 By means of the State of Autonomies implemented after the Spanish Constitution of 1978, Spain has been quoted to be "remarkable for the extent of the powers peacefully devolved over the past 30 years" and "an extraordinarily decentralized country", with the central government accounting for just 18% of public spending, 38% by the regional governments, 13% by the local councils, and the remaining 31% by the social security system.In terms of personnel, by 2010 almost 1,350,000 people or 50.3% of the total civil servants in Spain were employed by the autonomous communities; city and provincial councils accounted for 23.6% and those employees working for the central administration (police and military included) represented 22.2% of the total.Peripheral nationalism continues to play a key role in Spanish politics.
