The island nations are all very small in land area, some only as large as a single district of Taipei (see table). Their material resources are also limited, so that except for fish most of their food and daily necessities must be imported.
這些島國面積都很小，有的甚至只有台北市的一個區或一個里大；資源也有限，大部分不是珊瑚礁，就是火山島，除了漁產外，食物及生活用品多靠進口。
