Despite the central role of species distributions in ecology and conservation, occurrence information remains geographically and taxonomically incomplete and biased. Efforts to address this problem, such as targeted data mobilization and advanced distribution modelling, all crucially rely on a solid understanding of the patterns and determinants of occurrence information. Numerous socio-economic and ecological drivers of uneven record collection and mobilization among species have been suggested, but the generality of their effects remains untested. Here, we provide the first global analysis of patterns and drivers of species-level variation in different metrics of occurrence information.
