figures for the regencies in 2010, 2020 and mid-2021 are given below. The provincial capital is not on Sumba Island, but in Kupang on West Timor. Culture Sumba has a highly stratified society based on castes. This is especially true of East Sumba, whereas West Sumba is more ethnically and linguistically diverse. The Sumbanese people speak a variety of closely related Austronesian languages and have a mixture of Austronesian and Melanesian ancestry. The largest language group is the Kambera language, spoken by a quarter of a million people in the eastern half of Sumba. Twenty-five to thirty percent of the population practices the animist Marapu religion. The remainder are Christian, a majority being Dutch Calvinist with a substantial minority being Roman Catholic. A small number of Sunni Muslims can be found along the coastal areas. Sumba is famous for ikat textiles, particularly very detailed hand-woven ikat. The process of dyeing and weaving ikat is labor-intensive and one piece can take months to prepare. Development and living standards Sumba is one of the poorer islands of Indonesia. Health A relatively high percentage of the population suffers from malaria, although the illness is almost eradicated in the west part of the island. Infant mortality is high. Water Access to water is one of the major challenges in Sumba. During the dry season, many streams dry up and villagers depend on wells for scarce supplies of water. Many villagers have to travel several kilometres several times a day to fetch water. It is mainly the women and children who are sent for water, while the men are at work. The Sumba Foundation has been active in raising sponsorship to drill wells in villages and attempting to reduce poverty on the island. As of February 2013, the Sumba Foundation were responsible for 48 wells and 191 water stations, a supplying 15 schools with water and sanitation, and reducing malaria rates by some 85%. Electricity Electricity mainly comes from diesel generators. New projects include 3 MW Bayu wind power plant (PLTB) in Kadumbul, East Sumba by PT Hywind. Another is the Bodo Hula Biomass Power Plant (PLTBm), West Sumba. 1 MW capacity. Other existing renewable electricity projects involve solar PV and micro-hydroelectricity.
