Demographics
Tuālāuta County was first recorded beginning with the 1912 special census. Regular decennial censuses were taken beginning in 1920. Between 2010–2020, Tuālāuta was the only county in American Samoa to experience a population increase. The population here increased by 9.4 percent, while American Samoa as a whole experienced a 10.5 percent population decline. This large increase was largely due to a 57 percent population growth in the village of Mapusagafou. Population growth also occurred in Faleniu (2.9%) and in Tāfuna (0.5%). Population declines were seen in Pava'ia'i (−13.8%), Malaeimi (−11.5%), 'Ili'ili (−3.8%), and in Vaitogi (−1.9%).
