Actually 20,983 people
Methodology
The report is based on data collected from an online survey fielded in 2009. The sample
included 20,893 respondents from NPD’s online consumer panel. Such a large sample
provides an optimal platform for data analysis. The nationally-representative sample
included males and females ages two to 65+. Responses for two- to 12-year-olds were
captured by surrogate reporting where the female parent/guardian age 21+ was asked
to complete the survey with the child at the computer to answer either with or without
the adult female’s assistance.
