Precision in insights, depth in data
TGI has earned its reputation as trusted partner for brands, products, and media looking to navigate South Africa’s dynamic and complex consumer landscape, with 75% of the top 50 advertisers, media owners, and agencies in the country subscribing. Spanning all socio economic segments, TGI’s extensive survey footprint ensures a deep understanding of consumer behaviour across all income groups – from emerging middle classes to affluent households.
Unlike traditional income profiling methods, which often succumb to response bias, TGI leverages the GTI Neighbourhood Lifestyle Index (NLI). This lifestyle-based profiling method delivers a verified, nuanced understanding of income segments, replacing unreliable claims with trustworthy data.
"By focusing on lifestyle-based profiling rather than direct financial disclosures, TGI delivers a richer, more accurate gauge of income segments. This method not only enhances reliability but ensures decisions are based on verified, not merely claimed information," says Maria Petousis, executive: TGI & Benchmarks at Ask Afrika.
Inclusive representation, unmatched coverage
In a diverse landscape like South Africa, TGI stands out for its inclusivity. The survey captures a realistic cross-section of society, with a sample design that represents the full spectrum of income levels.

Income levels in South Africa have shifted significantly in recent years. What was once considered the 'top' income segment now includes a broader range, spanning moderately average to lower-income consumers. TGI’s historic top 30% – represented by Neighbourhood Lifestyle Index (NLI) groups 4 to 10 – covers consumers from the lower emerging middle class to affluent segments. These higher-end consumers comprise 40% of TGI’s sample, ensuring strong representation.
In addition, TGI provides extensive coverage of NLI 1 to 4, delivering a truly inclusive survey that captures all socioeconomic groups across South Africa in communities 8,000+. With an average household income of R5,800 – 46% above the national average – TGI strikes a balance, accurately representing middle- and upper-income households without neglecting the critical insights from lower-income groups, which often hold significant market value due to their volume.
TGI’s unparalleled depth is evident in its coverage of:
- Seven media types
- 570+ product categories
- 8,000+ brands
- 300+ unique attitude statements
- All income groups
The Power of Face-to-Face Engagement
Data quality is only as good as the methods used to gather it. While many rely on telephonic or online interviews, TGI opts for face-to-face data collection. Though more resource-intensive and costly, this approach delivers richer, more reliable insights, ensuring that decisions are built on a solid foundation.
“Our meticulous approach to sampling underlines our commitment to quality. Despite the inherent challenges of any sampling method, TGI’s strategies are designed to minimise bias, providing a more accurate reflection of the market. This commitment to superior sampling underscores our dedication to delivering data you can trust,” Petousis adds.
