Adherence
Implementing a tax on sugar-sweetened beverages (SSBs) significantly reduces their consumption, with higher elasticity observed in lower-income households, leading to substitution toward water and milk.
If you are in a lower-income household, a tax on sugary drinks makes them less affordable, prompting you to switch to water or milk. This substitution is a key strategy for reducing obesity risk in this demographic.
GoodSupportsHIGH confidence
Results of a recent analysis indicate that the demand for soft drinks is elastic: a 10.0% increase in the price of soft drinks is associated with a decrease in consumption of 10.1%... Higher elasticities were found among households in more deprived areas and from the lowest income quintiles. Consumers substituted water and milk when the price of soft drinks rose.
Why this rating
Based on national survey data and elasticity calculations by INSP, though the tax itself was not yet enacted, the predictive modeling is robust.
