn't return a form last year were also sent a census form.

Data for the June census is collected from three sources:

• Land data were extracted from the Single Application Form ( SAF) database for around 23,700 holdings that are claiming Basic Payment ( BP). Holdings that submitted a SAF in 2015 were also sent a cut-down census form (23,400 forms) to collect the additional data on livestock and labour. See section 4.7 for more details on the use of SAF data.
• From the remaining holdings that did not complete a SAF in 2015, 8,200 (potentially including holdings that submitted a SAF for the first time in 2016) were sent a full census form covering land, livestock and labour.
• All cattle data (including data on cattle breeds) were collected from the Cattle Tracing Scheme administrative source. This means that we effectively have 100 per cent coverage, even for those smaller holdings that were not selected for inclusion in the census.
• The following table gives a breakdown for forms returned for each category of holding.
• Land-use data was received for holdings covering 90 per cent of the total agricultural area, either from returned full census forms or the SAF (shaded grey).
• Cattle data was received for 100 per cent of holdings with cattle, from the CTS.
• Other data was received for holdings covering 67 per cent of the total agricultural area, from returned census forms (the final column in the table).

Census type (1)		Total number	Number selected (2)	Number of returns (3)	Total area	Area of selected (2)	Area of returns (3
SAF		23,683	23,027	16,567	4,900,309	4,853,166	3,492,922
	full form		509	290		90,839	60,138
	part form		22,518	16,277		4,762,327	3,432,784
Non-SAF		28,213	8,533	4,407	751,843	494,870	297,117
	full form		7,631	3,896		386,739	224,459
	part form		916	523		108,131	72,658
Total		51,896	31,574	20,975	5,652,152	5,348,036	3,790,039

(1) " SAF" refers to holdings where land-use data is available from the Single Application Form dataset.
"Non-SAF" refers to holdings where land-use data is only available through the June Agricultural Census form (if at all).
"full form" refers to the long version of the census form covering land use, livestock (except cattle), and labour, designed for those not completing the SAF.
"part form" refers to the short version of the census form covering livestock (except cattle), and labour, designed for those known to be completing the SAF.
(2) The numbers selected are slightly lower than the total number eventually identified due to annual changes in the list of holdings.
(3) The return numbers quoted here relate to the number of survey forms received. For SAF holdings this masks the fact that we effectively receive 100 per cent response for all land items. Cattle data, from the CTS database, is also effectively 100 per cent complete. Response rates based on these figures therefore relate to other livestock and employment data.

4.5 Treatment of non-response

In Scotland the registered details of the 51,896 agricultural holdings are used to maintain a holding-level dataset of agriculture for statistical purposes. This provides a virtually complete coverage of agricultural activity in Scotland. However, please note that:

• we do not conduct a full census as this would place an unnecessary burden on farmers.
• for the selected holdings that are surveyed, not all farmers return data to us.
• gaps in our holding-level data set are 'maintained' by producing estimates.

Estimates are produced for holdings which were (i) not surveyed and (ii) surveyed but did not provide a response, either to the whole form or to certain questions. Holdings are divided into strata (using farm type and 'economic' size) and estimates are made (using ratio estimation) for non-responders within each separate stratum. Estimates are restricted to a maximum of +/-2.5% change on the previous year for each holding, in order to avoid artificial distortion in the overall statistics. Artificial distortion can occur when large actual changes in a small number of holdings within a stratum are applied to non-response holdings in the same stratum.

Within each stratum, land, livestock and labour values for non-response holdings are calculated by looking at those holdings that returned data in 2016 and calculating the percentage change since their previous census responses. These percentages are applied to the non-responders' previous data for the corresponding years. That is, if a given non-responder last returned data in 2008, the percentage change for holdings returning data in both 2008 and 2016 is calculated, and this is applied to the 2008 data for the non-responder to give an estimate for 2016. Labour figures are rolled forward using the most recently returned data.

These changes in the method of imputation were introduced for the 2014 Census. More information on these changes can be found in that year's publication. [10]

Since 2014, data have been collected for beehives and blueberries. Where a census hasn't been returned in 2014 or 2015, figures for blueberries were imputed based on past responses for mixed and other fruit before relative proportions based on actual responses were used to calculate the final figures for blueberries and mixed/other fruit.

Note, however, that trend information is limited only to the previous year for beehives and donkeys, which were first specifically collected in 2015. Consequently, alongside the figures for actual responses, we have provided an estimate, based on actual returns within each stratum (based on size and type), to account for non-response and for holdings which were not sampled.

4.6 Data quality

Relevance

The content of the census and any changes to it are agreed with a range of Scottish Government divisions and, where necessary, the Scotstat network. The survey provides data used by both the Scottish Government and the EU to assess agricultural activity, in the monitoring and development of policy (see section 4.2 above).

