Abstract: Let $ C$ be a bounded closed convex subset of a Banach space $ X$. It is shown that, in the category sense, almost all $ 1$-set-contractions $ f:C \to C$ are condensing. To know how the condensing mappings are scattered in the set $ {\Sigma _1}(C)$ of $ 1$-set-contractions it is proved that the set of noncondensing mappings is dense in $ {\Sigma _1}(C)$.
