The objective of the research is to understand the characteristics and the motivations of a sample of volunteers, based on the data of the World Value Survey, which have been recently made available. The tools of AI will permit to handle a very large data-set, across many rich, middle income and an poor countries. In the following sections a brief review of the literature and the most recent empirical evidence on volunteers’ supply and demand will be presented (Sect. 2). In Sect. 3 data and methodology will be introduced. Section 4 contains the results of the analysis. Section 5 will conclude.