Accuracy

Data undergo several validation processes as follows; (i) checking for any obvious errors on the paper census forms upon receipt, (ii) auto-checking and identifying any internal inconsistencies once loaded onto the initial database, (iii) auto-checking for any sudden changes in comparison with previous annual returns and other holdings (iv) assessing any trends or switches in item areas or quantities that look unreasonable.

If necessary farmers are contacted to ensure data are correct. Additional quality assurance is provided at the later stages by utilising expert knowledge within the Scottish Government and the agriculture industry.

See sections 4.4 and 4.5 for further information on survey methodology.

Timeliness and Punctuality

Results have been published about five months after the census date. The census date was set at 1st June 2016, with returns requested by 15th June. However, forms were still being received throughout September, when the census was then closed to finalise results. Forms received after closure of the census are used for imputation of the following year's census, and will be incorporated into revisions published alongside the results of the June 2017 census.

Accessibility and Clarity

These statistics are made available online at the Scottish Government's statistics website in accessible formats (html and pdf versions are available). All data tables are made available in Excel format to allow users to carry out further analysis. We encourage feedback on the content and format of our publications.

Comparability

The publication includes comparable data from the previous ten years' censuses, with data from years prior to that published in the accompanying abstract.

The change to collecting some administrative data via the Single Application Form led to some apparent discontinuities in the data between 2008 and 2009. Likewise a change in the collection of data on strawberries and raspberries has led to some discontinuities between 2010 and 2011 and between 2011 and 2012 (see section 4.7). Further changes to data collection in 2015 led to discontinuities in grass, rough grazing, woodland, other land between 2014 and 2015 and also led to the non-availability of seasonally let land in 2015 (see section 4.7).

Use of data from the Cattle Tracing Scheme means that cattle data prior to 2006 are not directly comparable, though they have been scaled up by about three per cent where comparison is necessary.

4.7 Use of administrative data from the Single Application Form

Since 2009, data on land use has been obtained from the Single Application Form ( SAF). These data were combined with land use data from all the other holdings, collected through June Census forms, to generate overall June Census results. This development led to a substantial reduction in statistical data collection and an overall improvement in the quality of land use statistics. In 2015 SAF data was obtained for 23,800 agricultural holdings.

While the method of incorporating SAF data is believed to be more accurate than the previous method, it resulted in a step change in some of the land use results for 2009, especially for rough grazing and grass. This meant that changes between 2008 and 2009 for these land use categories did not represent genuine changes in land use, but rather differences in the way this data had been reported. These should therefore be treated with caution.

In 2015 the definitions of temporary and permanent grass were changed on the SAF. From 2015, temporary grass relates to whether it has been reseeded in the last five years, whereas previously it related to how long it had been used for grass. The new definition only includes land that is included in a holding's crop rotation. This means changes between 2014 and 2015 in grass under 5 years old, and grass 5 years and older do not represent genuine changes in land use, but instead differences in how grass data were recorded.

Changes made in 2015 to the ways in which rough grazing, woodland, other land and seasonally let land were collected on the SAF have carried forward to this year. This has affected the level of detail available in these land use categories for some holdings while data on seasonally let land data could not be collected. Consequently, for SAF holdings, about 534,000 hectares of rough grazing, woodland and other land data had to be imputed (nine per cent of the total agricultural area). This included 26,000 hectares of rough grazing (one per cent), 375,000 hectares of woodland (75 per cent) and 133,000 hectares of other land (86 per cent).

The imputation was based on the results for the holding from previous years, as well as the results from similar holdings in the current year. The increase in the amount of imputation means that the results are less precise than was the case in 2014. However we believe the accuracy of the data is still higher than with the method used prior to the introduction of SAF data in 2009.

4.8 Collection of cattle data through the Cattle Tracing Scheme

Statistical data on cattle populations have historically been collected through the June census and December survey in Scotland. In order to reduce the burden on survey respondents, cattle data has been obtained through the Cattle Tracing System ( CTS) since June 2013. CTS, an administrative data source held by the British Cattle Movement Service ( BCMS), records cattle movements across Great Britain and has also been used to obtain cattle figures for England and Wales since 2007.

Usable data from the CTS is only available for Scotland from 2006. For comparability, tables containing data collected via the survey methods used up until June 2012 have been included. For those years where both census and CTS data are available, CTS data have been, on average, 3.2 per cent higher than that collected through the census.

Further information relating to the collection of CTS data can be found in Annex A of the Economic Report on Scottish Agriculture 2013 [11] .

4.9 Respondent burden

One of the recommendations resulting from the UKSA assessment of Scottish Government agricultural statistics was to report annually on the estimated costs of farmers responding to the agricultural surveys.

