The neurosurgical population consists of professors, consultants, specialised senior registrars, and doctors in training (senior registrars, trainees and young doctors to be educated as neurosurgeons). Knowing number and size of the neurosurgical departments in each European country, the number of staff members, the politics of retirement (age, educational level) and the age of every neurosurgeon it is possible to calculate the exact number of trainees needed per year to maintain a state of balance in every single European country. With Denmark as a model we based our assessments partly on a simple calculation model of the exact annual number of neurosurgical trainees or senior registrars and partly used an actuary flow model for calculation. In Denmark with 5 neurosurgical departments, 5.2 mill. population and a retirement age of 70, we have an average of 1-2 newcomers per year and maintain a bulk of 10 senior registrars in education. Thus there will be a balance between intake of newcomers and retirement, of course with some unknown factors as unforeseen dismissal or resignation, death rate among neurosurgeons and transfer to private practice.
神经外科领域的人员包括教授、顾问、专业高级住院医师以及正在接受培训的医生（高级住院医师、实习生和即将接受神经外科医生培训的年轻医生）。了解欧洲每个国家神经外科科室的数量和规模、工作人员数量、退休政策（年龄、教育水平）以及每位神经外科医生的年龄后，就有可能计算出每个欧洲国家每年为保持平衡所需的实习生的确切数量。我们以丹麦为范例，部分评估基于神经外科实习生或高级住院医师确切年度数量的简单计算模型，部分则使用精算流量模型进行计算。在丹麦，有5个神经外科科室，人口520万，退休年龄为70岁，我们平均每年有1 - 2名新人加入，同时保持10名高级住院医师在培训。因此，新人入职与退休之间将达到平衡，当然还存在一些未知因素，如意外解雇或辞职、神经外科医生的死亡率以及转入私人执业等情况。
