Employee attrition rate


The annual City of Austin Attrition rate measures the turnover rate of employees by a given department and averaged across departments. This data comes from the cities Human Capital Information System called Banner. The city uses this information for performance measurement based on separations by department.


The data has remained constant as the city has not seen great increases or decreases in the attrition rate between FY 2018 and FY 2021. Due to Covid related circustances we are seeing an increased turnover rate from fy21-22.

Additional Measure Insights

This data is compiled by department from the Banner Reporting System. It is important to note segmentation in this data set as turnover varies across departments. Departments with higher rates of attrition may have a small amount of employees and thus one separation will appear more dramatic to their average. The Human Resources Department is researching options for further segmentation of this measure.  Currently, the measure is segmented by department, but the hope would be for future systems to allow for additional segmentation options.
