About the data

Salary scales

The university publishes salary scales for its faculty members that incorporate their "rank" — from lowest to highest: assistant professor, associate professor or professor — and provide additional guidance based on the time a person has spent at that rank.

But compensation decisions are largely discretionary, and in many cases an individual's year-to-year pay doesn't follow the progression laid out in the salary scales.

"Generally, a number of factors influence the individual salary data in UC’s database, including the employee’s position, performance, scope of responsibilities, knowledge, experience, duration of employment at UC, and whether it is a full-time or part-time appointment, summer salary, or approved additional compensation, among other considerations," said UC spokesperson Claire Doan in an email.

This means a professor or lecturer’s salary might decrease from year to year or increase dramatically, even if they maintain the same rank.

In particular, salaries for part-time lecturers can be pro-rated based on the amount of time they spend teaching, Doan said. This is one reason why salaries for part-time lecturers can be a few thousand dollars while those for full-time, senior lecturers can be more than $250,000.


We're only analyzing full professors, assistant professors, associate professors and lecturers. We've dropped information about administrators, deans, adjunct professors, lecturers for the summer session and others. We couldn't associate all faculty members with a department, and we've chosen to exclude those people from this website (they're still available in our processed data).

Also, an individual’s salary can vary year-to-year based on the portion of time they spend on campus. Some salaries are based on the academic year and some on the fiscal year. Making departmental comparisons is especially difficult because some departments may have more experienced faculty who would consequently be paid more.

Another technical note: In all cases, we're examining the faculty member's gross salary, which is the total amount they were paid by the university. Their base salary might be different.

Finally, we've merged salary and departmental information by matching the first and last names of individuals. That automatic process might fail for people with similar names. If you spot an error, let us know.

About this project

Why another salary database?

The university publishes employee pay data on its website annually. But it doesn't have information on faculty departmental affiliations, and it's not easy to trace a person's salary over multiple years.

We merged data from 2010 to 2015 from the university with 2006 to 2009 pay data from the UC Berkeley Library. Then we added information about departmental affiliations from the UC Berkeley directory, where available. The result is the most complete public, downloadable database of pay information for the UC Berkeley faculty.

We're publishing the raw data and code used to create this database for journalists and researchers. Our pipeline can be used to analyze data from other campuses or even for other positions within the university — for example, administrators or athletic personnel.
