Abemama has an area of 27.37 square kilometres and a population of 3,299 as of 2015. The islets surround a deep lagoon. The eastern part of the atoll of Abemama is linked together by causeways making automobile traffic possible between the different islets.

The Gilbert Islands are a chain of sixteen atolls and coral islands in the Pacific Ocean, about halfway between Papua New Guinea and Hawaii. They constitute the main part of the nation of Kiribati.
