Process
Survey Planning
Coordinate the opinions of MIC and
NIDA at the beginning of each year
Sampling Design
- Make a fundamental plan for the survey
MIC finances the survey and
NIDA conducts the survey
Questionnaire Design
Consult with KNSO prior to making
changes on the survey including
revision of questionnaire and publishing
the results, etc.
Pilot Test
Fieldwork
Commit fieldwork to a professional
research company
Data Processing
Publishing the Results
 MIC(Ministry of Information & Communication)
 KNSO(Korea National Statistical Office)
7
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)
※ Classification criteria used in selecting EDs
: 19 variables including farm/non-farm division, housing characteristics,
education levels, house ownership status, computer and automobile
ownership, population aged 15 or older
8
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
When was the last time for you to use the wired/wireless internet?
⑤ Over 3 months ~ within 6 months
⑥ Over 6 months ~ within 1year
⑦ More than 1 year before
① Never used
② Within a week
③ Over a week ~ within 1 month
④ Over a month ~ within 3 months
 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
9
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
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
10
Publishing the Results
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.

Challenges and Lessons (1)
Large sampling error in local statistics
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

Challenges and Lessons (2)
Increase in the number of questions
Reflect various interests of
international or government
bodies as the official survey
on ICT use
Increase in the number
of questions
Increased burden
for respondents
Develop and Incorporate
new issues in the ICT sector
Differentiate the first half questionnaire from the second half of 2006
First half of the year
Second half of the year
core questions + new issues in ICT sector
core questions + requested questions
from the international and government bodies
 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.
18
Challenges and Lessons (3)
Increase of non-responses
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
