This paper is notable as one of the a few formal replication studies in the geographical sciences. The study examines a prior study (DiMaggio et al. 2020) using a Bayesian spatial analysis of COVID-19 in New York City by replicating the study in Phoenix, Arizona. Through the replication study, we discover that in Phoenix, ethnic marginalization of majority Hispanic neighborhoods is more strongly associated with COVID-19 incidence than the racial marginalization of majority Black/African neighborhoods described by DiMaggio and others.
