Demographic Surveillance
This dataset contains rounds 10 to 71 of demographic surveillance data covering the period from 1 April 1989 to 31 December 2013. One round of data collection took place annually from 1989 to 1998, after which there were four rounds that took place annually through to 2008, then 3 rounds annually.
The Farafenni Health and Demographic Surveillance System (Farafenni HDSS) is located 170 km from the coast in a rural area of The Gambia, north of the River Gambia. It was set up in 1981 by the UK Medical Research Council Laboratories to generate demographic and health information required for the evaluation of a village-based, primary health care programme in 40 villages. Regular updates of demographic events and residency status have subsequently been conducted every 4 months. The surveillance area was extended in 2002 to include Farafenni Town and surrounding villages to support randomized, controlled trials. With over three decades of prospective surveillance, and through specific scientific investigations, the platform (population = 50 000) has generated data on: morbidity and mortality due to malaria in children and during pregnancy; non-communicable disease among adults; reproductive health; and levels and trends in childhood and maternal mortality. Other information routinely collected includes causes of death through verbal autopsy, and household socioeconomic indicators. The current portfolio of the platform includes tracking Millennium Development Goal 4 (MDG4) attainments in rural Gambia and cause-of-death determination.

Coverage
The Farafenni HDSS is located between latitudes 13 and 14 N and longitudes 15 and 16 W, extending 32 km to the east and 22 km to the west of Farafenni. Farafenni town (2012 population 25000) is situated in the North Bank Region of The Gambia and is 170 km in-land from the capital, Banjul. The HDSS was initially made up of two clusters of villages and hamlets to the east and west of Farafenni town. Communities within a 10 km radius were excluded because the initial task of the platform was to assist in an evaluation of the impact of the village-based PHC programme on child and maternal morbidity and mortality with a particular focus on the role of malaria. The surveillance area was expanded in July 2002 to include Farafenni town and its satellite villages. This new segment was designated the urban demographic surveillance area (DSA) despite the satellite villages being very similar to the rural ones, distinguishing it from the initial surrounding clusters of rural villages.
The survey covered all resident population.

Fieldworkers operate in a team of 6 supervised by a Field Supervisor. The Supervisor conducts supervisory and quality control visits and reviews fieldworkers' data collection. A Field Coordinator oversees all data collection and supervision activities.
The initial census was conducted in 1981 and surveillance procedures adopted between 1983 and 1989 are described in the published profile of the Farafenni HDSS.A change in data collection and management procedures in 1989 required fieldworkers to visit every compound under surveillance at least once every quarter to update the survival and residency status of every resident. Resident village reporters, volunteers recruited and trained on the recording of demographic events within their villages, keep records of births, deaths and migrations in and out of their villages.
