Health & Demographic Surveillance Unit

The Health and Demographic Surveillance Unit (HDSU) evaluates the impact of different interventions relating to population, health and socioeconomics. The Unit has two functional sub-units: (1) Health and Demographic Surveillance System (HDSS) and (2) Geographic Information System (GIS). Demographic surveillance in Matlab started in 1966, and the surveillance of health conditions was added in 1978 in one half of Matlab (ICDDR,B service area). The GIS component was initiated in 1994. This system for collecting demographic data on more than 200,000 people for over 40 years is the longest-running demographic surveillance system in the world.
