Alaska is a state in the Western United States on the northwest extremity of North America. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with a population of 736,081 as of 2020—more than quadruple the combined populations of Northern Canada and Greenland. Approximately half of Alaska's residents live within the Anchorage metropolitan area. The state capital of Juneau is the second-largest city in the United States by area, comprising more territory than the states of Rhode Island and Delaware. The former capital of Alaska, Sitka, is the largest U.S. city by area.
Alaska was occupied by various indigenous peoples for thousands of years before the arrival of Europeans. The state is considered the entry point for the settlement of North America by way of the Bering land bridge. The Russians were the first Europeans to settle the area beginning in the 18th century, eventually establishing Russian America, which spanned most of the current state. The expense and difficulty of maintaining this distant possession prompted its sale to the U.S. in 1867 for US$7.2 million (equivalent to $133 million in 2020), or approximately two cents per acre ($4.74/km2). The area went through several administrative changes before becoming organized as a territory on May 11, 1912. It was admitted as the 49th state of the U.S. on January 3, 1959.
While it has one of the smallest state economies in the country, Alaska's per capita income is among the highest, owing to a diversified economy dominated by fishing, natural gas, and oil, all of which it has in abundance. United States armed forces bases and tourism are also a significant part of the economy; more than half the state is federally owned public land, including a multitude of national forests, national parks, and wildlife refuges.
The indigenous population of Alaska is proportionally the highest of any U.S. state, at over 15 percent. Close to two dozen native languages are spoken, and Alaskan Natives exercise considerable influence in local and state politics.
The name "Alaska" was introduced in the Russian colonial period when it was used to refer to the Alaska Peninsula. It was derived from an Aleut-language idiom, which figuratively refers to the mainland. Literally, it means object to which the action of the sea is directed.
Located at the northwest corner of North America, Alaska is the northernmost and westernmost state in the United States, but also has the most easterly longitude in the United States because the Aleutian Islands extend into the Eastern Hemisphere. Alaska is the only non-contiguous U.S. state on continental North America; about 500 miles (800 km) of British Columbia (Canada) separates Alaska from Washington. It is technically part of the continental U.S., but is sometimes not included in colloquial use; Alaska is not part of the contiguous U.S., often called "the Lower 48". The capital city, Juneau, is situated on the mainland of the North American continent but is not connected by road to the rest of the North American highway system.
Alaska has a longer coastline than all the other U.S. states combined.
Alaska has more than three million lakes. Marshlands and wetland permafrost cover 188,320 square miles (487,700 km2) (mostly in northern, western and southwest flatlands). Glacier ice covers about 28,957 square miles (75,000 km2) of Alaska. The Bering Glacier is the largest glacier in North America, covering 2,008 square miles (5,200 km2) alone.
There are no officially defined borders demarcating the various regions of Alaska, but there are six widely accepted regions:
The most populous region of Alaska, containing Anchorage, the Matanuska-Susitna Valley and the Kenai Peninsula. Rural, mostly unpopulated areas south of the Alaska Range and west of the Wrangell Mountains also fall within the definition of South Central, as do the Prince William Sound area and the communities of Cordova and Valdez.
Also referred to as the Panhandle or Inside Passage, this is the region of Alaska closest to the contiguous states. As such, this was where most of the initial non-indigenous settlement occurred in the years following the Alaska Purchase. The region is dominated by the Alexander Archipelago as well as the Tongass National Forest, the largest national forest in the United States. It contains the state capital Juneau, the former capital Sitka, and Ketchikan, at one time Alaska's largest city. The Alaska Marine Highway provides a vital surface transportation link throughout the area and country, as only three communities (Haines, Hyder and Skagway) enjoy direct connections to the contiguous North American road system.
The Interior is the largest region of Alaska; much of it is uninhabited wilderness. Fairbanks is the only large city in the region. Denali National Park and Preserve is located here. Denali, formerly Mount McKinley, is the highest mountain in North America, and is also located here.
