purview (noun) 

Purview (PUR-vyoo) is the range or limit of authority, competence, responsibility, concern, or intentions. As used by Uzodinma Iweala: “Around the world, our cities are not the idealized open, accessible, and cosmopolitan spaces of our dreams. More often than not, they are sectioned and controlled purviews of the radically wealthy, surrounded by clusters of have-nots.”
