The LSAC reports that "As of 2/21/14, there are 253,293 fall 2014 applications submitted by 36,304 applicants. Applicants are down 11.7% and applications are down 12.3% from 2013. Last year at this time, we had 69% of the preliminary final applicant count." If this year's applicants follow last year's pattern, we'll have approximately 52,614 total applicants for the class entering in fall 2014. Dan Filler has some historical data on the first year enrollment from 1964 to 2012 here. I link to some more comprehensive data (going back to the 1940s) here.
