The bar chart illustrates the proportion of the teenage population in four different countries based on the percentage of overweight adults in 1980, 1990, and 2000.
Overall, the percentage of overweight adults in the teenage population significantly increased during each period. Notably, in 2000, the USA had the highest percentage compared to the other three countries.
In terms of the adult population, Japan had 2% in both 1980 and 1990, while the percentage saw a slight increase in the final period. Finland’s adult percentage rose from around 5% to 15% during these years. Conversely, Australia remained below 10% initially but nearly reached 20% by the end of the period. The USA’s teenage population was at 15% in 1980, approximately 23% in 1990, and reached about 30% in the following decade.
Furthermore, in 1980, Japan had the lowest percentage during this time, while Finland and Australia had the same percentage level, with the USA almost touching 15%. By 1990, Japan, Finland, and Australia saw a rapid increase in their percentages, with the USA’s adult population reaching 23%. In 2000, there was a significant climb in each country’s teenage population.
Consequently, the percentage of the adult population is expected to continue increasing in the upcoming trend across these four countries. Additionally, the USA’s percentage is projected to be higher in the future.
