The bar chart shows information about the proportion of adults with high school education in two age cohorts in six distinct nations in 2010.
Overall, most American citizens in both age groups achieved high-school level, whereas China exhibited a sharp contrast, with both population groups showing the lowest figures. More importantly, the percentage of younger age brackets increased in most nations, but the scale of improvement varied substantially, from marginal in Germany to dramatic in South Korea and Brazil.
Looking first at the 55-64 population, about 90% of American residents in this age group finished their high school studies, followed closely by their German counterparts, reaching approximately 85%. Meanwhile, the proportion in Russia accounted for around 70% of the total, surpassing that in South Korea by a quarter. Finally, the figure in Brazil was recorded at about 25%, which was 10% higher than that in China, where only 15% of individuals belonging to this age group completed high school years.
Regarding the remaining age sector, Germany and the USA demonstrated a consistent level, with both registering roughly 88%. In stark contrast, Russia and Brazil recorded more substantial improvements, with increases of around 20% to 25%. Notably, South Korea displayed the most dramatic disparity, as nearly all young adults graduated. Finally, adults aged 25 to 34 in China made up one-fifth of the total, remaining the lowest figure among the others.
