Annex I: Meta Data Analysis

This section meets objective ii: To quantify the level of duplication in data collection between the JAC and SAF.

Introduction

Some of the most thorny and potentially disruptive issues that arise in comparing datasets are in ensuring that there are clear definitions of what the data means. This requires the preliminary analysis of "meta-data", that is data about the data. Since the intention is to assess the fitness of data collected in the SAF as an alternative to the JAC censuses then it is essential to have agreed definitions for classes within both datasets and agreed mappings between individual classes or groups of classes. Simple cases such as does "wheat" mean both the winter and spring crop are easily resolved but other definitions such as "other vegetables" or even "other land" can require considerable care if errors are not to be introduced. To this end the project team have developed a combined data dictionary and mapping of categories or groups of categories between which legitimate comparisons can me made.

Materials and Methods

For each question on the JAC form (and thus each JAC variable) the equivalent data requested in the SAF, and held in the SIACS database, have been identified and tabulated. The most up-to-date JAC and SAF forms available in January 2008 have been used. These are: June 2007 main census, June 2007 minor census, December 2007 (winter) survey and May 2007 Single Application Form ( SAF) including field data sheets ( FDS). The land uses recorded via the SAF/ FDS are coded as specified in Annex 2 of the SAF Explanatory notes 13.

The tabulations in the following sections list the data collected in the JAC and present the SAF data that most closely matches. The tabulation also comments on the adequacy of the matching and notes any potential issues. There are some unresolved issues relating to the detailed definitions in Annex 1. If necessary, these will be considered further by the client.

The annex provides a separate table for each Section of the JAC. The rows of each table are the JAC questions. The first three columns in each table indicate whether a question is asked in the main (M), minor (m) and/or December (D) forms. The fourth column shows the item ID for each answer - this is important when referencing the JAC data-sets because they are identified only by item numbers in the supplied data. The next column ' JAC Question/Variable' gives the question from the census forms - on occasion these questions have been reordered or modified slightly in order to keep the tables as compact and concise as possible. The column following this indicates the unit used for the question. The column ' SAF Question/Variable' is used to indicate similar question(s) from the SAF and/or FDS and the 'Notes' as indicated previously reports the adequacy of the mapping and remaining issues. The adequacy of the mapping is presented using the terms in the table below.

Adequacy of JAC to SAF mappings

Partial

SAF partially satisfies the requirements of the JAC

Full

SAF fully satisfies the requirements of the JAC

Compound Partial

SAF partially satisfies a group of JAC requirements but not individual questions

Compound Full

SAF fully satisfies a group of JAC requirements but not individual questions

JAC questions that appear in italics are those that only appear on the minor census. No match up has been shown for these since they are used to 'back calculate' the figures for the associated questions from the main census, e.g. in the Crops section the minor question 0378 (potatoes) is used to 'back calculate' the more detailed main census questions numbered 0024, 0025, 0026 (seed and ware potatoes) using a proportioning method. There is no need therefore to establish equivalent categories within the SAF since the comparison between JAC and SAF will be on the basis of the combined main and minor census or the (winter) survey.

The JAC form is issued with pre-populated area figures, sourced from the CDM14. The information in the CDM is updated using Land and Business Change Form ( LBCF).

Figures in this section of the census form may not agree with the previous one, where changes are still to be notified to area office or a change took place after the forms were sent to the printers.

As above, these questions are not explicitly covered in SAF. It may be possible to provide values based on data held elsewhere within the CDM (e.g. the Field Maintenance Register ( FMR)).

The questions and codes used in the following tables are based on the 2007 December Census. The specific questions in the December Census alternate on a biannual basis so some of the questions and codes are not illustrated below. Since no machinery details are currently recorded in the SAF there is currently no potential to derive values for JAC questions from SAF data.

Generic Issues

  • Land use information within the FDS of the SAF is collected on a per field basis rather than per holding in JAC so holding by holding comparisons require aggregation of FDS/ SAF fields to the holding level. These fields to holdings relationships are held within the SIACS database.
  • Consideration will also be given to the fact that the same questions might be asked but at different times of the year - for instance the SAF considers animal numbers as at 1st March while the census is as at 1st June.
  • It can, in some circumstances, be ambiguous for claimants which SAF code is most appropriate for the land use. For example, 'bedding and pot plants grown in the open' could be claimed under 'bulbs/flowers' ( BFLO) or perhaps even 'trees, shrubs and bushes' ( TSB). In this case the error would not be significant for the calculation of payments (?) since both are ineligible land uses. Errors within eligible categories with same payment regime are similarly insignificant for payment. In both cases, however, these errors may result in differences with the JAC.
  • Energy cropping - biomass, short rotation coppice etc. Some non-food activity can be carried out on set aside land (including energy cropping e.g. oil seed rape for industrial use, short rotation coppice, etc). If this is the case, should that area be recorded under JAC item 0003 and nowhere else to keep the area totals consistent? (It may help to note that where crops fall under the ECS this isn't an issue, as areas subject to an application for ECS may not be counted as being set aside).
