Physical Koh Tao area paired with the 2024 Ko Tao subdistrict registered population. The administrative subdistrict also covers very small nearby islands, so density is a close local approximation rather than a headcount confined to the coastline. The ministry report the area comes from is no longer downloadable from its original address; it is cited here because it is where the figure was published, and no replacement official Thai source states an area for the island.
Average administrative density does not describe population distribution in every neighborhood. Compare population definitions and reference dates alongside the numbers.
Place guide
Koh Tao is a compact island with a local subdistrict population that can be separated from the wider Ko Pha-ngan District.
The area is for the physical main island. Ko Tao subdistrict can include tiny nearby islands, so the registered-population density remains a close approximation.
This limitation is much smaller than using the full two-island district total.
Its area sits close enough to Green Island for a useful direct comparison and far below the larger Gulf islands.
Tourism intensity requires visitor and accommodation data beyond registered residents.
