Germany’s northernmost state, bordering Denmark, owes much of its character to its position between the Baltic and North Seas, as well as to its islands and halligen. Home to approximately 3 million people, it is relatively sparsely populated and has Kiel as its capital. The Schleswig-Holstein Wadden Sea tidal flats and wetlands form a national park with world natural heritage status. Tourism is a mainstay of the state’s economy, as are maritime sectors such as shipbuilding, port logistics, fisheries, and marine research and technology. There are three national or ethnic minorities in Schleswig-Holstein: the Danish minority, the Frisian ethnic minority, and the German Sinti and Roma.
