In this note we consider the complex representation theory of $\mathrm {FI}_d$, a natural generalization of the category $\mathrm {FI}$ of finite sets and injections. We prove that finitely generated $\mathrm {FI}_d$-modules exhibit behaviors in the spirit of Church-Farb representation stability theory, generalizing a theorem of Church, Ellenberg, and Farb which connects finite generation of $\mathrm {FI}$-modules to representation stability.
