Why do college offer need-based aid to Internationals?

<p>International Students as a Percentage
Applicants and Admits</p>

<p>1988-89 6% 3%
1991-92 8% 4%
1996-97 9% 5%
1999-00 10% 5%</p>

<p>A rough translation should show:
1999-00 1262 Applicants 125 Admits or about 10% acceptance rate."</p>

<p>Didn't quite get it. If they make up 10% of applicants, and only 5% of admits, then the odds of an international being admitted are only half what they would be for a domestic applicant. With a total admit rate currently of 10%, that would mean that only 5% of internationals are admitted (and most, I would expect, receiving no financial aid.) Did I miss something?</p>
