In Germany, the unemployment rate measures the registered unemployed as a percentage of the civilian labor force. The registered Unemployed as defined in the statistics collected by the Federal Employment Office and based on the register of persons out of work are all those persons who have reached the age of 15 but not yet the age of 65 who have no job or only a part-time job (at present less than 15 hours a week) and are looking for a job subject to compulsory insurance with a working time of no less than 15 hours a week. They must have registered at the appropriate job center and must not be certified as unfit for work.
