The study aims to carry out an analysis from demographic perspective for the city of Arad during the years 1767-1768. It is based on two documents that contain mainly statistical data with which it is possible to emphasize aspects related to some demographical behaviour in Arad. Information about the deceased, newborns and marriages registered, about the share of different ethnicities and confessions help us to outline the image of Arad, in which, during the XVIIIth century has been seen a clear process of modernization and demographic growth.
