Answer
Brief Explanations:
Examine the bar - heights for the 20 - 21 age group across years 2001, 2006, 2011, and 2016. In 2001, the enrollment (blue bar) is around 6 thousand. In 2006 (yellow bar), it is higher, around 7 thousand. In 2011 (striped blue bar), it is lower than 2006 but higher than 2001, and in 2016 (yellow - dotted bar), it is lower than 2011. So, it increased from 2001 to 2006 and then decreased.
Answer:
Increased and then decreased
