The provided line graph displays the changes in the presence of young people aged 18-25 years old in universities in four Asian countries.
Overall, the trends in the percentage of the young students reveal both increases and declines, with Singapore and Thailand exhibiting the most pronounced growth, while the Philippines and Malaysia demonstrate lower numbers.
Singapore presents a contrasting trend, characterized by a robust rise from 15% in 1961 to 30% in 1971 and more gradual growth from 25% in 1981 to 36% in 1991. Beyond these timeframes, the graph drops between 1971 and 1981 to 25% and between 1991 and 2001 to 34%. Eventually, in 2011, it reaches the level of 40%. The data for Thailand illustrates the gradual decline of young students from 24% to 20% during 30 years until 1991, then it exhibits a sudden and significant upward trend, reaching the top level at 42%.
In both the Philippines and Malaysia, the percentage of students aged 18-25 years old demonstrates a slight but stable increase from 3% in 1961 to 15% in 2011 in Malaysia and from 7% to 19% during the same period in the Philippines. Furthermore, in Malaysia, following a brief ascent from 1961 to 1971 by 10%, the graph slows down and then stabilizes at the level of 15% from 1991 until 2011.
