  2. 1 Overview 2 Background 3 Process 4 Major Findings 5 Application of the Results 6 Challenges and Lessons 7 Cooperative Efforts to measure ICT use in AP Region Contents

  3. Multi-stage stratified sampling based on enumeration districts for Population and Housing Census Overview Title Survey on the Computer and Internet Use Sample Eligibility Family members aged 3 or older in about 7,000 households in nationwide sample districts Fieldwork Period June & December (semi-annually) Data Collection Face-to-Face Interview Sampling Method Post-stratification - Households : Province by householder’s age - Individuals : Province by age and sex Estimation

  4. 2002 1999 ~ 2001 - extended the sample eligibility to the aged 6 or older “Survey on the number of Internet users and Internet usage patterns ” - sample eligibility : aged 7 or older 2004 2003 - Included wireless Internet users in Internet users (since Dec) “Survey on the Computer and Internet Usage” 2005 - Extended the sample eligibility to the aged 3 or older (since Dec) Background Survey on ICT use in NIDA has been conducted since 1999 Became official survey by integrating various surveys on ICT use to reduce redundancy and increase efficiency in 2003  only nationwide scale survey on ICT use by households and individuals in Korea

  5. What is NIDA? NIDA(National Internet Development Agency of Korea Non-Profit Statutory Organization founded in 1999 (former KRNIC) Subsidiary to the MIC(Ministry of Information and Communication) in accordance with the Act on Internet Address Resources (July 2004) In charge of allocation & managing Internet address including R&D activities designed to increase the use of Internet in Korea Mission Cooperation with internet-related international organizations R& D of Internet-related subjects Release Internet-related Statistics Technical Support Policy Development ㆍkr DNS Service ㆍAllocation of IP Address as NIR ㆍENUM, RFID, WINC etc.

  6. Related Acts Statistics Act Clause 4 (designation of statistical agencies) : The KNSO Commissioner authorizes designated agencies or statistics according to the request of the related agencies Clause 8 (approval of compiling statistics) : Statistical agency should obtain approval from the KNSO Commissioner prior to research new statistics or revise the approved statistical research Clause 15 (publishing the results) : Statistical agency should submit the results of the survey to the KNSO Commissioner and have consultations before publishing the results Act on Internet Address Resources Clause 9, Art 3 : NIDA shall perform each of the following duties ① Policy research and system improvement regarding Internet Address Resources ③ Production of statistics regarding domestic use of the Internet ④ Support for efficient operation of the Internet and promotion of its utilization

  7. Survey Planning Sampling Design Questionnaire Design Pilot Test Fieldwork Data Processing Publishing the Results Process Coordinate the opinions of MIC and NIDA at the beginning of each year - Make a fundamental plan for the survey MIC finances the survey and NIDA conducts the survey Consult with KNSO prior to making changes on the survey including revision of questionnaire and publishing the results, etc. Commit fieldwork to a professional research company • MIC(Ministry of Information & Communication) • KNSO(Korea National Statistical Office)

  8. Sampling Design Use 10% EDs in the Population and Housing Census  EDs : enumeration districts • Population • : Family members aged 3 or older residing in households • in nationwide sample districts • Multi-stage stratified sampling • Stratify the whole nation into 16 strata(7 metropolitan cities and 9 provinces) • Select the sample districts within each strata (700 sample EDs) • Select 10 households within each sample districts (7000 households)

  9. Questionnaire Design Develop questions reflecting a variety of issues, recent trends and special aspects of Korea’s information society Include recommendations of international bodies including OECD, ITU etc. ex) revised OCED 2004 model questionnaire (DSTI/ICCP/IIS(2005)3/FINAL) • Increase flexibility of the questionnaire • Make Questionnaire’s choices more specific so as to apply data more flexibly • ex) question for Internet user’s definition • Internet user’s definition in Korea : person aged 3 or older who used the wired or wireless Internet at least once in the last month • Conduct the pilot test for 20~30 respondents and check errors of revised questionnaire

  10. Validated data are coded and stored in a computer data file - Encode data in real-time for prompt analysis Analyze and tabulate through a statistical package program Weighted values are obtained by applying a post-stratification method Units of analysis : both households and individuals Fieldwork & Data Processing Fieldwork Fieldwork Period - First half of the year : 1~30, June - Second half of the year : 1~30, December Fieldwork Method : Trained interviewers visited each households and conducted face-to-face interviews Keep the same households interviewed in the previous surveys for the accuracy and stability of the survey (around 75% maintenance rate) Conduct real-time check on interim findings during fieldwork to maintain the stability of data and facilitate the survey - Degree of fieldwork progress & time-series analysis compared with the previous year Data Processing

  11. Publicize within 1 month after fieldwork (January, July) Discuss the results to confirm the reliability of the data with MIC and KNSO before publicity Disseminate the statistics and summarized report through mass media and then publish final report in both Korean and English Provide statistical data in various format - Publications, website(ISIS), Internet Statistics Yearbook/Internet Whitepaper, etc. Publishing the Results http://isis.nida.or.kr

  12. Major Findings (1) • Internet Usage of the aged 6 or older (Those aged 7 or older until December 2001)

  13. Internet Users 33.01million(72.8%) Use only wired Internet 21.39 million(47.2%) Wired Internet Users 32.48 million(71.6%) Use both Wired & Wireless Internet 11.09 million(24.4%) Wireless Internet Users 11.62 million(25.6%) Major Findings (2) Use only Wireless Internet 0.53 million(1.2%)

  14. Research materials for the academics and researchers Sources of news article Application of the Results: Domestic Basic data for policy development of government agencies including MIC, KNSO and so on < IT 839 Strategy (MIC) > < Newspaper (Korea Times) > < TV (KBS) >

  15. Application of the Results : International(1) International Application (1) ITU Internet Indicators (2004)

  16. OECD Key ICT Indicators Publications of OECD Households with access to Internet Households with access to PCs Application of the Results : International(2) International Application (2)

  17. Challenges and Lessons (1) Although sampling errors of statistics for the whole nation are very small, the local ones are relatively large Sample size is planned to be increased to 10,000 households and 25,000 persons from the second half of 2006 Supplementary budget is required to increase sample size more [ Sampling Error of Internet use rate by region (2005. 12) ] (95% confidence level)

  18. Reflect various interests of international or government bodies as the official survey on ICT use Develop and Incorporate new issues in the ICT sector Challenges and Lessons (2) Increase in the number of questions Increased burden for respondents Differentiate the first half questionnaire from the second half of 2006 • Core questions : basic data to represent the status of national internet usage applied time-series analysis including Internet usage rate, Internet access rate, % of household with computers etc.

  19. Challenges and Lessons (3) Difficult to interview with family members in the daytime due to the increase of double-income and single-person households Visit the households after 4 pm or on weekends Increased response refusal due to one’s privacy • Show respondents the supplementary documents : • Official document issued by government (MIC) for asking to cooperate in survey • Interviewer’s identification • Copies of news reported on the results
