Wage Disparities in the Professorial Ranks

In a previous post, I presented data on wage inequality in the UC system amongst different types of high-earning employees; what I would like to do now is to discuss inequities in the professorial ranks (these statistics do not include medical, law, or business professors).

One way of approaching this data is to first look at the average salaries for assistant, associate, and full professors. For instance, in 2010, there were 3,246 full professors, and their average total compensation was $139,633. Meanwhile, during the same time period, we find 1,322 associate professors with an average gross pay of $117,527, and 984 assistant professors with an average total pay of $76,949.

While the system-wide average gross pay for all academic professors was $116,665 in 2010, if we look at this average on the different campuses, we find the following: UCLA - $137,683; Berkeley - $127,607; San Diego - $118,480; Santa Barbara - $115,349; Davis - $101,903; Riverside - $98,107; Irvine - $107,462; Merced - $88,229; and Santa Cruz - $99,797. Excluding Merced, we see that the difference between the average academic professor salaries at UCLA and Riverside is $39,576 or 34%.

Also, looking historically, we know that in 2004, there were 216 full professors making more than $200,000, and in 2006, the number of high earners dropped to 194, but in 2008, this same category jumped to 380, and in 2010, it went down slightly to 372. Therefore, the number of full professors making over $200,000 nearly doubled between 2006 and 2008 and has since stabilized. Meanwhile, if we look at the salaries of assistant professors during this same period, we find that the number of assistants making less than $70,00 stayed almost the same between 2004 and 2008: there were 577 assistant professors making less than $70,000 in 2004; 553 in 2006; 558 in 2008; and 401 in 2010. These statistics tells us that the salary growth for academic professors was concentrated at the top during the period of 2006 and 2008.

It would be interesting to look at the salary disparities in the different disciplines, but this information is not available. Over all, it appears that the biggest wage disparities occur between the campuses with the highest number of graduate students (UCLA, UCB, UCSD), and the ones with the highest percentage of undergraduates (UCR, UCM, UCSC).
