The statistical surveys have used different bins over the years to report numbers of farms and total space used over the years. These bins have been manually unified. A few errors in the Excel file were corrected manually. This was the case for some totals (minor inconsistencies). Also inconsistent were the use of number formatting and actual numerical values included in the table. Some cells contain absolute values and use Excel’s number format to display 1000s ha, others contain the 1000s ha as the value itself.
