question: In what region of the United States is the expression Uff da popular among Scandinavian Americans?
answer: Upper Midwest and Pacific Northwest
context: Title: Helen Hunt Falls
  Passage: Helen Hunt Falls is a waterfall located on Cheyenne Creek in the North Cheyenne Cañon Park of Colorado Springs, Colorado.  The falls are named in honor of Helen Maria Hunt Jackson (October 15, 1830 – August 12, 1885), a United States poet and writer who became an activist on behalf of improved treatment of Native Americans by the U.S. government.  She died in San Francisco, California in 1885 and was later buried in Colorado Springs.  The falls are located on North Cheyenne Creek immediately off of North Cheyenne Canyon Road in the North Cheyenne Canyon Park.  There is parking for about 30 vehicles at the falls and it becomes crowded early during summer months when visits to the canyon are popular among locals and tourists.  The Columbine Trail, which starts at the entrance of the Park by the Starsmore Visitor and Nature Center, terminates at Helen Hunt Falls.  Visitors can hike a short distance of about 2/3 of a mile up a moderately steep trail above Helen Hunt Falls to reach Silver Cascade Falls.
  Title: Public image of Sarah Palin
  Passage: Sarah Palin, while serving as Governor of Alaska, was nominated as the first female candidate of the Republican Party for Vice President of the United States.  Following the nomination, her public image came under close media scrutiny, particularly regarding her religious perspective on public life, her socially conservative views, and a perceived lack of experience.  Palin's experience in foreign and domestic politics came under criticism among conservatives as well as liberals following her nomination.  A poll taken by Rasmussen Reports just after the Republican National Convention in the first week of September 2008 found that Palin was more popular than either Barack Obama or John McCain; however, this perception later reversed.  At the same time, Palin became more popular among Republicans than McCain.  A February 2010 "ABC News/Washington Post" poll showed 71% of Americans felt Palin lacked the qualifications necessary to be President of the United States.
  Title: Jim Crow laws
  Passage: Jim Crow laws were state and local laws that enforced racial segregation in the Southern United States.  Enacted by white Democratic-dominated state legislatures in the late 19th century after the Reconstruction period, these laws continued to be enforced until 1965.  They mandated "de jure" racial segregation in all public facilities in the states of the former Confederate States of America, starting in 1896 with a "separate but equal" status for African Americans in railroad cars.  Public education had essentially been segregated since its establishment in most of the South after the Civil War.  This principle was extended to public facilities and transportation, including segregated cars on interstate trains and, later, buses.  Facilities for African Americans were consistently inferior and underfunded compared to those which were then available to European Americans; sometimes they did not exist at all.  This body of law institutionalized a number of economic, educational, and social disadvantages.  "De jure" segregation existed mainly in the Southern states, while Northern segregation was generally "de facto"—patterns of housing segregation enforced by private covenants, bank lending practices, and job discrimination, including discriminatory labor union practices.  "Jim Crow" was a pejorative expression meaning "Negro".
  Title: American entry into World War I
  Passage: The American entry into World War I came in April 1917, after more than two and a half years of efforts by President Woodrow Wilson to keep the United States out of the war.  Apart from an Anglophile element urging early support for the British, American public opinion reflected that of the president: the sentiment for neutrality was particularly strong among Irish Americans, German Americans and Scandinavian Americans, as well as among church leaders and among women in general.  On the other hand, even before World War I had broken out, American opinion had been more negative toward Germany than towards any other country in Europe.  Over time, especially after reports of atrocities in Belgium in 1914 and following the sinking of the passenger liner "RMS Lusitania" in 1915, the American people increasingly came to see Germany as the aggressor in Europe.
  Title: Uff da
  Passage: Uff da (sometimes also spelled huffda, uff-da, uffda, uff-dah, oofda, ufda, ufdah, oofta, or uf daa) is an exclamation or interjection expressing bafflement, surprise, or dismay.  Of Norwegian origin, the phrase was adopted by Scandinavian Americans in the Upper Midwest and Pacific Northwest region of the United States during the 19th century.  The Swedish exclamation "usch då" is similar in meaning and usage.
  Title: Swedish carpets and rugs
  Passage: The history of Swedish rugs reads similarly to the broader history of Scandinavian rugs, though with several distinctive, important developments.  First, it is important to note that Swedish people were creating weaves for a very long time before the craft began to be taken seriously as a valid avenue of Swedish artistic expression.  One of the most important Swedish rug-making techniques to have widespread practice and implementation was that which resulted in Rollakans, which are traditional flat weaves.  Very popular among Swedish folk-artists, Rollakans were often used as bed coverings and for general display purposes, and, as such, often featured appealing all-over patterns.  Such rugs are very highly sought after in today’s rug market due to their perception as quintessentially Swedish compositions.
  Title: Culture of Minnesota
  Passage: The culture of Minnesota is a subculture of the United States with influences from Scandinavian Americans, Irish Americans, German Americans, Native Americans, Polish Americans and numerous other immigrant groups.  They work in the context of the cold agricultural and mining state that has developed new high-tech industries (such as computers and medicine) that have brought affluence and a sense of distinctiveness.
  Title: Scandinavian Americans
  Passage: Scandinavian Americans or Nordic Americans are Americans of Scandinavian (in the broad sense), or part-Scandinavian ancestry, defined in this article to include Danish Americans (estimate: 1,453,897), Faroese Americans (no estimates), Finnish Americans (estimate: 677,272), Greenlandic Americans (estimate: 352), Icelandic Americans (estimate: 51,234), Norwegian Americans (estimate: 4,602,337), Sami Americans (estimate: 30,000), Swedish Americans (estimate: 4,293,208).  Also included are persons who reported 'Northern European' ancestry (estimate: 230,027) or 'Scandinavian' ancestry (estimate: 582,549).  According to 2010 census data, there are approximately 11,890,524 people of Scandinavian ancestry in the United States.
  Title: Hawaiiana
  Passage: Hawaiiana is a popular term of academia used in reference to history and various aspects of the culture of Hawai'i, currently a region and state of the United States.  The term is used especially in reflection of the periods of antiquity and the Kingdom of Hawai'i era.  Hawaiiana has become increasingly popular among students of history and sociology throughout the world.  The principal repository of Hawaiiana is the Princess Bernice Pauahi Bishop Museum in Honolulu on the island of O'ahu.  The institution is also called the Hawai'i State Museum of Natural and Cultural History and often shares artifacts and information with other institutions globally for the sake of research and study.
  Title: Simon Abraham Duplex
  Passage: The Simon Abraham Duplex is a historic house located in Portland, Oregon, United States.  Built in 1890 in the Queen Anne style, it is one of extremely few duplexes in the Eliot neighborhood remaining from the late 19th/early 20th centuries.  Its early ownership by German Americans and Scandinavian Americans testifies to the settlement by ethnic immigrants in this part of the former city of Albina.
