The increasing number of PhD students within BIRA-IASB brings with it a rejuvenation of the population; however, this rejuvenation is limited to contractual staff. The lack of resources to recruit statutory staff causes a predominance in the statutory staff of people above the age of 45.
The bulk of staff (statutory and contractual together) are in the 35-44 age group, which includes mainly contractual personnel. Only the 55-64 age group is dominated by statutory staff.
