The indicator is calculated as gross yield per working hour for full-time/ part-time agricultural farms. The source is the agricultural accounts statistics, tables JORD1, JORD2 and JORD3 in Statbank Denmark. The accounts statistics include farms with either at least 10.0 ha or at least 15,000 euros in standard output. Full-time farms have a working time of at least 1,665 hours per year, while other farms are considered part-time. The figures are calculated at fixed prices, using the deflator of agricultural output from the table NABP69 in Statbank Denmark. The indicator is visualized as both gross yield per working hour in fixed prices and as volume index with 2010 = 100. This calculation does not follow the UN definition, which requires a focus at the smallest 40 percent agricultural farms based on crop and livestock information. Although these farms can be found in the integrated farm structure survey (IFS), the problem is that there are no information on production in this survey. The agricultural accounts statistics is the only source with both a size measure - full-time / part-time - and a measure of productivity in terms of gross yields and working hours. This problem is foreseen by the UN: “A major limitation is data availability. In reality, surveys gathering all the required information simultaneously at the farm level are very few. The most appropriate data source for collecting information on total volume of agricultural production and labor input adopted on the agricultural holding would be agricultural surveys. However, in many countries, especially in a developing context, agricultural surveys are rarely conducted.” It is not possible to take forestry into account and fisheries are also not included, as the UN definition describes the extent of agricultural production from small food producers within the areas of crops, livestock, fisheries and forestry. It is not possible to disaggregate the indicator by sex and type of enterprise.
