The 2006-07 Sri Lanka Demographic and Health Survey (SLDHS) is the fourth in a series of DHS surveys to be held in Sri Lanka – the first three having been implemented in 1987, 1993 and 2000. Teams visited 2106 sample points across Sri Lanka and collected data from a nationally representative sample of almost 20000 households and over 14700 women age 15-49. The objective of the survey is to provide data needed to monitor and evaluate the impact of population, health, and nutrition programmes implemented by different government agencies. Even though all 25 districts were included at the design stage, the final sample includes only 20 districts as the five districts in the Northern Province (Jaffna, Kilinochchi, Mannar, Vavuniya, and Mullativu) had to be excluded due to the security situation in these areas.
