Rote Island’s annual income is not a single fixed number, because it depends on the activity you mean. For seaweed-farming households on Rote Island, one study found that about half of families relied on seaweed farming as their main cash income source, but it did not give one island-wide average income figure.

What the evidence shows

  • The study on Southwest Rote Island says seaweed farming is a major livelihood and that seasonal swings strongly affect household earnings.
  • It also says 50% of households in the studied villages depended on seaweed farming as their primary income source.
  • Because income varies by season, farm size, and whether families have other jobs, a single “annual income for Rote Island” number would be misleading.

Best available estimate

For context, related seaweed-farming families in similar parts of Indonesia can earn around US$5,000 per year, while larger operations can reach US$15,000 per year. That is not an official island-wide average for Rote Island, but it is the closest clear income estimate in the source material you asked about.

Important note

If you meant the island’s total economy or average household income across all residents, the result would need a different source and a more specific definition of “annual income.”
