ASTHO supports the U.S. territories and Freely Associated States to improve population and community health. ASTHO's members include the chief health officials of the five U.S. territories and three sovereign nations that have entered into Compacts of Free Association with the United States, which are collectively referred to as the Insular Areas or Island Jurisdictions.
U.S. Territories
- Puerto Rico
- U.S. Virgin Islands
- American Samoa
- Commonwealth of the Northern Mariana Islands
- Guam
Freely Associated States
- Federated States of Micronesia
- The Republic of the Marshall Islands
- The Republic of Palau
Providing public health services in remote islands in the Pacific and the Atlantic is often more costly than in the states. Due to differences in services configuration, eligibility for federal funding and programs, population health needs, and increased susceptibility to climate crisis, their policy needs are complex and often substantially different than those of the states. Given the uniqueness of each jurisdiction, we work to ensure our resources and technical assistance are tailored to their needs.

ASTHO also manages two committees that supports policy efforts in the insular area jurisdictions. The Insular Areas Affairs Subcommittee provides a forum for ASTHO’s insular area island members to exchange information on policy challenges and solutions. The Island Insular Areas Workgroup aims to work with federal and non-profit partners to improve administrative, procedural, or programmatic policies that impact the insular areas island jurisdictions.
