Understanding the radiogenic neutron production rate through the (${\alpha}$, n) reaction is essential in many fields of physics like dark matter searches, neutrino studies, nuclear astrophysics and medical physics. This white paper provides a review of the current landscape of (${\alpha}$, n) yields, neutron spectra and correlated ${\gamma}$-rays calculations, and describes the existing tools and the available cross-sections. The uncertainties that contribute to (${\alpha}$, n) yield calculations are also discussed with plans for a program to improve the accuracy of these estimates. Novel ideas to measure (${\alpha}$, n) cross-sections for a variety of materials of interest are presented. The goal of this study is to reduce the uncertainty in the expected sensitivity of next-generation physics experiments in the keV--MeV regime.
