Quantitative controls on the number and/or location of alcohol retail outlets: an overview of approaches in the USA and Canada

Quantitative controls on the number and/or location of alcohol retail outlets are widely used across the USA and Canada but vary significantly in structure and stringency. While some jurisdictions impose multiple controls, others apply none. Understanding these policy approaches provides insight into regulatory frameworks but does not indicate enforcement levels or public health impact. Further research could examine how these measures are implemented and whether different models influence alcohol availability.
