International student enrolments in United States institutions, 2010-11	
Australian universities are widely recognised as having the largest proportion of international students in tertiary enrolments. The OECD’s Education at a Glance 2011 includes a table showing that 21.4% of Australia’s tertiary enrolments are international, more than three times the OECD average of 6.4%, and six times the proportion of United States tertiary enrolments (3.5%). While the United States has the most international students of any country, these international students are distributed across a large number of institutions, and the total numbers of international students in individual institutions are relatively small – eight Australian universities have more international students than the leading United States host institution.  
Although the United States has a large number of institutions, international students tend to be concentrated in a small number of highly ranked institutions, as the table below shows. This table, compiled using data from the Institute of International Education and the National Centre for Education Statistics, shows the relative proportions of international students in the 25 institutions hosting the largest numbers of international students (these 25 institutions hosted 20% of all international enrolments in 2010-11).

Twenty four of the universities in this list were among the 25 largest hosts of international students in 2009-10. These 24 universities increased their international student enrolments by an average 9% in 2010-11, although the whole US sector grew by 5% in 2010-11.
For comparative purposes, the table also includes the 2011 Academic Rankings of World Universities (ARWU) for each institution. As the table shows, several of the largest hosts of international students have proportions exceeding the average for Australian universities, and all are placed with the top 400 universities in the ARWU rankings with 21 ranked in the top 100).
