The income ratio data highlights the widening income gap in India over time. The top 10% consistently earned a significantly higher share of the national average, ranging from 297% to 386%, with a peak in the mid-2010s, coinciding with the full impact of economic liberalization. This reflects the concentration of wealth among the wealthiest segments during periods of economic growth.

In contrast, the bottom 50% of the population consistently earned below the national average, with their income ratio decreasing from 44% in the 1950s to just 46% in 2022-23. This decline illustrates how the poorest have increasingly been left out of the benefits of economic expansion. The middle 40%, while earning slightly above the national average, showed limited upward mobility, with their income ratio fluctuating between 110-117%. The data emphasizes the growing disparity and marginalization of lower-income groups, despite overall economic growth.