Southwest Alaska is a sparsely inhabited region stretching some 500 miles (800 km) inland from the Bering Sea. Most of the population lives along the coast. Kodiak Island is also located in Southwest. The massive Yukon-Kuskokwim Delta, one of the largest river deltas in the world, is here. Portions of the Alaska Peninsula are considered part of Southwest, with the remaining portions included with the Aleutian Islands.
The North Slope is mostly tundra peppered with small villages. The area is known for its massive reserves of crude oil and contains both the National Petroleum Reserve-Alaska and the Prudhoe Bay Oil Field. The city of Utqiaġvik, formerly known as Barrow, is the northernmost city in the United States and is located here. The Northwest Arctic area, anchored by Kotzebue and also containing the Kobuk River valley, is often regarded as being part of this region. However, the respective Inupiat of the North Slope and of the Northwest Arctic seldom consider themselves to be one people.
More than 300 small volcanic islands make up this chain, which stretches more than 1,200 miles (1,900 km) into the Pacific Ocean. Some of these islands fall in the Eastern Hemisphere, but the International Date Line was drawn west of 180° to keep the whole state, and thus the entire North American continent, within the same legal day. Two of the islands, Attu and Kiska, were occupied by Japanese forces during World War II.
Alaska is not divided into counties, as most of the other U.S. states, but it is divided into boroughs. Many of the more densely populated parts of the state are part of Alaska's 16 boroughs, which function somewhat similarly to counties in other states. However, unlike county-equivalents in the other 49 states, the boroughs do not cover the entire land area of the state. The area not part of any borough is referred to as the Unorganized Borough.
The oil and gas industry dominates the Alaskan economy, with more than 80% of the state's revenues derived from petroleum extraction. Alaska's main export product (excluding oil and natural gas) is seafood, primarily salmon, cod, Pollock and crab.
Employment is primarily in government and industries such as natural resource extraction, shipping, and transportation. Military bases are a significant component of the economy in the Fairbanks North Star, Anchorage and Kodiak Island boroughs, as well as Kodiak. Federal subsidies are also an important part of the economy, allowing the state to keep taxes low. Its industrial outputs are crude petroleum, natural gas, coal, gold, precious metals, zinc and other mining, seafood processing, timber and wood products. There is also a growing service and tourism sector. Tourists have contributed to the economy by supporting local lodging.
Alaska has few road connections compared to the rest of the U.S. The state's road system, covering a relatively small area of the state, linking the central population centers and the Alaska Highway, the principal route out of the state through Canada. The state capital, Juneau, is not accessible by road, only a car ferry. The western part of Alaska has no road system connecting the communities with the rest of Alaska.
Many cities, towns and villages in the state do not have road or highway access; the only modes of access involve travel by air, river, or the sea.
The MV Tustumena (named after Tustumena Glacier) is one of the state's many ferries, providing service between the Kenai Peninsula, Kodiak Island and the Aleutian Chain.
Alaska's well-developed state-owned ferry system (known as the Alaska Marine Highway) serves the cities of southeast, the Gulf Coast and the Alaska Peninsula. The ferries transport vehicles as well as passengers. The system also operates a ferry service from Bellingham, Washington and Prince Rupert, British Columbia, in Canada through the Inside Passage to Skagway. The Inter-Island Ferry Authority also serves as an important marine link for many communities in the Prince of Wales Island region of Southeast and works in concert with the Alaska Marine Highway.
In recent years, cruise lines have created a summertime tourism market, mainly connecting the Pacific Northwest to Southeast Alaska and, to a lesser degree, towns along Alaska's gulf coast. The population of Ketchikan for example fluctuates dramatically on many days—up to four large cruise ships can dock there at the same time.
Anchorage and, to a lesser extent Fairbanks, is served by many major airlines. Because of limited highway access, air travel remains the most efficient form of transportation in and out of the state.
Perhaps the most quintessentially Alaskan plane is the bush seaplane. The world's busiest seaplane base is Lake Hood, located next to Ted Stevens Anchorage International Airport, where flights bound for remote villages without an airstrip carry passengers, cargo, and many items from stores and warehouse clubs.
