How the survey was done
The format was an opinion poll based on 10,073 face-to-face interviews
with children and young people between the ages of 9 and 17, who
are representative of more than 300 million of their peers in the
17 countries and territories that were surveyed.
The survey used the same methodology and questionnaire in all the
countries, making for comparable results. UNICEF's East Asia and
Pacific Regional Office defined the objectives and recommended and
approved both the questionnaire and report formats.
Research International Asia's Thailand office (RIA Thailand) was
responsible for coordinating the research. It briefed the 14 local
agencies involved and acted as a link between them and UNICEF. RIA
Thailand completed recommendations on the questionnaire's contents
and format, translating it back into the original language to ensure
that meaning was preserved, pilot test of the questionnaire in all
17 countries and territories, checking and monitoring fieldwork
and analysing and presenting the regional and country data.
Local research agencies undertook fieldwork and quality control,
questionnaire translation, preparation and printing of the survey
materials, data entry and editing and transmitting of clean data
to RIA Thailand.
The interviews were conducted door-to-door using a probability
sample with stratified cluster sampling to ensure that the results
were representative. The questionnaires were administered in the
child respondents' homes, but without the presence of parents or
other third parties.
In most countries the sample size was 500, with a smaller size
used in Hong Kong (300) and Macao (200) and a significantly larger
size in China (1,900) and Indonesia (1,000). Each survey took an
average of 25 to 30 minutes to complete. The survey has an overall
average sampling error of plus or minus 1.2 per cent.
The survey was supported by UNICEF country offices in East Asia
and the Pacific, the Australian Committee for UNICEF, the Hong Kong
Committee for UNICEF, the Korean Committee for UNICEF and UNAIDS.
