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
