Estimated reduction in energy intake from a 10% SSB tax by age
Age Mean reduction in daily energy intake (kcal/person/day)
Female Male Overall
18-24 3.7 (2.9 to 4.5) 4.7 (3.7 to 5.8) 4.2 (3.3 to 5.2)
25-34 2.7 (2.1 to 3.3) 3.1 (2.4 to 3.8) 2.9 (2.3 to 3.5)
35-44 2.2 (1.7 to 2.7) 2.2 (1.7 to 2.7) 2.2 (1.7 to 2.7)
45-54 1.3 (1.0 to 1.6) 1.6 (1.3 to 2.0) 1.5 (1.1 to 1.8)
55-64 1.0 (0.8 to 1.2) 1.3 (1.0 to 1.6) 1.2 (0.9 to 1.4)
65-74 0.5 (0.4 to 0.7) 1.3 (1.0 to 1.6) 0.9 (0.7 to 1.1)
75+ 0.7 (0.6 to 0.9) 0.9 (0.7 to 1.1) 0.8 (0.6 to 1.0)
Overall 1.9 (1.5 to 2.3) 2.3 (1.8 to 2.9) 2.1 (1.7 to 2.6)

Estimates are based on a tax pass on rate of 90%, price elasticity of −0.9 (range is for 80% and −0.8 respectively, and 100% and −1.0). Estimates for each age group are weighted for sex; and the overall estimate is weighted for age and sex of the Irish population.
