Why would you ever limit admission to 1,200 when you have freshman residence spaces of !,400 or more? I doubt Emory wants to limit the number of incoming freshmen.
They were 1,388 last year and should be within 50 of that amount this year if the math is similar.
Other than ED1, they yielded 19.5%. If they do the same this year, they should be a little over 1,400. They probably have an algorithm based on statistics of admitted students how many will accept. Maybe they are shooting among a stronger group and expect a lower yield. They will probably land close to where they want.
