While local government is found in all federal countries, its place and role in the governance of these countries varies considerably. In some countries, local government is considered an essential part of the federal nature of the state and recognized in the constitution as such, whereas in others it is simply a creature of the subnational states/provinces. When referring to local government it is more correct to refer to local governments (plural), as these institutions come in all shapes and sizes, performing widely divergent functions. They range from metropolitan municipalities of mega-cities to counties, small town councils, and villages. Their focus is either multi-purpose in the case of municipalities or single purpose in the case of special districts and school districts. What unites these institutions of state is that there is no level of government below them. That is also their strength and the source of their democratic claim - they are the government closest to the people.
