Another consequence of increased enrollment has been a more unbalanced composition of the residences. Traditionally, students from all years of study have lived in residence, but increasingly, very few upper year students continue to live on campus, thus making way for more first years. In 2006, Alexandra Hall, traditionally the all-women's residence, was made co-ed for the first time with rooms in the basement alternating between male and female occupants as well as one wing of the first floor becoming all-male. In addition, two of the five bays were re-converted to co-ed living spaces in 2006.
