electronic data collection technologies

Introduction
•
The use of electronic data collection technologies with other
geospatial technologies have substantially impacted
considerably on planning, designing and implementing census
and other survey operations
•
before making a decision for the adoption electronic
devices/Internet for census data collection, important
considerations must be made in the planning, preparation and
design stages
•
NSOs have taken advantage of these advance technologies to
modernise these processes, and improve quality and timeliness
of results
Past Processes
•
The last two population censuses in Ghana (2000 & 2010) used PAPI
and scanning technology for data processing
•
Though the results were released faster than it would have been with
the use of typewriters, there were challenges associated with;
1.
Printing of questionnaires ( paper quality, delivery of products,
2. Equipment for scanning (expensive, become obsolete in no time, )
•
Scanned information often have different processes before ascii output is
obtained
•
Takes time and space
•
All these affects the production and effective utilization
of statistics and the goals of a national statistical system-
•
Delays in the release of final census results (between
2-3 years)- affecting planning
•
Over spending of budget lines leading to inability to
undertake some other important planned activities
Past Processes cont’d
The transition process
•
The challenges associated with the use of scanning technology led
to the need for Ghana Statistical Service to search and adopt the
use of electronic devices for data collection which will dramatically
reduce the time lag between data collection, analysis and
dissemination
•
In the 2014 Ghana Demographic Health Survey (GDHS), GSS
introduced the Computer Assisted Field Edits (CAFÉ) technology
where paper questionnaires were used for interviews and later
entered onto a computer in the field. Data files were transferred to
the central office immediately
•
In 2015, GSS conducted a Family Life and Health Survey (DFID,
IDS-UK) where Computer Assisted Personal Interview (CAPI)
technology was used for the first time
•
3 staff were trained at US Census Bureau in the use of CAPI
technology
•
The success of the 2015 household survey (LFS) became the
stepping stone for the adoption of the technology
The transition process cont’d
•
Subsequently, GSS has used tablets for the
•
2015 Ghana Labour Force Survey,
•
GLSS7
listing exercises ,
•
2016 Reproductive Health Commodity Security Survey and
•
GLSS7 main data collection.
•
Plans are also underway for the use of tablets for the
Census of Agriculture to be conducted this year. The pilot
has already been done using tablets.
The transition process cont’d
Moving forward
•
The success of the main field work of the Census of Agriculture
using tablets will further inform GSS as to the ease of using tablets
for large scale surveys.
•
Over 5000 interviewers and supervisors will be involved in the
Census Agriculture.
-Procurement of tablets for the Census of Agriculture is underway.
•
Other preparatory activities for 2020 PHC are ongoing
•
Demarcation
•
Digitizing of EA maps
•
Project document
Other considerations include
•
Initial investment as compared to printing and storage of PAPI
•
Cost of equipment & type of operating system-Android devices and
software compatibility
•
Training of interviewers, supervisors including staff in the team – slightly
more days than using PAPI
•
Communication and connectivity-,– 2 SP cover entire country
•
Data transfer -cloud-based servers
•
Capacity to handle survey
•
Collaboration between DP and IT team for technical assistance and trouble
shooting during system development , testing and fieldwork
Other considerations cont’d
•
Adoption of CAPI technologies enhanced the design of census process
•
Modifications to questionnaire are effected and deployed immediately
•
DB of listed structures and households instead of PAPI
•
No need for mass storage of PAPI
•
Strategies for maximising the benefits of investment
•
Require less space for storage of devices
•
Reuse devices for other intercensal surveys
•
Rent/lease out devices to other institutions.
Challenges so far
•
Malfunctioning of devices in the course of fieldwork , and sometimes
delays in replacement due to distance thus forced to revert to PAPI
•
Some remote areas are without electricity and interviewers have to
travel long distances to charge devices-tablets and power banks.
•
Sometimes difficult to edit work done by interviewers during field
monitoring.
•
Acquiring a tablet which cannot run some modules of the data
management process due to cost vrs sophisticated devices with under
utilized functionalities

Thank you for your attention
The adoption of electronic data collection technologies in Ghana for the 2020 Population and Housing Census has brought significant improvements over traditional methods. This transition process aims to streamline data collection, analysis, and dissemination, reducing time lags and improving the quality and timeliness of results. Previous processes using PAPI and scanning technologies faced challenges leading to delays in census results. The move towards electronic devices like Computer Assisted Field Edits (CAF) is enhancing the efficiency of data collection processes in Ghana.
