4 1.INTRODUCTION Censuses in 1962, 1974, and 1984 Results were 1.1, 1.5 and 2.1 millions, respectively. Estimated population is 3.6 million No census for last 24 years due to 14 years of civil crisis Next census planned in March 2008 Census preparatory activities started/on-going Census field mapping work started in March this year

5 2. OBJECTIVES OF CENSUS MAPPING To provide maps for census enumeration To construct an updated master sampling frame To develop a geo-referenced spatial database on statutory boundaries, EAs, localities and social amenities Provide a basis for GIS analysis and dissemination of the census results Develop capacity in Census mapping/GIS

13 6.CARTOGRAPHIC FIELD WORK Contacting the local administration Listing administrative units and localities Map updating (administrative boundaries and other features) Labeling/naming features correctly Recording the location of key feature using GPS coordinates Preparation of GPS Sketch Maps Use of local guides

14 6. CARTOGRAPHIC FIELD WORK cont. Delineation of EAs in Rural Areas EAs must be within a clan Quick count of household in the locality Demarcation of Enumeration Areas each containing households An enumeration area may comprise of:  Several localities put together  A whole locality  Part of a locality (one locality divided into several enumeration areas).

15 6. CARTOGRAPHIC FIELD WORK cont Delineation of EAs in Urban Areas EA must be within a Zone Structure Numbering and Household Listing Demarcation of Enumeration Areas each containing households EA boundaries following physical features Showing as many features as possible Plotting names of household heads on either side of the EA boundary

16 6. CARTOGRAPHIC FIELD WORK cont. Numbering of Enumeration Areas on the EA maps and control forms EA01, EA02, EA03, EA04, EA05, EA06, EA07, EA08, EA09, EA10, EA11, EA12, EA13. Creation and Numbering of Supervision Areas on the maps SA 1 = EA01, EA02, EA03, EA04 SA 2 = EA05, EA06, EA07, EA08, EA09 SA 3 = EA10, EA11, EA12, EA13.
