What does this mean about yield rate?

<p>Hi, I'm not sure if this is the right spot to ask and I'm sorry if I'm posting in the wrong area.</p>

<p>I noticed that some schools might have 100 applications, 60 are accepted but only 40 actually attends so that's a yield rate of 66%. So what happens to the extra 20 slots that wasn't taken by the accepted students? Does it go to left over applicants or the 20 slots stays empty?</p>

<p>Thanks, I've searched but can't find anything.</p>

<p>They remain empty. Colleges admit a certain amount of students with the presumption that only a certain percentage will matriculate.</p>

<p>Thanks ChicagoBears1!</p>

<p>No problem!</p>

<p>When a hotel or airline does it, it’s called overbooking. If everybody with a reservation actually showed up, flyers would be bumped and guests would be camped out in sleeping bags in the lobby (or sent down the street to a competitor).</p>

<p>Sometimes colleges do get more takers than expected. They may open more sections of introductory courses, turn dorm lounges into rooms/rent space in nearby hotels, invite students to defer admission for a year, and plan to admit fewer applicants next year.</p>
