The given line graph presents the quantity of undergraduate students in certain four countries during the period from 1995 to 2015.
Overall, from the beginning of the period it is observed that the most significant number of undergraduates was in Sweden, whereas the lowest number of students studied at universities in Greece. But by the end of the period these two countries had changed completely in an opposite way. As for Spain and Austria, the number of students in 1995 was almost the same, and during the whole time it had been fluctuating and approximately equaled in 2015.
Starting with clearly opposite trends, it should be noted Sweden was initially leading in the number of graduates with 350 thousand students but in the end the statistics reached almost 200 thousand, which was the same quantity of the Greek students in 2015. However, Greece was considered to have the lowest number of undergraduates at the start, below 100 thousand people.
Concerning Spain and Austria, both started with almost equal numbers of students until 2010 around 240 and 260 thousand respectively, when the countries had a significant increase. But then, the quantity of the Spanish undergraduates reduced to almost 300 thousand, while Austria had fluctuated in growth by 2015 and the graduates had been counted at about 250 thousand.
