People have lived on the small atolls that make up the Central Caroline Islands, now part of the Federated States of Micronesia, for over a thousand years. Micronesia, as it is commonly referred to, is made up of four mountainous states: Kosrae, Pohnpei, Chuuk, and Yap, with hundreds of small raised coral atolls. Yap is considered still to retain much of its cultural heritage. Life on these remote, outlying islands could for some, especially those from more developed countries, prove lonely and isolating, if not downright difficult. For one thing, the typical size of these atolls is around 2.6 square kilometers (1 square mile) with an average population of 200. Being surrounded by the vast Pacific, they appear on maps as nothing more than tiny dots in the deep blue ocean.
