Administrative records are records created for administrative purposes, such as keeping a record of the members, activities, staff, etc. of the corresponding agency or institution. They were not designed for statistical purposes, but they do have a significant underlying statistical potential, and can be used to produce statistics as a by-product. Administrative records are varied and cover a wide range of topics. Some examples are population registers (population data), records of tax authorities (income data), registration of students in the educational system (education data) and medical registration (health statistics). When it comes to labour statistics, the main administrative records used are records of employment offices or unemployment benefits (data on registered unemployment), records of workers’ organizations (data on unionization, strikes, etc.), collective agreements (data on collective bargaining, wages, etc.) and labour inspection records (data on occupational accidents).
