The total reaction cross section ${\sigma }_{\mathrm{reac}}$ is a valuable measure for the prediction of $\alpha$-induced reaction cross sections within the statistical model and for the comparison of scattering of tightly bound projectiles to weakly bound and exotic projectiles. Here we provide the total reaction cross sections ${\sigma }_{\mathrm{reac}}$ derived from our previously published angular distributions of elastic $\alpha$-nucleus scattering on ${}^{89}\mathrm{Y}$, ${}^{92}\mathrm{Mo}$, ${}^{112,124}\mathrm{Sn}$, and ${}^{144}\mathrm{Sm}$ at energies around the Coulomb barrier.
