A philosopher on the earlier thread about admissions posted a comment raising issues that deserve separate attention. She writes:
I don't want to start a wave of paranoia, but I think it might be worth it for the profession to start some long term planning in grad admissions. It is my understanding that in about a decade (ie not long after the incoming grad class finishes their dissertations), the college age population is going to drop somewhat dramatically. The statistic I have heard floated is that this year's kindergarten class is the smallest since WWII. With about half as many students as are currently enrolled in college to teach, I suspect that universities will be cutting the number of faculty. What this likely means is no retirement replacements. Rather than create another situation like that of the late 80s and early 90s, the profession might well want to begin thinking now about how to handle these demographic changes. Grad admissions might be a clear area to strategize around. Another area might be the inclusion of philosophy into HS curricula (so there is a non-university arena for job-seekers). And while I never thought about these issues as a grad student (I didn't even know they existed), it might well be some handy information for grad students to have as they think about getting through their programs in a timely manner.
My impression of the demographics (at least for the US) is similar to this philosopher's. References to data or trends, analyses of the implications of demographic shifts, and what the profession should be doing about all this are welcome in the comments.
