Region 9

Map of Region 9 States and Territories


The Region 9 Office, based in San Francisco, California, serves Arizona, California, Hawaii (HI), Nevada, American Samoa (AS), the Commonwealth of the Northern Mariana Islands (MP), the Federated States of Micronesia (FM), Guam (GU), the Republic of the Marshall Islands (MH), the Republic of Palau (PW) and more than 157 federally-recognized tribes including the Navajo Nation—the largest tribe in the U.S.

Region 9 shares a border with Mexico and encompasses nine time zones including the International Date Line. Region 9 is diverse in population (California has 40 million people compared to the Republic of Palau with 20,000 people), geography (rural and urban), languages (44% of Californians speak a non-English language at home), and unique demography (Hawaii is the only place in the world where there is no majority group). Given its rich regional diversity, a health equity lens is applied to all regional work across the spectrum of public health, science, environmental justice, and the health impacts of climate change.

Region 9 holds a steadfast commitment to addressing the needs of disproportionately affected populations and the equitable distribution of public health services and immunizations through a prevention-based model. In doing so, ORHO in Region 9 leads the way through partnership, innovation, resource prioritization, and a collective support to the communities most in need via a comprehensive public health “systems” approach.
