The document discusses the use of Computer-Assisted Personal Interviewing (CAPI) technology in agricultural censuses, highlighting its advantages such as cost reduction, improved data quality, and real-time monitoring. It provides examples of CAPI implementation in countries like Indonesia and Tanzania and outlines various CAPI products available, including CSPro and Open Data Kit. The document also emphasizes the increasing adoption of IT technologies in agricultural censuses for efficient data collection and operational monitoring.
Use of Technology for field data capture and compilation : Technical Session 17
- 1. Regional Roundtable on World Programme for the Census of Agriculture 2020 Bangkok, Thailand 19-23 September 2016 Use of Technology for field data capture and compilation Technical session 17 Michael Rahija Global Strategy (main author) Jairo Castano Senior Statistician Leader, Agricultural Census and Survey Team FAO Statistics Division
- 2. Overview of CAPI: description, advantages, disadvantages, products on the market Overview of Survey Solutions features Country examples: Indonesia and Tanzania Overview
- 3. Computer Assisted Personal Interview (CAPI) software allows recording responses on a computer or tablet instead of paper. What is CAPI?
- 4. • Easier Survey Management • Reduced variables costs (No transport costs, no storage costs, no printing costs, no data-entry costs) • Reduced time from data collection to analysis and reporting • Higher quality data (Enforced skip patterns, validation conditions, look-up tables) What are the advantages of CAPI?
- 5. Novel question types Geo reference, photos, barcodes scanning (for national IDs) Closer field monitoring Export paradata for monitoring activities during interviews (e.g. start & end time) Almost real time export of micro data export Easier to implement changes to questionnaire No need to send questionnaires back and forth to field What are the advantages of CAPI?
- 6. High fixed cost Can be reduced by using for multiple surveys Requires more preparation time – programming and testing questionnaire, procurement Time savings on back-end from no data entry compensates Many times requires connectivity Risks can be reduced by using 2 sim cards, back- up paper questionnaires, etc. What are disadvantages of CAPI?
- 7. Census and Survey Processing System (CSPro) Developed by the US census bureau and funded primarily by USAID. Widely used, but lacks survey management tools and requires programming knowledge. FREE + programming costs Open Data Kit (ODK): Core developers at UoW – Dpt. Of Computer Science. Open-sourced, funded partially through donations of users. FREE+ programming costs My Survey Solutions: Development supported by the GS, and first version released in 09.2013. Closed source, but integrates data management tools, and requires little to no knowledge of programming. FREE CAPI Products
- 8. • Global Strategy has implemented surveys on small sample surveys in Tanzania, Indonesia, and Jamaica • World Bank in partnership w/ NSOs have implemented surveys reaching 200K respondents in Malawi, 400K in Uganda, and 2.7 million in South Africa. FAO and Survey Solutions
- 9. User friendly survey management system built right into the software. Survey designer that requires NO programming skills Cloud based data storage and transfer Geo references questions (holding location) Can accommodate any type of question User-friendly Android application for data entry Survey Solutions Features
- 10. Documentation on every part of the system available E-learning course to be available later this year (13 modules) Data export available in SPSS and STATA formats. DDI compliant metadata automatically generated. Automatic paradata tabulation for field monitoring *DDI: Data Documentation Initiative, an int’l standard for describing statistical data Survey Solutions Features (cont’d)
- 11. • BPS with technical assistance from the Global Office of the GS implemented multiple agricultural surveys in 2 provinces using SuSo. • Data was collected on around 400 households. • At the end of the project, BPS purchased 2,000 tablets and is scaling up CAPI to 7 provinces. Country Experience - Indonesia
- 12. In the Agricultural Census 2013, the country: • Used “Sonore” tablets (Chinese made, special order) for data collection instead of traditional paper questionnaires to improve efficiency of field operation; • Used Web Application for monitoring progress of the field operation (in real time) at Headquarters and Local offices Country Experience – Thailand
- 13. Country experiences on use of CAPI, CATI, CASI and GPS technologies in census Country name Year of census CAPI/GPS/PDA/CATI/CASI Estonia 2010 CAPI, CASI France 2010 CAPI Latvia 2010 CAPI, CATI,CASI, Malta 2010 CAPI Poland 2010 CAPI, CATI,CASI Slovenia 2010 CAPI, CATI Lithuania 2010 CASI Netherland 2010 CASI Iceland 2010 CASI Austria 2010 CASI Finlanda 2010 CASI Suedia 2010 CASI, CATI Mozambique 2009/2010 CAPI, GPS Venezuela 2008 CAPI, GPS Argentina 2008 CAPI Colombia 2014 CAPI Brazil 2006 CAPI Mexico 2007 CAPI Canada 2011 CASI USA 2012 CASI Australia 2011 CASI Jordan 2007 CAPI Thailand 2013 CAPI Iran 2014 CAPI Countries are using more and more IT technologies in agricultural censuses for: data collection (CAPI, CASI, CATI); identification of location for the field operation of each enumerator (GPS); monitoring the progress in field operations on the web in real time .
