In this paper an attempt to verify, whether the empirical data confirm the welfare determinants suggested in economic literature, like e.g. educational, geographical, behavioural features of the individual and his/her parents, see e.g. Wedgwood (1928). The analysis is conducted using machine learning tools and then the obtained results are compared with other studies. To ensure the possibility of such assessment the capability of interpretation in terms of natural language is needed and thus the knowledge in the form of classification rules is presented.
