The Swedish Police Authority is the national police force (Polisen) of the Kingdom of Sweden. The first modern police force in Sweden was established in the mid-19th century, and the police remained in effect under local government control up until 1965, when it was nationalized and became increasingly centralized, to finally organize under one authority January 1, 2015. Concurrent with this change, the Swedish Security Service formed its own agency. The new authority was created to address shortcomings in the division of duties and responsibilities, and to make it easier for the Government to demand greater accountability. The agency is organized into seven police regions and eight national departments. It is one of the largest government agencies in Sweden, with more than 28,500 employees, of which police officers accounted for approximately 75 percent of the personnel in 2014. It takes two and a half years to become a police officer in Sweden, including six months of paid workplace practice. Approximately a third of all police students are women, and in 2011 women accounted for 40 percent of all employees.
