  • Values are reductions from median intake levels for each demographic subgroup.

  • *Income deciles are based on the national income of the 164 countries included in the study. Each decile is comprised of 16 countries except the four lowest deciles, which are each comprised of 17 countries. The per capita income range (PPP-adjusted in thousand US$) for each decile: (1st) $0.6-$1.5, (2nd) $1.5-$2.7, (3rd) $2.7-$5.3, (4th) $5.5-$8.0, (5th) $8.3-$10.8, (6th) $11.1-$15.2, (7th) $15.3-$20.3, (8th) $20.6-$29.4, (9th) $30.4-$40.9 and (10th) $41.3-$127.2.

  • PPP, purchasing power parity; SSB, sugar-sweetened beverage.
