Did I Get This – Proportions (Overview)
Using data from 2008, the American Association of Community Colleges (AACC) reports that community college students constitute 46% of all U.S. undergraduates. Given the downturn in the U.S. economy, the AACC anticipates an increase in this percentage for 2010. A poll of 500 randomly chosen undergraduates taken in 2010 indicates that 52% are attending a community college.
