    Demographic Surveillance
    Series Information

    This dataset contains rounds of 1 to 17 of demographic survillance data covering the period from 1 Sep. 2007 to 31 Dec. 2015. Two rounds of data collection took place every year execpt in 2007 whereby only one round of data collection was done from Sep. to Dec. 2007 (for four mounths). This might give you an infilated indicators particularly on birth rate, sex ratio, and life expectency. In each round an update of all individuals in the system was done in addition to the regular checks for events that change the population structure.
    Abstract

    Kersa Health and Demographic Surveillance System (Kersa HDSS) is located in Kersa district of eastern Hararege, Oromia region, Eastern Ethiopia. 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.

    Kersa 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.

    Coverage

    Geographic Coverage

    Kersa district of eastern Hararege, Oromia region, Eastern Ethiopia
    Universe

    Resident household members of households resident within the demographic surveillance area. Inmigrations are defined by iteration to become resident, but actual residence episodes of less than 180 days are censored. Outmigrants are defined by iteration to become resident elsewhere, but actual periods of non- residence less than 180 days are censored. Children born to be resident women are considered resident by default irrespective of actual place of birth.

    The dataset contains the events of all individuals ever resident during the study period (1 Jan 2008 to 31 Dec 2014).

    Supervision

    Field workers operate in teams of 4 to 6 and were supervised by one supervisor. Supervisors conduct supervised visit and quality control visits and review fieldworker's data collection.
    Data Collection Notes

    Enumerators were trained immediately prior to the baseline collection and then refresher training was conducted for one week every other round. New filed workers received standardized one week training and four weeks on job training prior to appointment as independent data collector. Data entry staff received filed work training in addition to training in the use of data entry programs.

    Data processing

    Data Editing

    On data entry data consistency and plausibility were checked by 455 data validation rules at database level. If data validaton failure was due to a data collection error, the questionnaire was referred back to the field for revisit and correction. If the error was due to data inconsistencies that could not be directly traced to a data collection error, the record was referred to the data quality team under the supervision of the senior database scientist. This could request further field level investigation by a team of trackers or could correct the inconsistency directly at database level.

    No imputations were done on the resulting micro data set, except for:

    a. If an out-migration (OMG) event is followed by a homestead entry event (ENT) and the gap between OMG event and ENT event is greater than 180 days, the ENT event was changed to an in-migration event (IMG).
    b. If an out-migration (OMG) event is followed by a homestead entry event (ENT) and the gap between OMG event and ENT event is less than 180 days, the OMG event was changed to an homestead exit event (EXT) and the ENT event date changed to the day following the original OMG event.
    c. If a homestead exit event (EXT) is followed by an in-migration event (IMG) and the gap between the EXT event and the IMG event is greater than 180 days, the EXT event was changed to an out-migration event (OMG).
    d. If a homestead exit event (EXT) is followed by an in-migration event (IMG) and the gap between the EXT event and the IMG event is less than 180 days, the IMG event was changed to an homestead entry event (ENT) with a date equal to the day following the EXT event.
    e. If the last recorded event for an individual is homestead exit (EXT) and this event is more than 180 days prior to the end of the surveillance period, then the EXT event is changed to an out-migration event (OMG)

    In the case of the village that was added (enumerated) in 2006, some individuals may have outmigrated from the original surveillance area and setlled in the the new village prior to the first enumeration. Where the records of such individuals have been linked, and indivdiual can legitmately have and outmigration event (OMG) forllowed by and enumeration event (ENU). In a few cases a homestead exit event (EXT) was followed by an enumeration event in these cases. In these instances the EXT events were changed to an out-migration event (OMG).
