Via the Cardinal Newman Society:
A new study from the American Academy of Religion and the Society of Biblical Literature found that there are fewer jobs being posted for college professors in theology and religious studies than there were prior to the economy tanking in 2008. The number of postings in 2009 was down 46 percent from the previous year across American higher education. In addition, the data show that fewer of the positions that are being offered are tenure track. In 2008, 82 percent of the positions offered were tenure track, but that number dropped to 51 percent in 2009 and 61 percent in 2010.
The study does not speculate on the reasons for the declines, but they most likely have to do with the recession that began in 2008. Other reasons could include less emphasis on religion relative to other subject areas, or lower student enrollment in religion courses.
