Alaska's Unorganized Borough is so vast it would be America's largest state

Cultures · Published 10 October 2026 Swipe more like this →

In short: Alaska rejects the traditional American county model, opting instead for a unique system of boroughs. Yet, over half the state remains outside these organized structures. This massive, government-free expanse, known as the Unorganized Borough, is so expansive that it dwarfs Texas and California, functioning solely as a statistical designation.

When Alaska drafted its state constitution, delegates intentionally moved away from the conventional county systems found elsewhere in the United States. Instead, they established a tiered model of organized boroughs, each with varying degrees of legislative authority. These range from Unified Home Rule boroughs, which possess broad powers, to First and Second Class boroughs, which must navigate specific legal or voter-approved requirements to exercise non-area-wide functions. Currently, there are 19 such organized boroughs, which house the majority of the state's population.

The remaining land, which covers over 970,500 square kilometers, is officially termed the Unorganized Borough. Despite its name, this is not a borough at all; it is simply the portion of Alaska not included in any organized municipal structure. Because this region lacks a local government, residents often rely directly on the state for essential services, such as law enforcement provided by the Alaska State Troopers and educational funding. As of the 2025 Census estimate, approximately 75,441 people, or 10% of the state's population, reside within these vast, unorganized reaches.

To manage statistical data across this immense territory, the U.S. Census Bureau divides the region into 11 census areas. These areas, which roughly align with election districts, exist exclusively for data collection and presentation purposes. The number of these areas has fluctuated over time; for instance, there were 12 census areas during the 1980 census. As new boroughs incorporate, these boundaries are adjusted or eliminated. While these census areas are treated as county equivalents for federal record-keeping, they possess no independent governing authority, highlighting the unique administrative landscape of the nation's largest state.
