It was established in 2007 with the vision of becoming center of excellence in health science research in Ethiopia. It conducts health and demographic surveillance. The major work on the ground are monitoring demographic altering events such as birth, death, and migration; and health related conditions such as pregnancy, immunization, and morbidity. It also conducts verbal autopsy for the deceased to identify causes of death. \n\nKersa HDSS was established in 12 sub-districts of Kersa district, Eastern Hararghe, Oromia Region, Ethiopia. The site is principally rural with three small towns (Kersa,  Weter and Langhe). The baseline census was conducted in 2007 and since then has been updated every six months, with registration of demographic and health events. Data is entered into the HRS-2 relational database. At baseline a total of 10,085 houses, 10,522 households and 50,830 people were registered. The sex ratio and number of persons per household was 1.0 and 5.1, respectively. At the end of 2016 the population was 130,358. Until the end of 2016, 20,935 births and 5,195 deaths were registered, respectively.","coll_dates":[{"start":"2008-01-01","end":"2014-12-31","cycle":"Release Coverage"}],"nation":[{"name":"Ethiopia","abbreviation":"ETH"}],"geog_coverage":"Kersa district of eastern Hararege, Oromia region, Eastern Ethiopia","analysis_unit":"Individual","universe":"Resident household members of households resident within the demographic surveillance area.
