On May 14th we added new salary data to the Cook County Open Data Portal containing annual salary information as of May 12, 2014. There are three previous salary data releases on the portal: September 16, 2011, September 22, 2011, and March 5, 2013. Moving forward we hope to release salary data on a quarterly basis. This release contains department names, job titles, salaries, employment start dates, and additional information.
We have provided column descriptions on the dataset page and as an attached file (under About >> Attachments).
