Paradise In Peril: Hawaiʻi’s Shrinking Population And Energy Crisis

While Hawaiʻi has long been marketed as paradise, the numbers tell a different story. The state lost 2,132 residents in fiscal 2025, dropping its population to 1,432,820. That makes five out of the last six years of decline. Roughly 22,500 people have packed up and left since the 2020 Census. Only Vermont is shrinking faster on a percentage basis. Paradise, it turns out, has an exit door.

The bleeding is mostly domestic. A net 8,876 residents fled to other U.S. states last year alone. Over five years, about 60,000 more people left Hawaiʻi than arrived from the mainland.

Who’s leaving? Young local families, mostly. They can’t afford to buy a first home, so they chase less-expensive pastures on the mainland. Hard to blame them. High taxes, crushing regulatory burdens, and land cost manipulation through Ali’i trust systems have made housing brutally unaffordable. Low wages don’t help either. The Grassroot Institute of Hawaii, a nonprofit policy think tank, has urged the 2026 Legislature to refrain from passing new taxes, fees, or regulations that would worsen the affordability crisis.

International migration isn’t picking up the slack. It actually dropped from 6,588 in fiscal 2024 to 4,768 in fiscal 2025. The Census Bureau also revised its 2023 estimate sharply downward, from 11,893 to 6,588. Anti-immigration policy shifts may be contributing. Either way, the small trickle of foreign arrivals can’t offset the flood heading to the mainland.

The demographic picture is getting weird. Seniors now outnumber kids. The percentage of residents over 65 climbed from 19.9% to 21.5%, while those under 18 slipped to 20.3%. Average family size shrank from 3.40 to 2.85. The people moving in tend to be retirees. The people moving out tend to be workers. That’s not a recipe for economic vitality.

The consequences are already showing up. High school graduation classes are projected to shrink 33% by 2041. Businesses and government agencies can’t fill positions despite a 2.2% unemployment rate. That’s not low unemployment to celebrate. That’s a labor shortage screaming for attention. These shifting demographics are reshaping local economies and hollowing out the community structures that once held neighborhoods together.

The workforce is evaporating while the population ages in place. Every revised Census estimate has moved the numbers further downward. Hawaiʻi isn’t just losing people. It’s losing the specific people it needs most to function.
