<h1>Non-response by high-income groups threatens representative survey data; collaborative strategies seek to improve participation and data quality.</h1> Non-response by affluent segments, notably high-income households, gated communities, and high-rise societies, poses a material risk to the integrity and representativeness of national sample surveys. NSSO is convening a multi-stakeholder Brainstorming Session to diagnose non-response trends, assess effects on survey quality, and develop targeted measures-including technological solutions, RWA engagement, and strengthened data privacy practices-to increase participation and secure more representative data for policymaking.
