Defining a New Somali National Sampling Frame

Project overview

Traditionally, a country’s census is used to create the sample frame for household surveys. However, years of conflict in Somalia made carrying out a census prohibitive. In addition, a nationally representative sampling frame in Somalia is still absent. Defining a national sampling frame requires knowing the spatial distribution of settled areas and the density of people within those areas. However, no current high-resolution maps exist in Somalia for settled areas. This project aimed to create innovative geospatial techniques to create automatic national sampling frames in Somalia. The project was led by Flowminder and funded by World Bank

Research interests

  • Dr Sarchil is a Senior Research Fellow within the WorldPop research group (https://www.worldpop.org) in close collaboration with multiple organizations across the world, whose activities combine research and enterprise. He designs innovative research ideas using big datasets such as remote sensing to improve traditional methods in the application of national population sampling frames for low- and middle-income countries and in agriculture. 

Collaborating research institutes, centres and groups

WorldPop

We develop and implement open, robust and peer-reviewed geospatial methods. These are used for mapping population distributions, demographics and dynamics, with a principle focus on low and middle income countries.
