Niakhar Health and Demographic System Surveillance (1962-continuous)

Système de suivi démographique A mettre pour le data set Cet ensemble de données contient les rondes 1 à 16 des données de surveillance démographique couvrant la période allant du 1er janvier 2008 au 31 décembre 2016.

Un recensement initial de référence a été effectué en 1962 pour 8 villages, suivi d'un autre en 1983, lorsque la zone d'étude de Niakhar a été élargie. De 1962 à 1987, les données ont été recueillies au cours de cycles annuels pendant la saison sèche. Les événements démographiques ont été recueillis par les intervieweurs en utilisant une liste imprimée de résidents composés avec leurs caractéristiques. De 1987 à 1997, les cycles sont devenus hebdomadaires en raison de la nécessité d'un enregistrement continu des naissances pour les essais de vaccins. Des recensements annuels ont été effectués pour vérifier la collecte de données, en particulier par rapport à l'entrée et à l'émigration. Des visites de routine ont été menées dans les 30 villages de la zone d'étude tous les trois mois entre 1997 et 2007 et tous les quatre mois entre 2008 et 2012 et tous les six mois depuis. Les entretiens sont effectués avec la tablette PC depuis 2007. Les autopsies verbales sont complétées après chaque tour par du personnel qualifié.

This dataset contains rounds 1 to 16 of demographic surveillance data covering the period from 1 Jan 2008 to 31 December 2016.

An initial baseline census was carried out in 1962 for 8 villages, followed by another one in 1983 when the study area of Niakhar was expanded. From 1962 to 1987, data were collected through annual rounds during the dry season. Demographic events were collected by interviewers using a printed list of compound residents with their characteristics. From 1987 to 1997, rounds became weekly because of the need for continuous birth registration for vaccine trials. Annual censuses were carried out to check data collection, particularly relative to in- and out-migration. Routine visits were conducted in the 30 villages of the study area every three months between 1997and 2007 and every four months between 2008 and 2012 and every six month since then. Interviews are conducted with tablet PC since 2007. Verbal autopsies are completed after each round by trained personnel.

Migration, Mortalité, Fécondité, Population La zone d'étude de Niakhar est située au Sénégal, latitude 14.5ºN et longitude 16,5ºO dans le département de Fatick (Sine Saloum), à 135 km à l'est de Dakar. La zone d'étude de Niakhar couvre 203 kilomètres carrés et se situe dans la zone climatique continental sahélienne-soudanaise. Pendant trente ans, la région a souffert de la sécheresse. Les précipitations annuelles moyennes sont passées de 800 mm dans les années 1950 à 500 mm dans les années 80. Des quantités croissantes de précipitations ont été observées depuis le milieu des années 2000 avec des précipitations annuelles moyennes de 600 mm entre 2005 et 2010.

Members of households reside within the demographic surveillance area. Inmigrants are defined by intention to become resident, but actual residence episodes of less than 180 days are censored. Outmigrants are defined by intention to become resident elsewhere, but actual periods of non-residence less than 180 days are censored, except seasonal work migrants, worker with a wife resident, pupils or students. Children born to 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 1990 to 31 Dec 2013).

The Niakhar HDSS collects for each resident the following basic data: individual, household and compound identifying information, mother and father identification, relationship to the head of household and spousal relationship. From 1983 to 2007, the HDSS routinely monitored deaths, pregnancies, births, miscarriages, stillbirths, weaning, migrations, changes of marital status, immunizations, and cases of measles and whooping cough. For the last 5 years, the HDSS only recorded demographic events related to each resident including cause of death. Verbal autopsies have been conducted after all deaths except for those that occurred between 1999 and 2004 where only deaths for people aged 0-55 years were investigated. The Niakhar HDSS also registers visitors as well as all the demographic events related to them in case of in-migration. Household characteristics (living conditions, domestic equipment, etc.) were collected in 1998 and 2003, and community equipment (schools, boreholes, etc.) in 2003. Economic and environmental data will be collected in 2013. Table 3 presents further details on the data items collected. The Niakhar HDSS interviewers collect data with tablet PCs that are loaded with the last updated database linked to a user-friendly interface indicating the household members and the questionnaire. Daily backups are performed on an external hard drive and weekly synchronizations are scheduled during the round, helping to update the database and check data consistency (i.e. residential moves within the study area or marriages). Applications are Developed in Visual Basic.Net and the database is managed with Microsoft Access.
