Arun Kumar, former professor at Jawaharlal Nehru University, observed that the two indices are crucial because the headline retail inflation figure does not accurately represent a large segment of the rural population, given their distinct consumption patterns. Moreover, to compensate MGNREGA workers for inflation, the rural development ministry calculates the wage rate each financial year based on changes in CPI-AL, which then applies from April 1.
“Low-income people, especially in rural areas, spend most of their earnings on food, which is why CPI-AL has a disproportionately high weighting for food items. While the current index, based on 1986-87, is obsolete, we still need a different index to compute inflation as experienced by these sections of the population,” he added.
