Nordic and Scandinavian Americans are Americans of Scandinavian and/or Nordic ancestry, including Danish Americans (estimate: 1,453,897), Faroese Americans, Finnish Americans (estimate: 653,222), Greenlandic Americans, Icelandic Americans (estimate: 49,442), Norwegian Americans (estimate: 4,602,337), and Swedish Americans (estimate: 4,293,208). Also included are persons who reported 'Scandinavian' ancestry (estimate: 582,549) on their census. According to 2021 census estimates, there are approximately 9,365,489 people of Scandinavian ancestry in the United States. Norsemen had explored the eastern coast of North America as early as the 11th century, though they created no lasting settlements. Later, a Swedish colony briefly existed on the Delaware River during the 17th century. The vast majority of Americans of Nordic or Scandinavian ancestry, however, are descendent of immigrants of the 19th century. This era saw mass emigration from Scandinavia following a population increase that the region's existing infrastructure could not support. Many prevailing traditions observed by Nordic and Scandinavian Americans are from this era, and are reflective of the lifestyle of rural immigrant communities during the late 19th century. Terminology The terms Scandinavian and Nordic are closely related and often erroneously used interchangeably. The Nordic countries are a geographic region which consists of Sweden, Norway, Denmark, Greenland, the Faroe Islands, Iceland, Finland, and Åland. Though these regions have a shared cultural history, they contain culturally distinct historical populations, including the Sámi people and the Norse people. By contrast, the term Scandinavia more selectively refers to just Denmark, Norway and Sweden, although other Nordic countries are sometimes included within this definition. The joint ruling of Denmark and Norway from the mid-14th century until 1814, and then the joint rule of Sweden and Norway until 1905, have contributed towards a closely allied culture. These three countries also share mutually intelligible languages, as they are all descended from Old Norse. Faroese and Icelandic are also descendent of Old Norse, though they have kept more of the old Norse grammar and spelling, while the Scandinavian languages have undergone more or less the same simplifications and are mutually intelligible and readable. The degree of ease with which people understand each other, however, varies depending on country and region of origin. History Early settlements By the 11th century, Norsemen had established a presence in Iceland and Greenland, in close proximity to continental North America. Several expeditions were made to what they called Vinland, near Newfoundland and Labrador. Although this was the most significant pre-Columbian contact with North
