Chakaria Health and Demographic Surveillance Site (CHDSS)
The CHDSS was established in 1999 to assess whether health and demographic changes in an area of Bangladesh were due to secular socio-economic changes or to earlier implemented health intervention programmes. Eight unions (the smallest rural administrative and local government unit in Bangladesh) are covered: Baraitali, Kayerbil, Bheola Manik Char, Paschim Boro Bheola, Shaharbil, Kakara, Harbang, and Purba Boro Bheola. Of these, the last two unions formed the comparison area, and the first six formed the intervention area. The site belongs to Chakaria Upazila, a subdistrict of Cox's Bazar district of Bangladesh. As of 2012, the CHDSS covered over 118,000 individuals across 19,847 households.
