Simple Spatial Surveying Method (S3M) survey in Sudan

Background: This survey was carried out in all 18 states of Sudan by the Federal Ministry of Health and UNICEF with technical support from Valid International and funding from DFID (Department for International Development). Data collection took place during June/July 2013 for 14 states and in November 2013 for the remaining 4 states (Khartoum, Red Sea, South and West Kurdufan).

The survey used the Simple Spatial Survey Method (S3M), an area based sampling methodology that uses maps for selection of sample points. This methodology was chosen in order to be able to map results and produce results for small areas. For this survey, the size of the area for which results where available was approximately 187km², and results were therefore available at locality and sub-locality level.

Objective: The objective of the survey was to obtain data for basic health, WASH and nutrition indicators for small areas (at sub-locality level) to allow mapping of results to show geographical areas of highest need and ‘hot-spots’ to enable better targeting of existing interventions and will inform program expansion. The survey inclusion of health and wash indicators was aimed at facilitating better integrated programing that is necessary for the reduction of child mortality and reduction of stunting. Overtime, these indicators are key in measuring impact of child survival programs, such as tracking increases in improved sanitation coverage overtime, or reduction in prevalence of diarrhea.

It was the intention of this survey to quantify results for small areas and to show the variation over space. For this reason results were presented at locality level only and have not even aggregated into national level results.

Data Collection: Data was collected in all states. However it should be noted that some areas were inaccessible due to insecurity. This affected parts of Central Darfur, South Darfur and East Darfur in the Darfur Region, as well as the southern-most parts of West Kordofan, South Kordofan and Blue Nile states. Areas not accessed for data collection are clearly shown on all maps as a grey shaded area and are all towards the south of the country. It should be noted that in some localities, some sample points were accessible when others were not. In this case results are presented for the locality with a note that it is only part of the locality. The area represented can be seen on the maps.

Results: data and maps presented are classified into three groups of low, medium and high for every indicator. Cut-offs used for each indicator are based on international public health recommendations or national program targets. Green color on the maps indicates a ‘good’ situation (as determined by the cut-offs used), yellow indicates ‘acceptable’ and red indicates a ‘poor’ situation.

All results for every indicator have been mapped. Results clearly show the geographic areas in highest need for all indicators measured. A total of 59 indicators were measured. All national results maps are presented in the full report, together with results for every indicator at locality level. Table 1 is a table of results for 18 core indicators at locality level. Reports at state level contain more detailed state level heat maps.
