Most engineering schools are reporting declines in enrollment. This is hardly surprising since most engineering curriculums, including CS, are difficult compared to other fields of study. Without the prospect of a good job waiting for them, many college students are veering away from these majors.
Update: Yuhong correctly points out that this is mostly at the undegraduate level. Graduate schools are finding enough students, at least according to Yuhong. I think this is expected: if job prospects are bad, people won’t enter the system but once they’ve entered it, they will stay in it longer if jobs are scarse.
