Abstract: For any class $ \mathcal{M}$ of 4-manifolds, for instance the class $ \mathcal{M}(G)$ of closed oriented manifolds with $ \pi_1(M) \cong G$ for a fixed group $ G$, the geography of $ \mathcal{M}$ is the set of integer pairs $ \{(\sigma(M), \chi(M)) \vert M \in \mathcal{M}\}$, where $ \sigma$ and $ \chi$ denote the signature and Euler characteristic. This paper explores general properties of the geography of $ \mathcal{M}(G)$ and undertakes an extended study of $ \mathcal{M}(\mathbf{Z}^n)$.
