The line chart above illustrates the proportion of people who smoke and consume alcohol in the USA, Japan, Holland, and Turkey over a period of four decades. Overall, it is observed that citizens of these territories are making efforts to reduce smoking over time, while alcohol consumption remains prevalent in every nation.
In the USA, the percentage of heavy smokers peaked in the 1960s, reaching nearly 60% before gradually declining to below 50% by 1980. This trend then correlates with Japan, which started with 50% of smokers and experienced a slight decrease over the next two decades. By 2000, the percentage of smokers in both the USA and Japan stabilized around 35%. Conversely, Holland began with 40% of smokers in 1960, slowly reducing to 20% by the end of the period.
In terms of alcohol consumption, the people of Holland consumed one gallon in 1960, which peaked at around three gallons by 1980 and remained steady for the following 20 years. Residents of the United States started with about two gallons of alcohol consumption, which increased by ten liters by 1980, but then consistently declined until the end of the period. Finally, the public in Turkey maintained a steady volume of alcohol consumption, which never exceeded half a gallon throughout the years.
