<p>Interesteddad's comment in another thread about the long-range market response in the 70's by some colleges forseeing the post-baby-boom reduction in college-going HS graduates got me thinking. I found some data for Boston College which at least spans the post-baby-boom low points. Although I know very little about BC, the data were available via their fact books. Thought it would be interesting to see how their application, acceptance history, & SATs (as a surrogate for academic quality) looked over the years relative to the HS graduate bubble.</p>
<p>First, from the National Center of Educational Statistics (<a href="http://nces.ed.gov/programs/digest/d04/tables/dt04_102.asp%5B/url%5D">http://nces.ed.gov/programs/digest/d04/tables/dt04_102.asp</a> ), here is the history of HS graduate population (in thousands)...note that this is just graduates; college-bound HS graduates likely increased during the 80's & 90's.</p>

<p>So the bottom hit in 1991 (college class of '95) and the latest cycle of upturn started in earnest around 1997 (college class of 2001). (Of course this ignores the increasing prevalence of HS graduates to attempt to matriculate to college.)</p>
<p>Next, I pulled the # of applications, acceptance rate, SAT scores (average of the 25% and 75% #'s), and endowment data from BC's factbooks. I normalized all to 100% at the start date: class of 1989 (or fall 1985) for all data except endowment, which I could only guesstimate back to 1992, or class of '96. The purpose of the normalization was merely to observe trends. Also note I did my own crude recentering of 1995 & prior SAT scores by assuming that 1995 & 1996 (classes of '99 & '00, the 2 years that crossed the re-centering) were the same average once recentered.</p>

<p>You can see that BC's applications mirrored the downturn in HS graduates, and hit a low for the class of '95 (fall 1991), the beginning of the bottom-out period for the population in general. In response to the downturn, BC's acceptance rate had been climbing prior to the class of '95, & hit an all-time high for that class. (Looks like they over-admitted in that worst year because 1st-year enrollment spiked as well, ~ 10% above there fairly steady enrollment of 2200 to 2300 students for the freshman class.) Interestingly, the SAT average held fairly steady during that time period. BC must have responded somehow to increase enrollments after that bad year, because they pulled out of the low point faster than the HS population. Also, during that pull-out period, SAT scores started a slow climb. With the population of HS graduates 14% greater for the class of 2008 vs 1989, BC has seen a growth of 39% in applications and 7% in SAT scores, and their acceptance rate is back to its class of 1989 rate. Although the endowment history in incomplete, the other big change here is in BC's endowment, which rose most greatly (as a percent) during their bottom-of-the-cycle pull out period. I can only suppose, as interesteddad has previously mentioned, that BC has used their upturn in endowment to attract new talent, both in numbers and in academic quality, perhaps through creative scholarships. I find it most interesting that their SAT scores not only did not recede during the down-turn, but rose significantly post-down turn.</p>
