This figure illustrates the rate in which disability cases have been reviewed by the PEBs in each service (number of cases adjusted by the total population of each respective service for the particular year). For the Army, the rate of disability cases reviewed increases by 87% from 8.2 per 1000 personnel in 1983 to 15.3 in 1994. For the Navy, the rate of disability cases reviewed increased by 120% from 15 per 1000 personnel in 1985 to 33 in 1994. For the Air Force, the rate of disability cases reviewed increased by 49% from 6.9 per 1000 personnel in 1990 to 10.3 in 1995.

These data include reviews of both active duty personnel and temporary disability retired list (TDRL) personnel. TDRL personnel are those who have had a previous PEB review and were ruled to have a temporary disability. As such, the data may not reflect new cases of disability within each year, and could be influenced by changes in the definition of eligibility for PEB review over time.
