PROPHE's geographical scope is global. It aims to be as inclusive as logistics allow. It gathers and welcomes data, laws, and other documents from all countries. It likewise encourages serious research wherever it can. At the same time, in-depth analysis focuses on a selected number of important national cases. Collaborate Scholars are mostly from large countries but Affiliates and others extend PROPHE's scope to other large countries and to smaller ones. “Global” very much encompasses the hugely significant yet highly atypical U.S. case.
