State constitution (United States)
The territories of the United States are "organized" and, thus, self-governing if the United States Congress has passed an Organic Act. Only two of the 14 territories – Guam and the United States Virgin Islands – are organized. One unorganized territory, American Samoa, has its own constitution. The remaining 13 unorganized territories have no permanent populations and are either under direct control of the U.S. Government or operate as military bases.
