Here is a table with average retirement ages for different positions (including those with the x% @50 plans). CHP has the lowest average retirement age, and theirs is 53 years. State correctional officers and firefighters have an average retirement age of 60, local public safety employees have an average retirement age of 55, and these are some of the most widely touted “young” retirees.
None of these classifications have an average retirement age of 50.
