The study focused on applying GIS technology to investigate the demographic situation in Sudan during year 2000 and 2004. This includes investigations of the basic environmental indicators and their impacts on population distribution in Sudan at that period. Sudan political map and other thematic maps of the country (produced in 2000 by the UN) together with the population sheets issued for Sudan by UN in 2000, 2001, 2002 and 2004 were used to generate a GIS model for the study area. Based on this model the main demographic indicators were spatially and statistically analyzed. A projected decline in demographic status was remarked. During 2000 and 2004 Sudan was suffering from a general to severe degradation in population activity. This was found to be true in all demographic indicators evaluated in this study. Severe degradation rates were remarked for indicators associated with sex and age. For example a great degradation in sex ratio was taken place in most of the states of the country (in the range of 6.12%. to 73.19%). This degradation reflects a critical situation, where the structure of these indicators can have considerable impacts on the population's social and economic situation, both present in the future. The study also concluded that the population distribution was found to be affected by the average annual rainfall, agricultural activities and geological structures.
