How the survey was done
The poll used descriptive and quantitative research of young children
and adolescents in Latin America and the Caribbean. Data was collected
from 11,852 respondents of both sexes between the ages of 9 and
18, during October and November of 1999, using the same methodology
and questionnaire in all 20 countries surveyed. The estimated margin
of error was +/-1.2% relative to the population with a statistical
reliability of 95%.
The opinion survey was comprised of a semi-structured questionnaire,
with both closed questions, where the respondent selects from several
possible answers, that where best corresponds to what he or she
thinks, and open-ended questions, where the respondent gives spontaneous
responses, without orientation or prompting of any kind.
The questionnaire was administered in the child respondents' homes,
without the presence of parents or third parties in order to encourage
the child to answer all the questions freely and candidly.
The sample was non-proportional, stratified by weighting the defined
socio-demographics. The results of the study were weighted according
to the real population and adjusted for each of the demographic
segments considered in the sample.
These demographic parameters included age, gender, urban and rural
residency, as well as the socio-economic status of the household
(high, medium and low socio-economic levels). These measures ensured
an accurate and representative sample.
The poll was conducted by Time Research Chile, which coordinated
the regional institutes involved, namely Marketing Group, Borge
& Associates, Research & Research, Invamer, M.H. & Associates,
Time Research Peru, Ibope Time, MKT, Time Research Brazil, Marketing
Investa and Time Research Argentina.
