Evaluating the Berkeley Soda Tax
When Berkeley, CA became the first city in the U.S. to pass a significant excise tax on sugary drinks in 2014, PHI was hired to evaluate its impact. Lynn Silver, PHI’s senior advisor on chronic disease and former assistant health commissioner in New York City, worked with PHI’s Survey Research Group and the University of North Carolina to evaluate the tax’s impact on consumption patterns and prices. Their results showed that the $0.01 per ounce soda tax is working as intended: the fee was passed on to the retail price of sugar-sweetened beverages (SSBs) in large and small chain supermarkets and gas stations. View the preliminary findings.
In 2017, PHI and the University of North Carolina completed a second evaluation of the tax. Published in PLOS Medicine, the largest-to-date evaluation looked at the first 12 months of the tax's implementation, and showed a 9.6% drop in sugar-sweetened beverage purchases. Meanwhile, the sales of untaxed healthier beverages rose significantly, by 3.5%—and sales of water rose by 15.6%. The study found no negative impact on store revenue or consumer grocery bills, and the tax helped the city raise $1,416,973 for nutrition and obesity prevention activities in schools, childcare and other community settings.
