Place guide
Penghu is represented as the full county archipelago rather than Penghu Main Island. The official inventory covers 90 islands, allowing the area and registered population to remain aligned at county level.
The land total includes inhabited and uninhabited islands but excludes sea area. A fitted outline cannot by itself show ferry connections, bridges or actual travel time.
County-wide density pools residents across the administration and should not be read as the density of each island.
Against Taiwan, Penghu shows the scale of one offshore county within the national total. Against Miyako or Ishigaki, it provides a familiar Taiwanese archipelago reference.
Those two uses are related but not identical, so every comparison repeats the relevant boundary note.
