Fact Check: "Indonesia has over 17,000 islands."

What We Know

Indonesia is recognized as the world's largest archipelagic state, comprising a vast number of islands. According to various sources, the number of islands in Indonesia is reported to be over 17,000. Specifically, the Law No 9/1996 on Maritime Territory of Indonesia officially lists 17,508 islands within its territory (Wikipedia). However, other surveys have reported varying figures, such as 13,466 islands from a geospatial survey conducted between 2007 and 2010 (Wikipedia), and 18,307 islands according to an earlier survey in 2002 (Wikipedia). As of 2023, the Geospatial Information Agency has named 17,024 islands published in the Indonesian Gazetteer (Wikipedia).

Additionally, other sources corroborate that Indonesia has an estimated over 17,000 islands, with some estimates suggesting numbers as high as 18,307 (Travel Continuously, Indonesia Sentinel). The discrepancies in the counts arise from different definitions of what constitutes an island, including considerations of tidal islands that may appear or disappear with changing tides (Wikipedia).

Analysis

The claim that "Indonesia has over 17,000 islands" is supported by multiple reliable sources. The official count of 17,508 islands is backed by Indonesian law, which provides a strong legal basis for this number (Wikipedia). Furthermore, the Geospatial Information Agency's report of 17,024 islands adds to the credibility of the claim, as it reflects recent data collection efforts (Wikipedia).

However, it is important to note that the number of islands can vary based on the criteria used for counting. For instance, the inclusion of tidal islands can significantly alter the total count. The CIA World Factbook also aligns with the figure of 17,508 islands, which further validates the claim (Wikipedia).

Sources such as Indonesia Sentinel and Travel Continuously provide additional context and estimates that reinforce the assertion that Indonesia indeed has over 17,000 islands. While some sources report lower numbers, these are often based on different methodologies or definitions, which is a common issue in geographical surveys.

Conclusion

Verdict: True
The claim that "Indonesia has over 17,000 islands" is accurate based on multiple sources, including official government records and credible surveys. The variations in island counts can be attributed to differing definitions and methodologies, but the consensus supports the assertion that Indonesia comprises a significant number of islands, well above 17,000.
