Sweden is a unitary state divided into 21 regions (''regioner'') and 290 municipalities (''kommuner''). Every region corresponds to a county (''län'') with a number of municipalities per county. Regions and municipalities are both local government bur have different roles and separate responsibilities. Health care, public transport and certain cultural institutions are administered by county councils. Preschools, primary and secondary schooling, public water utilities, garbage disposal, elderly care and rescue services are administered by the municipalities. Gotland is a special case of being a region with only one municipality and the functions of region and municipality are performed by the same organisation.
