Despite no official record of the number of foreigners working
on Koh Tao, there is clearly a significant number (estimated at 300e
400) in the local society. Approximately half of the Thai respondents
who are economically dependent upon dive tourism
indicate that other members of their immediate family also live on the island and work in the dive tourismindustry. Surprisingly, there
was no agriculture or fishery sector reported in the questionnaire
survey. These results can be considered an indicator to determining
the dependency of Koh Tao residents upon the dive tourism
industry.
