Interesting insights from the 2025 Hawai‘i Data Book

The state Department of Business, Economic Development and Tourism recently released the 2025 edition of the state "Data Book," the 58th iteration of the comprehensive statistical guide. You can find it free online here.

"DBEDT has published the Data Book since 1962 and it continues to be one of our most frequently praised resources,” DBEDT Director James Kunane Tokioka said in a recent announcement. “I’m often stopped by residents and community leaders who share how valuable the information is for their work and planning. The Data Book helps researchers, businesses, government agencies and local organizations understand Hawai‘i through reliable, accessible data.

"This year’s edition reflects close collaboration between our Research and Economic Analysis Division and partners across federal, state and county agencies, as well as private organizations, to deliver the high‑quality information the public depends on.”

The department says that this year, all tables have been redesigned to meet Americans with Disabilities Act accessibility standards and Excel files are now the exclusive download format.
