Universities began operating in the present borders of Canada in 1802. As annual enrolments grew to 1,147,233 in 2012, so too did university expenditures. Government contributions to university revenues fluctuated from 62% in 1920 to 46% in 1935, reaching a high of 81% in the mid- to late 1970s, then falling to 48% in 2014. Annual university revenues increased about 275 times between 1920 and 2014 (in constant 2014 dollars), from $129.3 million to $35.5 billion. In the two centuries between 1813 and 2013, undergraduate fees (in constant 2013 dollars) increased by a factor of 24, from $236 to $5,720.
