1. ZAMBIA CENSUS MAPPING PRESETATION
First Presentation: Session 09

2. Presentation Outline Background to 2020 mapping 2010 census mapping
Issues taken into consideration for the 2020 census mapping
Methodology
Cost benefits of investing in geospatial technology
Census geographic hierarchy
Key Issues for consideration

3. Background – What is a Population and Housing Census
A Population and Housing Census can be defined as the process of collecting, processing and disseminating basic socio-demographic and housing information of every individual within the area of interest – usually a country. The main phases of a census are:
Pre- enumeration Cartography
Enumeration
Data Processing
Analysis and Dissemination

4. Background – What is a Population and Housing Census?
What is a Pre-enumeration cartography?
During pre-enumeration cartography the entire country is sub-divided into small areas of land, usually referred to as enumeration areas (EAs), each one big enough for an interviewer to handle during the period of enumeration (usually 7-14 days). EA size typically varies between households in the rural areas and 150 to 200 households in the urban areas.
Pre- enumeration cartography
Enumeration
Data Processing
Analysis and Dissemination

5. 2010 Census mapping Use of GPS hand held devices
Use of topographic sheets at different scales was used for the majority of the country
Images where used only in provincial head quarters and some towns (5m resolution)
The digitising of the maps was done from HQ

6. Enumeration map on 50,000 sheet

7. Enumeration map on 100,000 sheet

8. Enumeration map on satellite image (5m)

9. Key issues in consideration 2017-2020 mapping
Technology
Imagery at 1.5m in the rural areas and 50cm in the urban areas
Mobile mapping
Methodology
Workflow management

10. Methodology
In the 2017 census mapping exercise will introduce a census mapping software called Smart Client. Smart client for Census is a client-server solution specifically designed for census mapping applications.
WEB-based Client-Server GIS software solution that enables different “users” to log into the system in order to execute the tasks allocated to them.
The step-by-step pre-enumeration census mapping methodology is executed and managed using SmartClient for Census.
Each user can only execute the tasks applicable to his/her role and within the “Production Unit(s)” assigned to him/her at a given moment in time.
Client-specific progress reports
The Software has online and offline functionality – key requirement
Production unit is a ward

11. Hierarchy of workflow Census mapping manager Office Supervisor (OS)
Fieldwork Team Leader (FWTL)
Fieldwork Tablet Operator (FWTO)
Counter

12. Roles and responsibilities
1 Census mapping manager
Coordinate the entire mapping exercise
Consolidate provincial reports
Ensure the smooth flow of work at National level
2 Office Supervisor (OS)
Create a list of FWTL and FWTO associated with each fieldwork team.
Allocate wards to FWTLs
Accept completed PU’s from FWTLs
Validation and quality assurance of data received from the field;
EA map creation;
Creation of other maps required by the census (Enumeration); and
Printing of maps

13. Roles and responsibilities
3 Cartographer/Fieldwork Team Leader (FWTL)
Receive wards(s) allocated to him/her by the OS;
Allocate (2010) EAs within the ward(s) allocated to him/her to the FWTO;
Approve the work submitted by the FWTO per (2017) EA;
Edit 2010 EA boundaries to create the 2017 EAs per ward;
Submit completed Wards to OS for approval.
4 Mapper/Fieldwork Tablet Operator (FWTO)
Online:
Receive EA(s) allocated to him/her by the FWTL;
Offline:
Verify/edit/update existing Points of Interest (PoIs) within the allocated EAs through physical visits;
Capturing of all PoIs with attribute information for all PoIs that are not already in the system.
Upload work done to SmartClient Server
Submit work completed (EAs) to FWTL for approval.
The FWTO will operate mainly in the field. The FWTO will be issued with a Trimble Yuma 2 Field tablet computer. The FWTO will be the only Smart Client user that will be able to work online as well as offline. The online tasks differ from the offline tasks and can be summarised as follows:

14. Roles and responsibilities
5 Assistant mapper/Counter
Identifying boundaries in an EA
Conduct a quick count of households in the EA
Identify POI and verify the 2010 POI
Suggest boundaries for the EAs that might need to be delineated

16. Costs and benefits 1 Pre- census activities
BENIFITS 1
Pre- census activities
K 94,345,550 (US$12,579,407)
Capacity building
Procurement of office equipment(software and hardware) 2
Pilot Census mapping
K 538,450 (US$71,793)
Evaluate all aspects of census mapping operation 3
Mapping phase activities
K55,396,820 (US$7,386,243)
Provides a basis for the main census logistic planning 4
Enumeration Areas demarcation
K 7,695,000 (US$ 126,000)
Creation of new EAs with ideal household population 5
Post Census EA verification
K3,632,000 US$(484,267).
Verification and checking for correctness of the EAs created 6
Post census GIS analysis
Production of census atlas, thematic maps, census frame and small township by population report
10% of the newly created areas will b sampled for verification
The cost for post census GIS analysis has been deliberately left out because it will be part of the census analysis, report writing and printing cost.

17. Census Supervisory Area Standard Enumeration Area
Census Geographic Hierarchy
Province
District
Constituency
Wards
Consideration for defining the national census geography hierarchy and enumeration area level database
As give above work load for urban and the rural area must be evenly distributed 80 to 120 in the rural areas and 150 to 200 in urban areas
Census Supervisory Area
Standard Enumeration Area

18. Institutional framework mapping
Mapping technical Committee
Surveyor General (Chair)
Officers from surveyor generals office
Officers from Electoral Commission of Zambia (ECZ)
Officers from Local Government and housing
Officers from University of Zambia
Officers National Centre for Scientific Research
CSO Directorate
Census manager and deputy census manager
Geographic Information Office
The mapping technical committee will be formed chaired by the surveyor general and it will include people from other ministries and organisation
Technical members from different intuitions are brought on board to insure quality of work as well as involve experts to from various fields to contribute

19. Challenges
Luck of national coordination among intuitions on the geographic standards.
Luck of investment in GIS
Inconsistent updating of geographic data base
