Access to grocery stores

This study by Johan Stålnacke from Statistics Sweden examines the accessibility of grocery stores for populations between 2001 and 2006. Utilizing the national road network and various distance thresholds (300m, 600m, 1500m, 10000m), the analysis reveals a decrease in both the number of grocery stores (from 6,564 to 5,953) and access to these stores over the studied period. The methodology applied can be adapted for other statistical analyses, demonstrating the capability of handling large datasets effectively for national assessments.
