South Tarawa has part(s) Betio
Geography
South Tarawa is a string of islets on the atoll of Tarawa, between the Tarawa Lagoon to the north, with a maximum depth of 25 metres (82 ft), and the Pacific Ocean to the south, with a depth of up to 4,000 metres (13,000 ft). The island has been built from sediments from the lagoon.The process of soil accumulation is driven by the dominant easterly trade winds and can be reversed during extended periods of westerly winds during El Niño–Southern Oscillations.These islets are now joined by causeways, forming one long islet on the reef along the southern side of the Tarawa Lagoon. Most of South Tarawa is less than 3 metres (9.8 feet) above sea level with an average width of only 450 metres (1,480 feet).Population
At the time of the 1978 Census, South Tarawa had a population of 17,921 with most residents living in the main population centres of Betio, Bairiki and Bikenibeu. Since Kiribati became independent in 1979, the population of South Tarawa has more than tripled, and now stands at 63,439 people (2020). All of South Tarawa is now urbanised and is effectively one continuous settlement from the northeastern end of the island, Tanaea, to its southwestern end at Betio.
Buota in North Tarawa is connected to the South Tarawa main road and is also growing rapidly.
