This database is a living document. We update it regularly and are always on the lookout to make it more robust and precise. If you think we are missing a government unit we should include, please let us know.

While we make every reasonable effort to vet the accuracy of compensation included in the database, it is impossible to double-check all numbers in an undertaking of this magnitude. The basic building blocks of this database are reports provided by public agencies and it is possible errors in those initial reports or others made along the way will be reflected in the numbers we publish. That is why we need help from the public to point out problems.

If you spot something that isn’t right, or if information is missing for a government unit you care about, please contact our data coordinator.