To determine how long it took farmers to complete the December survey, around 110 farmers were asked over the telephone for an estimate of the total time it took them to fill in the form itself as well as the time taken to read guidance notes, count livestock or consult business records containing information required to fill in the form etc. More information on how this exercise was conducted can be found in the results from the 2011 December Survey of Main Holdings:
http://www.gov.scot/Publications/2012/03/7513

A median time of 30 minutes was derived from this survey of farmers in December and is the figure used as the baseline for calculating respondent burden for the June Census. Calculations for estimating respondent burden for the June Census are based on the assumption that the partial form completed by those also submitting a Single Application Form ( SAF) takes around the same time to complete as the December Survey form, while the full June Census form takes twice as long.

The table below employs formulae based on guidance given by the Scottish Government Statistics group. It is estimated that farmers spent 12,600 hours completing the June Census forms in 2016 at a cost of £170,000:

Number of responses (partial form)	16,789
Median time taken to respond in hours	0.5
Time taken to respond to partial form in hours	8,395
Number of responses (full form)	4,217
Median time taken to respond in hours	1
Time taken to respond to full form in hours	4,217
Total hours taken to respond to forms	12,612
Hourly rate of typical respondent*	£13.47
Total cost of responding to June Census forms	£169,884

4.10 Revisions

Major revisions to the results from the June Agricultural Census are published on the Scottish Government website:
www.gov.scot/Topics/Statistics/Browse/Agriculture-Fisheries/revisions

4.11 Soft fruit under cover

From 2011 the areas of strawberries and raspberries were collected separately for fruit grown in open fields, under walk-in plastic structures, or in glasshouses. Further details on these changes are described in the 2012 June Agricultural Census. [12]

4.12 Full tenancies and seasonal tenancies

The methodology for calculating holdings with rented land and full tenancy arrangements was refined in 2014. In order to calculate a breakdown of tenancy types and associated areas, in cases of non-response, data from the most recently returned data was used. In addition, information returned in 2014 on holdings for which there was previously no tenancy type information available was applied to data for 2013. Additional information from the Crofting Commission has also been applied to data for 2013 and 2014. Estimates for remaining cases of non-response were calculated by applying proportions from actual responses to those holdings with rented land for which no tenancy type information was available. Further work was carried out in 2015 to validate data on Small Landholder Act Tenancies, which has led to a reduction in the estimated number of holdings.

Due to changes in the Single Application Form, data on seasonal tenancies were not available this year. It is hoped that we will be able to collect data in future years. Data on seasonal tenancies was previously published in ' Tenanted Agricultural Land in Scotland 2014 [13] .

4.13 Farm Types, Standard Outputs and SLRs

Using results from the Census, holdings are classified into farm types, which are allocated based on the main activity on the farm (as defined by the holding's Standard Output value). Since 2015, the farm type breakdown uses price-derived coefficients based on a five year (2010) centred average. More information on farm types can be found in the Economic Report on Scottish Agriculture [14] .

There are eleven basic farm types (cereals, general cropping, horticulture & permanent crops, pigs, poultry, dairy, cattle & sheep ( LFA), lowland ( non-LFA) cattle a& sheep, mixed, forage and unclassified. 'Unclassified' related to holdings with no SO value ( e.g. holdings with fallow land only), whereas 'mixed' is where no single crop or livestock category is dominant.

For 2016, minor changes were made to the way in which holdings were allocated to farm types. These have resulted in 80 holdings shifting from mixed to horticulture and around 900 holdings moving from forage to general cropping.

In addition to the number of holdings and Standard Output values by farm type, table 12 also details Standard Labour Requirement ( SLR) values. SLRs represent the notional amount of labour required by a holding to carry out all of its agricultural activity and is also used as a measure of farm size. Standard Labour Requirements are derived at an aggregate level for each agricultural activity. The total SLR for each farm is calculated by multiplying its crop areas and livestock numbers by the appropriate SLR coefficients and then summing the results for all agricultural activity on that farm. One SLR equates to 1,900 working hours per year.

The SLR coefficients used in this publication have changed this year, and now match those used elsewhere in Great Britain. They have been applied to the 2016 crop areas and livestock units of holdings.

4.14 Other publications

The next large agricultural survey will be the 2016 December survey of agricultural holdings. This is a smaller exercise which surveys around 15,000 of the larger holdings, and, since December 2015, has been combined with the Sheep and Goat Annual Inventory. Results will be published in Spring 2017. Results for the 2017 June census will be published in September/October 2017. The European Farm Structure Survey also took place in 2016, with results scheduled for publication in November 2016.

Statistics on the production of meat, milk, eggs and other livestock products are published in the Economic Report on Scottish Agriculture ( ERSA). These can show different trends in livestock numbers to those shown above, as they are also dependent on factors such as production yields and international trade in livestock for finishing and slaughter. ERSA also provides statistics on the price and value of livestock and other agricultural outputs. These data can be accessed here:
