Answer: Indonesia

Archipelagos are chains, clusters, or collections of islands that make up a geographic region. Many archipelagos are part of larger nations, such as New York City (which is both part of the bigger New York State and then the United States) or the numerous islands off the coast of Greece. Other times, the entire nation itself is an archipelago, as is the case with island nations like New Zealand and the Maldives.

The largest of such archipelago nation states, however, is Indonesia—both by area and population. Located in between the Indian and Pacific oceans, Indonesia has more than 17,000 islands with 735,358 square miles (1,904,569 square kilometers) of land and approximately 275 million citizens.
