Abstract: In this work, we analyze observational constraints on power-law cosmology, which is characterized by two key parameters: the Hubble constant (H0) and the deceleration parameter (q). Using the latest 31 data points of observational Hubble data, we obtain bounds on these parameters. Our results indicate that power-law cosmology provides a good fit to the Hubble data, with the estimates closely matching recent findings reported in the literature. Nevertheless, while this model captures several major aspects of cosmic evolution, it falls short in accounting for finer details, particularly the dynamical transition of cosmic acceleration.
