  1. 2010 Integrated e-Census Architecture in Korea Oslo, 18-20 May, 2009 Korea National Statistical Office

  2. Introduction I e-Census system for 2005 II Integrated e-Census system for 2010 III Supplement IV

  3. Introduction I 1. Significancesof a Census 2. Methodological change in Censuses

  4. 1. Significance of a Census Indicators that show the history of a nation Showing the current nation’s picture Basis for policy making 1/12

  5. 2. Methodological change in Censuses • Extend the registration census concept(administrative and registry data) • Target Internet survey participation rate up to 30% • Use the ICR extensively • Improve the IT infra and applications of 2005 Census 2010 • Introduce a registration census concept • Use ICT fully : Web-based data capturing system • The first Internet survey(0.9% households) and data collecting 2005 • Traditional Census : Enumerators visited all households • Decentralized data input and edit 2000 2/12

  6. e-Census system for 2005 II • What’s done in 2005 e-Census • Workflow e-Census system • 3. 2005 e-Census’s Suggestion

  7. Household structure changed • Dual-income households • Elderly households • One-person households Reduced respondent’s burden Increased economical efficiency 1. What’s done in 2005 e-Census Solutions Challenges Development of information technology • Introduce registration census concept • Pilot project of Internet survey Non-response rate increased & Difficulty in traditional Census Strengthening privacy protection • Outsourcing • Apply New ICT(Web) 3/20 4/12

  8. 2. Workflow e-Census system HousingDB Industry/occupation classification coding Cyber training for enumerators Address DB KOSIS DB Credit ratings agencies ICR GIS DB Enumeration districtDB Data Data Data Data Special features Other Systems Population and Housing Census Data Processing System General public • Biz part : preparation, data processing and compilation & analysis. • Interface part : portal, data processing and Internet survey mgt. • Connecting systems : individual authentication, ICR for institution’s ED, Auto-Coding system, Housing DB etc. Census Biz Systems Interface Systems Census Preparation System e-Census Portal • District information • Enumerator information • Household list Staff Census Data Processing System Main data Processing System • Enumerator information • Questionnaire data • Household list Other Office Compilation and analysis Internet survey Management 5/12 CommunicationInfrastructure C/S MiddlewareInfrastructure SMS sending solution Email sending solution DBMS

  9. 2. 2005 e-Census’s Suggestion Business perspective Infrastructure perspective 2005Census 2005Census • One-time use • Insufficient security • Internet circuit overload • Substitute temporary(civil) network for governmental network ＊MPLS VPN • Tight work schedule - All work should be done in a year • Questionnaire settlement delayed 2010 Census 2010 Census • All preparation and system development started in 2009 • Pilot survey fully launched • - ICR input and Internet survey test • - Imputation & editing test • Multi-time use • Advanced security • - Apply a logical & physical security • Bandwidth extension 6/12

  10. Integrated e-Census system for 2010 III • Differences between 2005 and 2010 • Directions of 2010 system • 2010 Architecture • e-Census system

  11. 1. Comparision 2005 and 2010 2010 e-Census 2005 e-Census • Web-based architecture inputted by local enumerators(decentralized) • One-time use • ICR method, Build Internet survey-oriented architecture • Reuse resources of population Census • on 2010 Agriculture/Forestry/Fishery, 2011 Economy census . . . 10/12

  12. 2. Directions of 2010 e-Census architecture Two way of input method Stable Infrastructure • WEB, Goal for 30%, Internet survey • ICR, Using the ICR extensively Principle of system reuse & interoperability Efficiency by maximizing the utilization of IT assets • Improve 2005 e-Census’s resources • Interoperability to following censuses Security strengthening for data protection General-purpose survey management User -friendly application development • System reuse and interoperability for 3 main Censuses • (Population and Housing, Agriculture/Forestry/Fishery, Economy) 7/12

  13. 3. 2010 Architecture(1) Users SMS/Email sending SMS sending Email sending Special features Internet survey errors Edit & Imputation system Assign unique numbers to participants Define edit rules • For the accurate Internet survey • - Feedback system (SMS or E-mail) for erroneous data • 080 toll-free telephone service system for those who give up filling out questionnaires • For the rapid Internet survey • Automate e-questionnaire design process • Participation, survey input and edit functions concurrently Internet survey management Reflect input and edit rules Questionnaire design Encourage respondents who give up responses to fill out questionnaires Local governments /Branch Offices Participant management Authentication of family members staying in other regions 080 Internet survey participation Searching for passwords Internet survey input Internet survey participants Internet survey edit KNSO DATA provision DATA storage Reference to administrative data Administrative data DB Internet survey DB 8/12

  14. Agriculture, Forestry and Fishery Census Economy Census 3. 2010 Architecture(2) Special features Integrated e-Census system • Common functions reused • - Online survey management system • - Cyber training • - Internet survey • ICR input system • E&I system • Infrastructure reorganization for the following Censuses Population and Housing Census Internet survey/ Public relations contents Respondents Input and edit Edit & imputation Internet survey Cyber training Register management Input/edit Integrated edit ICR input Integrated e-Census System Input & edit Enumerators Register Input status Edit status Training status Reusing Application Progress status/ Operation team Online survey management Infrastructure Reuse KNSO • WEB Server 2 • each server 7 partition • WAS Server 2 each server 4 partition • DB Server 2, each server 6 partition • WEB Server 2 • each server 4 partition • WAS Server 2 each 2 partition • DB Server 2,1 Full Partition, another 3 partition Reorganization 2010 E-Census 2011EconomyCensus IBM P595 IBM P595 9/12

  15. 4. e-Census System(Summary) System Design System Operation 1. Reinforce a registration census concept 1. Apply the virtualization technologies 2. System development is outsourced to IT expertise associate 2. Maximize resource utility by partitioning technology 3.Build a reusable system 3. Reallocate real time resource dynamically 4. Automate data collection processes : Internet + ICR 4. Reorganize the servers by survey period 5. Automate the editing & imputation process 5. Duplex configuration to network and system failures 11/12

  16. Supplement IV e-Questionnaire design

  17. e-Questionnaire design Administrative data Meta DB Internet survey DB Edit & imputation Editing rule Future Work Questionnaire design Internet survey input • Improve the Internet survey system continuously • Wizard function will be reinforced • One-stop services will be realized General respondents Survey items management Complete and Sample questionnaire By age By educational attainment Survey items Response code Survey items, code information Item Character-istics Screen Character-istics Questionnaire for institutions Internet Foreigners HTML publication Individual input Batch input Survey template Input & editing rule By respondent (Complete and sample survey form) Questionnaire for foreigners Institutions Special district Institutional district Reference to responses Multi-languages support(English et al) < e-Census survey architecture > 12/12
