A measure of understanding

Methodology

All Global TGI studies follow standardised guidelines and formats, but with the flexibility to fully reflect local market needs and characteristics.  Accordingly some of the methodologies differ slightly to accommodate local requirements.

• In most countries some information is collected face-to-face, with a self-completion questionnaire subsequently left with respondents.  However increasingly online is being offered as an option for respondents.
• Most surveys have an annual release with many providing options for either quarterly or 6 monthly updates.
• Many countries sample individuals from age 15+, however some countries provide information on 10+ or 12+
• Sample sizes vary across countries with the largest being 93,000 in China through to 1,400 in Bahrain.  The mean average sample size is almost 12,000 across the Global TGI surveys.  For individual country samples please select the country from our network.  All TGI data are weighted to match known demographic profiles, and our media measures either constitute national media currency themselves, or are reweighted to match the accepted currency.
• Generally, fieldwork is either continuous or conducted in a couple of waves across the year.
