Correction: An earlier version misstated statewide diversity values and racial-share ranges, undercounted the groups that grew, mishandled zero-share groups in its rural Shannon calculation, and included numeric and causal context not established by the state enrollment package. This revision uses a zero-safe calculation and limits its findings to fresh package output.

In the Yukon-Kuskokwim Delta, Lower Kuskokwim School District^↗ET enrolls 3,666 students. Of those, 3,537 are Alaska Native. White students number 88, or 2.4%.

Both of these districts are majority-minority. So are 33 others. In total, 35 of Alaska's 53 districts, or 66%, have student populations where white enrollment falls below 50%. That share has held essentially constant for seven years. The state's racial composition is not shifting. It arrived somewhere before the data begins, and it has stayed.

A diversity index that does not budge

The Shannon diversity index, a measure borrowed from ecology that captures both the number of groups present and the evenness of their representation, offers a way to quantify what the enrollment lines show. For Alaska statewide, the index stood at 1.501 in 2019-20. In 2025-26 it was 1.495. The total range across all seven years: 0.009, from a low of 1.493 to a high of 1.501.

For context, a state where every student belonged to one group would score 0. A perfectly even split among seven groups would score 1.946. Alaska sits in between, and it is not moving in either direction.

White students have held between 47.1% and 47.4% of enrollment in every year of the dataset. Native American students have held between 21.0% and 21.7%. Hispanic students: 7.3% to 7.7%. The lines on the chart are so flat they could pass for a calibration test.

Alaska's white share fell just 0.1 percentage points between the first and last years. The state was already majority-minority before the dataset opens in 2019-20, and the proportions locked in.

What is actually changing: absolute numbers

The stability in shares conceals significant losses in absolute enrollment. Alaska lost 3,272 students between 2019-20 and 2025-26. Four racial groups shrank, while three grew.

White students lost 1,880, or 3.1%. Native American students lost 1,353, or 4.9%. Asian students lost 1,180, or 16.2%, the steepest percentage decline of any group. Black students lost 648, a 19.5% drop on a small base of 3,317.

Three groups grew. Multiracial students added 1,170, a 7.3% gain, rising from 16,060 to 17,230. Pacific Islander students added 186, or 4.6%. Hispanic enrollment edged up by 22 students, or 0.2%.

The result is a state losing students across most categories while its overall racial shares changed little.

The multiracial question

Multiracial enrollment recorded the largest numeric gain, but the enrollment package does not identify why a student's reported category changes.

In Alaska, multiracial enrollment peaked in 2024 at 17,345 and then dipped, losing 62 students in 2024-25 and another 53 in 2025-26. Its share still rose from 12.4% to 13.7% over the full period because total enrollment fell faster.

Two Alaskas: a diversity gap of 1.477

The state average masks a structural divide. Anchorage, with 40,688 students, posts a Shannon diversity index of 1.719. No single group exceeds 40% of enrollment: white students hold 39.2%, multiracial 15.8%, Hispanic 12.3%, Native American 10.7%, Asian 9.7%, Pacific Islander 7.8%, and Black 4.4%. Seven groups, all represented, none dominant.

Rural Native districts occupy the other end. Sixteen districts are more than 88% Alaska Native. In Kashunamiut^↗ET, Lower Yukon^↗ET, and Yukon Flats^↗ET, white students number in the single digits or zero. Hydaburg^↗ET, Pribilof^↗ET, and Saint Mary's^↗ET enrolled no white students at all in 2025-26. Across rural Native districts above 80% Alaska Native, the enrollment-weighted Shannon index was 0.242, compared with Anchorage's 1.719.

The gap between Anchorage and these districts widened over the seven-year period. Anchorage's diversity index rose from 1.687 to 1.719, while the enrollment-weighted index for rural Native districts above 80% Alaska Native fell from 0.481 to 0.242. The enrollment package measures that divergence but does not establish its cause.

Other district compositions

Fairbanks^↗ET reported a 54.6% white share and a diversity index of 1.355, below Anchorage's 1.719. Kodiak Island^↗ET reported 45.0% white, 24.1% Native American, and 20.9% Asian enrollment. These records describe district composition; they do not identify the mechanisms behind it.

The count holds, but the students leave

The number of majority-minority districts has held between 34 and 36 every year since 2019-20. No district has crossed the threshold in either direction for more than a single year. The borderline districts, Ketchikan Gateway^↗ET at 50.4% white and Wrangell^↗ET at 47.3%, have bounced around the 50% line without establishing a trend.

Native American enrollment fell from 27,709 to 26,356 over the seven-year window, a loss of 1,353 students, or 4.9%. That decline was proportionally steeper than the white decline of 3.1%.

What frozen diversity actually means

The package data show two developments at once: the state's total enrollment fell, while its statewide racial shares and count of majority-minority districts changed little. White students recorded the largest numeric decline. Black and Asian students had the largest percentage declines, and Native American enrollment fell faster in percentage terms than white enrollment. The data do not support a forecast about how long that balance will persist.
