dc.description.abstractEn	In this paper we explain how an arithmetical invariant for G- cover - we call the base invariant - provides a stratiﬁcation of Hurwitz moduli spaces of G-covers of the pro jective line by closed subvarieties. This strati- ﬁcation geometrically encodes arithmetical properties of Hurwitz spaces.
