There are 29 counties in the U. S. state of Utah. There were seven counties established under the provisional State of Deseret in 1849: Davis, Sanpete, Salt Lake, Tooele and Weber; the Territory of Utah was created in 1851 with the first territorial legislature meeting from 1851–1852. The first legislature re-created the original counties from the State of Deseret under territorial law as well as establishing three additional counties: Juab and Washington. All other counties were established between 1854 and 1894 by the Utah Territorial Legislature under territorial law except for the last two counties formed and Duchesne, they were created by gubernatorial proclamation after Utah became a state. Present-day Duchesne County encompassed an Indian reservation, created in 1861; the reservation was opened to homesteaders in 1905 and the county was created in 1913. Due to dangerous roads, mountainous terrain, bad weather preventing travel via a direct route, 19th century residents in present-day Daggett County had to travel 400 to 800 miles on both stage and rail to conduct business in Vernal, the county seat for Uintah County a mere 50 miles away.

In 1917, all Uintah County residents voted to create Daggett County. Based on the 2010 United States Census data, the population of Utah was 2,763,885. Just over 75% of Utah's population is concentrated along four Wasatch Front counties of Salt Lake, Utah and Weber. Salt Lake County was the largest county in the state with a population of 1,029,655, followed by Utah County with 516,564, Davis County with 306,479 and Weber County with 231,236. Daggett County was the least populated with 1,059 people; the largest county in land area is San Juan County with 7,821 square miles and Davis County is the smallest with 304 square miles. The Federal Information Processing Standard code, used by the United States government to uniquely identify states and counties, is provided with each county. Utah's FIPS code is 49, which when combined with any county code would be written as 49XXX. In the FIPS code column in the table below, each FIPS code links to the most current census data for that county. There were ten counties in the Territory of Utah that were absorbed by other states or Utah counties.

More than 1,500 East Prussian places were ordered to be renamed by 16 July 1938, following a decree issued by Gauleiter and Oberpräsident Erich Koch and initiated by Adolf Hitler. This resulted in the elimination, Germanization, or simplification of a number of Old Prussian names, as well as those Polish or Lithuanian origin. Other areas of the Third Reich were affected. Placenames in Masuria were renamed prior to 1938, indeed before the Nazi era. In the district of Lötzen 47 percent of all villages had been renamed in the Weimar Republic and another 36 percent after 1933. A systematic renaming campaign was prepared after Koch issued the corresponding order on 25 August 1937. Following this order, the Prussian Ministry of Science and People's Education set up an expert commission led by Mr Harmjanz. Members included Mr Ziesemer, Mr Falkenhayn and Max Hein. Affected were names of villages, water bodies and cadastral districts. In some counties up to 70% of the placenames had been changed by 16 July 1938.

After World War II the local populace was expelled. The modern Polish names were determined by the Commission for the Determination of Place Names; the names invented in 1938 remain in official use in Germany. A similar Germanization of place names was carried out in other regions of the Third Reich in Silesia. There, 1088 place names in the Oppeln region were changed in 1936 359 in the Breslau area and 178 in the Liegnitz area between 1937 and 1938. In the portion of Upper Silesia which after World War I had become part of the Second Polish Republic, most places had two locally used names, a German one and a Polish one, after 1922, Polish authorities made the Polish variants the "official" names. During World War II, renaming occurred in occupied/annexed territories, because the Nazi government felt that "foreign language names for places constitute a national threat and may lead to mistaken world opinion in regard to their nationality". Areas affected included Polish areas annexed by Nazi Germany, e.g. Upper Silesia and the area near Poznań. and Alsace, as well as Czechoslovakia
