Table 8 Raising and adjustment factors for arable holdings
| Region | Size Group (ha) | Adjustment factor | ||||
|---|---|---|---|---|---|---|
| 0-19.9 | 20-49.9 | 50-99.9 | 100-149.9 | 150 + | ||
| Caithness & Orkney and Highlands & Islands | 193.00 | 43.67 | 17.33 | 13.00 | 2.00 | 1.0000 |
| Moray Firth | 187.50 | 61.00 | 26.00 | 19.50 | 9.38 | 1.0000 |
| Aberdeen | 177.60 | 50.00 | 26.94 | 12.77 | 9.00 | 1.0000 |
| Angus | 144.00 | 60.80 | 28.82 | 18.11 | 9.16 | 1.0000 |
| East Fife & Lothian | 0.00 | 58.72 | 50.79 | 18.41 | 17.78 | 1.2696 |
| Central Lowlands | 287.00 | 47.71 | 22.00 | 20.67 | 6.10 | 1.0000 |
| Solway, Southern Uplands & Tweed Valley | 515.00 | 49.00 | 36.60 | 19.50 | 11.92 | 1.0000 |
Note: The sampled data within a region and size group were multiplied by the appropriate raising and adjustment factors to create an estimate of national use (please refer to Appendix 5 for description of statistical estimation process). For example, a total recorded rodenticide use of 10 kg on 100-149.9 ha sized farms in Aberdeen would be multiplied by 12.77 (raising factor) and 1.00 (adjustment factor) to give an estimated rodenticide use in that region and size group of 127.7 kg
