The state of Minnesota is located in the United States' Upper Midwestern region. With over 5.75 million people living there, it ranks as the 22nd most populous and 12th largest state in the United States. The western prairies of Minnesota are home to intensively cultivated fields; a portion of the southeast's deciduous forests that have been cleared, farmed, and settled; and the North Woods, which are used for mining, forestry, and recreation but are less populated. The state is known as the "Land of 10,000 Lakes" because it has over 14,000 bodies of fresh water that are at least ten acres in size and covers roughly a third of the state. The Minneapolis–Saint Paul metropolitan area, also known as the "Twin Cities," is where more than 60% of Minnesotans live. It is the state's main political, economic, and cultural center. The Twin Cities are the 16th largest metropolitan area in the United States, with approximately 3.7 million people living there. Other minor metropolitan and micropolitan statistical areas in the state include Duluth, Mankato, Moorhead, Rochester, and St. Cloud. Since the Woodland period in the 11th century BCE, various indigenous peoples have lived in Minnesota, which gets its name from the Dakota language. There were two distinct branches of the indigenous Hopewell tradition that emerged between 200 and 500 CE: Trempealeau Hopewell in the Mississippi River Valley in the south, and the Laurel complex in the north. The Oneota people and other speakers of Siouan made up the Upper Mississippian culture, which flourished until the arrival of Europeans in the 17th century. The first Europeans to enter the area were missionaries and explorers from France, who met the Dakota, Ojibwe, and various Anishinaabe tribes. In 1803, the United States purchased the vast French holding in Louisiana, which included a significant portion of the area that is now Minnesota. In 1858, the Minnesota Territory was admitted to the Union as the 32nd state, following several territorial reorganizations. The only state motto in French is L'Étoile du Nord, which is the state's official motto; Minnesota's name, which translates to "The Star of the North," was given to the state shortly after it became a state. It is a reference to the state's early French explorers as well as its status as the northernmost state in the United States. As a part of the American frontier, Minnesota attracted settlers and homesteaders from all over the country, and its growth was initially centered on the construction of railroads, agriculture, and timber. Early in the 20th century, a large number of European immigrants arrived, particularly from Scandinavia, Germany, and Central Europe; Many were connected to the 1848 failed revolutions, which had an impact on the state's growth as a labor and social activism hub. In the late 19th and early 20th centuries, major social, economic, and political shifts were sparked by Minnesota's rapid urbanization and industrialization; In terms of labor rights, women's suffrage, and political reform, the state led the way. Because it has supported every Democratic presidential candidate since 1976—longer than any other state in the United States—Minnesota is considered to be Democratic-leaning. The core of Minnesota's economy has diversified since the late 20th century, moving away from traditional industries like agriculture and resource extraction and toward services, finance, and health care; As a result, in terms of GDP and per capita income, it ranks among the richest. The state still serves as a hub for Scandinavian, German, and Lutheran cultures, with seven Ojibwe and four Dakota reservations recognized by the federal government. Minnesota has become more multicultural over the past few decades as a result of increased domestic migration as well as immigration from Latin America, Asia, the Horn of Africa, and the Middle East; The state has the most Somali Americans and the second most Hmong people in the country. In terms of employment, median income, safety, and governance, Minnesota ranks among the best states. It also has one of the highest levels of education and standard of living in the United States.
