New data shows Kauai Only County in Hawaii with Population Growth in Decade’s First Half

Recent census data reveals that Kauai County was the only county in Hawaii to experience population growth in the first half of the decade. While other counties in the state witnessed stagnation or declines in their population numbers from 2020 to 2025, Kauai stood out with a modest rise. Experts attribute this growth to factors such as increased tourism, improved infrastructure, and a surge in new businesses and job opportunities attracting residents. In contrast, counties like Honolulu faced challenges like high living costs and urban congestion, which may have contributed to population decreases or slowed growth. Understanding these trends is crucial for local policymakers and businesses as they plan for future development. The insights from this census could drive strategic initiatives to bolster growth in areas lagging behind. This detailed analysis underscores the diverse growth patterns across Hawaii’s counties.
