The aim of the paper was to identify different levels of social sustainability in farms of various production types (8 types) in EU countries. The study is based on the Sustainable Value (SV) method, which is value-oriented, measured as the sustainability of agriculture at the microeconomic level (e.g. agricultural farm). To be able to compare farms among themselves, an RTC was calculated. The FADN database for the years 2004-2015 was used in the article, analyzing four types of farms (field-crop, horticulture, milk and granivores). It was indicated that what was most important for social sustainability was the relation between the employed labour input, especially own, family labour input, and the achieved effects in the form of total output value, but first of all, income from the family farm (farm net income).
