There are also differences in the level of self-governance for the sub-regions of a member state. Most states, especially the smaller ones, are unitary states; meaning all major political power is concentrated at the national level. 9 states allocate power to more local levels of government. Austria, Belgium and Germany are full federations, meaning their regions have constitutional autonomies. Denmark, Finland, France and the Netherlands are federacies, meaning some regions have autonomy but most do not. Spain and Italy have system of devolution where regions have autonomy, but the national government retains the right to revoke it. \
