The CounterTobacco.org image gallery is now home to a series of chloropleth maps that have been developed and shared by site users. Chloropleth maps are an easy way to visualize how a measurement varies across a geographic area — for example, quantity of point of sale advertising or tobacco retailer density – and make a big impression on policy makers. Visit our image galleryfor access to new maps of tobacco retailer outlet density in the City of Buffalo, Erie County, New York and point of sale advertising quantity in Ramsey County, Minnesota. Thank you to Dr. Andrew Hyland and Andrea Licht of Roswell Park Cancer Institute, Betsy Brock of Association for Nonsmokers – MN and Ramsey Tobacco Coalition for sharing their work!
