塞内加尔农村地区尼亚哈尔的健康和人口监测系统（HDSS）位于达喀尔以东135公里处。 HDSS 由塞内加尔发展研究所 (IRD) 于 1962 年成立，旨在解决民事登记制度的缺陷并提供人口指标。1962 年至 1969 年间，HDSS 每年对尼亚哈尔地区约 65 个村庄进行跟踪调查。从 1969 年到 1983 年，研究区减少到 8 个村庄，此后 HDSS 扩展到包括其他 22 个村庄，2012 年 1 月覆盖了总共 30 个村庄，人口估计为 43 000 人。因此，尼亚哈尔地区的 8 个村庄已接受人口监测近 50 年，30 个村庄已接受人口监测 30 年。每 4 个月定期记录一次怀孕和免疫接种情况。 HDSS 数据库还包括从具体调查中获得的流行病学、经济和环境信息。从 1962 年到 1987 年，数据通过年度巡查收集。从 1987 年到 1997 年，巡查变成每周一次，随后在 1997 年到 2007 年期间每 3 个月进行一次例行访问，此后每 4 个月进行一次。 HDSS中收集的数据不开放访问，但可以在协作和捐赠的条件下公平共享。
The Health and Demographic Surveillance System (HDSS) in Niakhar, a rural area of Senegal, is located 135km east of Dakar. The HDSS was established in 1962 by the Institut de Recherche pour le Developpement (IRD) of Senegal to face the shortcomings of the civil registration system and provide demographic indicators.Some 65 villages in the Niakhar area were followed annually by the HDSS from 1962-1969. The study zone was reduced to 8 villages from 1969-1983, and from then on the HDSS was extended to include 22 other villages, covering a total of 30 villages for a population estimated at 43 000 in January 2012. Thus, 8 villages in the Niakhar area have been under demographic surveillance for almost 50 years and 30 villages for 30 years.Vital events, migrations, marital changes, pregnancies, and immunizations are routinely recorded every 4 months. The HDSS data base also includes epidemiological, economic, and environmental information obtained from specific surveys. Data were collected through annual rounds from 1962 to 1987. The rounds became weekly from 1987-1997, followed by routine visits conducted every 3 months between 1997 and 2007 and every 4 months since then. The data collected in the HDSS are not open to access, but can be fairly shared under conditions of collaboration and endowment.
