Innovative Data Collection Methods Using Handheld Devices for Census in Bhutan
Exploring the use of handheld electronic devices for census data collection in Bhutan, this approach involves CAPI technology supported by Survey Solutions. Researchers design questionnaires using visual tools and upload them to a central server for distribution to enumerator teams. Survey Solutions components include a Designer, Tester, Synchronization point, Headquarter, Supervisor, and Interviewer. The method offers advantages such as improved data quality, faster data availability, simplified coordination, scalability, and environmental friendliness. However, challenges like Internet connectivity, new data collection concepts, and technical expertise are faced.

Use of handheld electronic devices for census data collection (Bhutan)
BACKGROUND Explored the use of CAPI technology in early 2015 Survey Solutions with the technical support from world bank Can be tailored to the needs of the clients, allowing them to successfully complete simple and more sophisticated projects. The CAPI application runs on every device powered by Android.
Researchers design questionnaires using visual tools and upload them to the central server Questionnaires with no errors are uploaded to the central server HQ distributes the sample lists across teams of enumerators Internet Internet Supervisors monitor the submissions Interviewers synchronize their devices and upload completed questionnaires WiFi WiFi Supervisors assign households to individual interviewers Enumerators repeat interviews if errors are detected Interviewers visit households and collect data
SURVEY SOLUTIONS COMPONENTS Designer - web-based tool to develop the questionnaires, allows collaboration of multiple users Tester - application available from Google (TM) Play for testing the behavior of the questionnaire on a tablet without other infrastructure Synchronization point - data server for access by all users to exchange information and coordinate the survey Headquarter - user and a corresponding component, which conducts global, survey-level actions: manages users accounts, starts a survey, exports the data, etc, and performs the highest level of quality control Supervisor - user and a corresponding component, which distributes the workload between the interviewers, and assures quality of the incoming data Interviewer - user and a corresponding component, which is responsible for conducting the interview and collecting respondent s answers
ADVANTAGES improved data quality speed up data availability simplified routing and survey coordination very scalable Environmental friendly and resource saving
CHALLENGES Internet Connectivity issue New concept of data collection Technical Expertise in hosting servers Electronic devices and technology becomes obsolete after a few years
