Moreover, aged between 45 to 74 experience a steady fall and it ends with under half of the total. Meanwhile, ex-drinkers in the USA have the smallest percentage for people aged 16 to 54, at below tenth. In contrast, the individuals between 55 to 74 years old become the highest number of ex-drinkers, at under 40%.

Lastly, the percentage of light drinkers from 16 to 34 is marginally higher than people aged between 35 to 74, at over 30%. And the number of light drinkers becomes the lowest, at less than 10% in the 65 to 74 year olds.
