Fact Check: "Indonesia has more than 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 total number of islands in Indonesia is often cited as being around 17,000. Specifically, the 17000 Islands project states that Indonesia is an archipelago of more than 17,000 islands, highlighting the country's rich cultural and linguistic diversity. Furthermore, the List of islands of Indonesia indicates that the number of islands ranges from approximately 17,000 to 18,000, depending on the criteria used for counting.

The Indonesian government has officially recognized 17,508 islands as per Law No 9/1996 on Maritime Territory of Indonesia, while other surveys have reported varying figures due to different methodologies and definitions of what constitutes an island. For instance, a geospatial survey conducted between 2007 and 2010 reported 13,466 islands, and another survey in 2002 suggested there could be as many as 18,307 islands (List of islands of Indonesia). As of 2023, the Geospatial Information Agency has named 17,024 islands, which further supports the claim that Indonesia has more than 17,000 islands.

Analysis

The claim that Indonesia has more than 17,000 islands is substantiated by multiple credible sources. The 17000 Islands project, which focuses on Indonesia's cultural diversity, aligns with the general consensus found in geographical surveys. The List of islands of Indonesia provides a comprehensive overview of the varying estimates, noting that the official count is 17,508 islands, while other estimates range from 13,466 to 18,307 islands. This discrepancy arises from different definitions of islands, such as including tidal islands that may only be visible at low tide.

The reliability of these sources is generally high, as they are based on official government data and reputable geographical studies. However, it is important to note that the number of islands can fluctuate due to natural changes in geography, such as erosion and sediment deposition, which can affect the visibility and classification of certain landforms.

Conclusion

Verdict: True
The claim that Indonesia has more than 17,000 islands is accurate based on a variety of sources, including government data and geographical surveys. While the exact number may vary depending on the criteria used for counting, the consensus supports the assertion that Indonesia is home to a significant number of islands, exceeding 17,000.
