In response to the dramatic increase in the prevalence of obesity and diabetes, numerous U.S. cities have recently enacted taxes on sugar-sweetened beverages (SSBs). This presentation provides an overview of a multi-year project to evaluate the effects of beverage taxes in numerous cities, including Berkeley and Oakland, CA; Philadelphia, PA; and Boulder, CO. We collected original data from stores and through street intercepts and phone surveys of consumers, in both the treated cities and nearby comparison areas. We examine numerous outcomes, including price (the pass-through of the tax), sales, cross-border shopping to evade the tax, and consumption. The results indicate that the effects of these taxes vary by city. We find the largest effects from the tax in Philadelphia; we estimate that the tax of 1.5 cents/ounce was fully passed through to consumers and reduced the frequency of adults’ soda consumption by 31%, but had no detectable effect on the beverage consumption of children.
