The coming 12 months are very critical for the political history of Sudan. Two landmark events in the country’s history will take place. In April 2010 Sudan is expected to organise the first multi-party general executive and legislative elections after more than 20 years of authoritarian military rule. In January 2011 the people in Southern Sudan will exercise, in a popular referendum, their right to self-determination and decide on the future of the country. This DRDC report is documenting for some aspects of Sudan’s 5th Population and Housing Census and drawing attention to key areas of weaknesses of the census operation.
