A data set containing information on the explicit connections concerning all members of Portuguese governments from 1976 until July 2013 is presented. This information was collected through a one-year research carried out by the authors using public records and official information (public and private institutions). The data set was collected during the process of elaborating a book [1]. This database is the first open-access source of information on a specific type of community which enables a wide range of research in areas such as social and political sciences and economics.
