What is a TGI?

TGIs, or Target Group Index, are a set of consumer research tools and datasets used primarily in marketing and media planning to understand audience demographics, behaviors, and preferences. TGIs provide detailed insights into consumers' lifestyles, media consumption, purchasing habits, and attitudes, enabling businesses to target their advertising and product strategies more effectively. These data sets are commonly used by marketers, advertisers, and media agencies to make data-driven decisions and optimize campaign performance.
