List of U.S. states by population density in the context of "Maine"

Utah is a landlocked state in the Mountain West subregion of the Western United States. It is one of the Four Corners states, sharing a border with Arizona, Colorado, and New Mexico. It also borders Wyoming to the northeast, Idaho to the north, and Nevada to the west. In comparison to all the U.S. states and territories, Utah, with a population of just over three million, is the 13th-largest by area, the 30th-most populous, and the 11th-least densely populated. Urban development is mostly concentrated in two regions: the Wasatch Front in the north-central part of the state, which includes the state capital, Salt Lake City, and is home to roughly two-thirds of the population; and Washington County in the southwest, which has approximately 180,000 residents. Most of the western half of Utah lies in the Great Basin.

Utah has been inhabited for thousands of years by various indigenous groups, such as the ancient Puebloans, the Navajo, and the Ute. The first Europeans to arrive – in the mid-16th century – were the Spanish. Because of the region's challenging geography and harsh climate, it only became a peripheral part of New Spain (and later of Mexico). Even while it was Mexican territory, many of the Utah region's earliest European settlers were from the United States; notable among these were Mormons who were fleeing marginalization and persecution in the United States and arrived via the so-called Mormon Trail. In 1848, after the Mexican–American War, the region was annexed by the U.S., becoming part of the Utah Territory, which included what later became Colorado and Nevada. Disputes between the dominant Mormon community and the federal government delayed Utah's admission as a state: in 1896, after it agreed to outlaw polygamy, it was admitted as the 45th state.

Rhode Island (/ˌroʊd -/ ROHD) is a state in the New England region of the Northeastern United States. It borders Connecticut to its west; Massachusetts to its north and east; and the Atlantic Ocean to its south via Rhode Island Sound and Block Island Sound; and shares a small maritime border with New York, east of Long Island. Rhode Island is the smallest U.S. state by area and the seventh-least populous, with slightly more than 1.1 million residents as of 2024. The state's population, however, has continually recorded growth in every decennial census since 1790, and it is the second-most densely populated state after New Jersey. The state takes its name from the eponymous island, though most of its land area is on the mainland. Providence is its capital and most populous city.

Native Americans lived around Narragansett Bay before English settlers began arriving in the early 17th century. Rhode Island was unique among the Thirteen British Colonies in having been founded by a refugee, Roger Williams, who fled religious persecution in the Massachusetts Bay Colony to establish a haven for religious liberty. He founded Providence in 1636 on land purchased from local tribes, creating the first settlement in North America with an explicitly secular government. The Colony of Rhode Island and Providence Plantations subsequently became a destination for religious and political dissenters and social outcasts, earning it the moniker "Rogue's Island".

North Dakota ( /dəˈkoʊtə/ də-KOH-tə) is a U.S. state in the Upper Midwest, named after the indigenous Dakota and Sioux peoples. It is bordered by the Canadian provinces of Saskatchewan and Manitoba to the north and by the U.S. states of Minnesota to the east, South Dakota to the south, and Montana to the west. North Dakota is part of the Great Plains region, characterized by broad prairies, steppe, temperate savanna, badlands, and farmland. North Dakota is the 19th-largest state by area, but with a population of just under 800,000, the fourth-least populous and fourth-least densely populated. The state capital is Bismarck and the most populous city is Fargo, which accounts for nearly a fifth of the state's population; both cities are among the fastest-growing in the U.S., although half of North Dakotans live in rural areas.

What is now North Dakota was inhabited for thousands of years by various Native American tribes, including the Mandan, Hidatsa, and Arikara along the Missouri River; the Ojibwe and Cree in the northeast; and several Sioux groups (the Nakota, Dakota, and Lakota) in the rest of the state. European explorers and traders first arrived in the early 18th century, mostly in pursuit of furs.

Wyoming (/waɪˈoʊmɪŋ/ wye-OH-ming) is a landlocked state in the Mountain West subregion of the Western United States. It borders Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With an estimated population of 587,618 as of 2024, Wyoming is the least populous state despite being the tenth-largest by area, and it has the second-lowest population density after Alaska. The state capital and most populous city is Cheyenne, which had a population of 65,132 in 2020.

Wyoming's western half consists mostly of the ranges and rangelands of the Rocky Mountains; its eastern half consists of high-elevation prairie, and is referred to as the High Plains. Wyoming's climate is semi-arid in some parts and continental in others, making it drier and windier overall than other states, with greater temperature extremes. The federal government owns just under half of Wyoming's land, generally protecting it for public use. The state ranks sixth in the amount of land—and fifth in the proportion of its land—that is owned by the federal government. Its federal lands include two national parks (Grand Teton and Yellowstone), two national recreation areas, two national monuments, and several national forests, as well as historic sites, fish hatcheries, and wildlife refuges.

Idaho (/ˈaɪdəhoʊ/ ) is a landlocked state in the Pacific Northwest and Mountain West subregions of the Western United States. It borders Montana and Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west; the state shares a small portion of the Canada–United States border to the north with the Canadian province of British Columbia. Idaho's state capital and largest city is Boise. With an area of 83,569 square miles (216,440 km), Idaho is the 14th-largest state by land area. The state has a population of approximately two million people; it ranks as the 13th-least populous and the seventh-least densely populated of the 50 U.S. states.

For thousands of years, and prior to European colonization, Idaho had been inhabited by natives. In the early 19th century, Idaho was considered part of the Oregon Country, an area which was disputed between the U.S. and the British Empire. Idaho officially became a U.S. territory with the signing of the Oregon Treaty of 1846, but a separate Idaho Territory was not organized until 1863, instead being included for periods in Oregon Territory and Washington Territory. The state was eventually admitted to the Union on July 3, 1890, becoming the 43rd state.
