A common indicator to describe farm structure is the farm size, though it can refer to various measures, such as land area, economic outcomes, or farm labour. The FSS data indicate that two thirds of the 10 million EU farms have less than five hectares of land and the majority of these farms do not exceed two hectares (see figure to the right). Also, more than two thirds of EU farms have a total standard output (i.e. an estimate of the average farm output based on standard values) of below €8 000 a year. EU farms count on average less than one annual work unit (i.e. the equivalent of a full-time job). Indeed, while about 20 million people work on EU farms, this figure includes full- and part-time farm managers and workers, seasonal labour, and farmer’s family members providing help (often free labour) when needed.
