Why India's Wealth Data Remains in the Dark

• India possesses sophisticated systems to track poverty, but data on the wealthy and the securely well-off is largely absent.
• Traditional income and consumption surveys suffer from underreporting and cultural reluctance to disclose earnings, rendering them ineffective for measuring affluence.
• Asset-based indices, focusing on durable goods, housing quality, and land ownership, offer a more stable and accurate reflection of long-term financial status.

The Data Blind Spot

• Major surveys like the National Sample Survey (NSS) focus on essential goods, failing to capture the consumption patterns of the affluent.
• Even comprehensive studies like the India Human Development Survey (IHDS) struggle with income data due to the tendency of wealthier households to skip or fudge questions.
• The current data vacuum makes it impossible to design equitable tax systems, targeted social programs, or effective climate policies.

The Asset-Index Advantage

• Research by Soumyajit Bhar (2025) demonstrates that a Weighted Asset Index (WAI) is significantly more stable over time than reported income or consumption.
• Unlike income inquiries, questions about asset ownership—such as appliances or piped water—are less socially intrusive and yield more reliable data.
• This approach is particularly effective in rural areas where income is seasonal or informal, providing a clearer picture of permanent economic standing.

Policy Implications of Inequality

• Economists like Thomas Piketty and Lucas Chancel have highlighted the severe lack of data regarding India’s top income earners, which distorts inequality debates.
• Carbon inequality is frequently overlooked in climate discussions, despite the top 20 percent of households accounting for seven times the emissions of the poorest groups.
• Moving toward an "affluence-aware" research framework is essential to understand the relationship between deprivation and privilege, ultimately informing more sustainable and equitable national policies.
