The islands are located some 110 kilometers (68 miles) east of Tutuila and are a part of American Samoa, an unincorporated territory of the United States.

Taʻu is the largest of these islands, with an area of 44 km2 (17 sq mi), and it has the highest point of the Manuʻa, at 931 meters (3,054 feet).

Emigration is the consequence of a lack of economic opportunities and a desire of young people to participate in the more modern lifestyle offered on Tutuila (Office of Tourism, 2005).

This journey of the sun is strongly related to traditional beliefs and defines the uniformity of cultural identity across both Samoas.

Yet, the American Samoa Government (ASG) is the largest employer in the islands, with branch offices of each government department: Agriculture, Education, Department of Health, Public Safety & Fire, Port Administration, ASPA, ASTCA, Marine Wildlife Resources, and M&O.

By the 1830s, missionaries transcribed the Holy Bible into the native tongue, adding the letters h, k, and r to accommodate the new sounds from the scriptures.

The spoken language has since adopted a heavy "k" sound that is usually reserved for non-biblical traditional oratory and everyday conversation.

[citation needed] The fauna of the Manu'a Islands reflects a balance of indigenous species and human-introduced animals, shaped by millennia of human activity.

Indigenous birds such as the Pacific pigeon and the Crimson-crowned fruit dove inhabit the forested highlands, while seabirds like the White-tailed tropicbird nest in cliffs.

Marine life is significant, with Ofu’s surrounding reef supporting a variety of mollusks, crustaceans, and fish.

Edible species such as Periglypta reticulata and Tridacna maxima thrive in the coral ecosystem, while Spiny lobsters and reef fish are regularly harvested.

Marine turtles Chelonia mydas and Eretmochelys imbricata are represented in archaeological deposits, indicating historical nesting.

Early Polynesian settlers introduced domestic animals such as pigs, dogs, and rats, which left archaeological traces.

Invertebrate fauna is particularly rich, especially land snails, which serve as key indicators of environmental change.
