The major reason for Danish emigration was the search for a better standard of living. The promise of free or inexpensive land, better wages, and the possibility to create a better life for themselves and their children made Danes leave Denmark to move to the US.
In the early 1880’s, the Danish population increased rapidly, unemployment grew and wages were low. The eldest son inherited the land, and younger children had little hope of owning a farm. Industrialization also made many traditional jobs obsolete. Overall, it was very difficult to earn a living and for young people to earn enough money to start a family.
In the United States, on the other hand, any immigrant could claim 160 acres of unoccupied government land, homestead it, and earn title in five years in accordance with the Homestead Act of 1862. Wages were also higher, making it possible to save up and buy a farm or piece of property or create a business within a foreseeable number of years.

A high rate of immigration is found in the parts of Denmark where the price for land was high and which were dominated by large estate owners. This includes the areas of
Lolland-Falster,
Langeland and southern Funen. A somewhat high percentage left from the island of
Bornholm and
North Jutland as well.
Central Jutland and
North Zealand contributed less to the emigration. In central Jutland, there were opportunities for land as the cultivation of the heath was taking place. In North Zealand,
Copenhagen was the attracting magnet. The majority of Danish emigrants came from the capital city of Copenhagen and from the towns, which was not the case in Norway and Sweden.
A small proportion of emigrants left for religious reasons – in particular Mormons and Baptists. The Mormons carried out missionary work in Denmark. They also organized group emigration travel, without any up-front out-of-pocket cost to the individual. Many single women joined the Mormons, and Salt Lake City and Utah is home to many Americans with Danish heritage.

In 1864 almost a fourth of Denmark was lost when Slesvig and Holsten fell to Germany. Afterwards, mandatory German military service and repression of Danish culture caused many Danes to leave the area to create a new life for themselves elsewhere.
Finally, some people had personal, non-financial reasons to emigrate. They left to join a loved one in the new country, due to an unhappy love affair or a family feud, or simply to pursue adventure in the new world.
