ABSTRACT

&NA; There is a growing interest in using OpenStreetMap [OSM] data in health research. We evaluate the usefulness of OSM data for researching the spatial availability of alcohol, a field which has been hampered by data access difficulties. We find OSM data is about 50% complete, which appears adequate for replicating findings from other studies using alcohol licensing data. Further, we show how OSM quality metrics can be used to select areas with more complete alcohol data. The ease of access and use may create opportunities for analysts and researchers seeking to understand broad patterns of alcohol availability. HighlightsWe assess the reliability of OpenStreetMap data for estimating spatial availability of alcohol.We show that OSM contains about 50% of actually existing alcohol points of sale.We duplicate a previous study of alcohol related harms using OSM data.We use OSM quality metrics to select areas of higher quality data.We conclude that OSM is a useful supplementary data source for researchers.
