Small area estimation of prevalence of diarrhoea among under-five children in Bangladesh by combining health survey and census data
The demand for small (local-level) area statistics has increased tremendously, particularly in countries where a decentralised approach to governance and service provision has been adopted. However, most of these countries lack local-level statistics to aid policy decisions and planning. Sample surveys such as the Demographic and Health Survey provide a wide range of invaluable data at the national and regional level but cannot be used directly to produce reliable district-level estimates due to small sample sizes. The small area estimation (SAE) technique overcomes the sample size challenges and can generate representative and reliable estimates at the local (or small area) level by linking outcome of interests that are recorded in survey with auxiliary data from census or administrative datasets. This talk illustrates an application of SAE method to generate district-level estimates of prevalence of diarrhoea among under-five children in Bangladesh by combining Demographic and Health Survey and Population Census data. The diagnostics measures show that the estimates generated by SAE method are precise and robust when compared to the direct survey estimates. In countries where small area statistics are non-existent, SAE techniques could be crucial for designing effective policies and strengthening local-level governance.
