Abstract
An analysis of poverty change between 2004–2005 and 2009–2010 is decomposed into the within-group effects of growth, inequality, and population components and the between-group effect on account of changes in population shares. The relatively higher incidence of poverty is not restricted to the known poorer states viz., Chhattisgarh, Assam, Bihar, Madhya Pradesh, Odisha, Uttar Pradesh, and Jharkhand (CABMOUJ, pronounced kab mouj implying when to relax), but also includes regions in some of the better-off states of Andhra Pradesh, Gujarat, and Maharashtra and also in some of the Northeast states. Growth effects having adverse implications on poverty reduction is also observed in some regions of Punjab, Gujarat, and West Bengal among others. Increasing inequality is a matter of concern, particularly in regions comprising some well-known urban centers. Negative effects from population growth subsumed other effects in Northern Bihar, Eastern Gujarat, and Southern Odisha. Shift in population shares point out that people out-migrate from regions, where growth has adverse implications on poverty change. Providing opportunities and improving capabilities of people to take advantage of opportunities made available, particularly in regions where poverty has increased, should be a public policy priority.

Notes
- 1.
In Mishra (2015), the base followed was period 1. At the three broader levels, the components of income growth, inequality, and population effects will remain the same, independent of the base time period. However, with a change in the base period, the specific attribution and interpretation will change when the broader levels are further disaggregated. In particular, the sequence of the (2)–(7) will get reversed.

The results at the aggregate level will differ from Mishra (2015) for two reasons. The calculations and weights in the current exercise are region specific whereas in the earlier exercise they were state specific. Besides, the population used in the current exercise is obtained from the unit level data whereas in the earlier exercise the population from Censuses of 2001 and 2011 were interpolated at the state level.

There were 78 NSS regions in 2004–2005 (61st round) and 88 NSS regions in 2009–2010 (66th round). However, to make them comparable, they were reduced to 74 comparable regions. Details of the 74 regions, as per the 61st round, are given in Appendix.

On inequality , the method proposed is to control for the Lorenz ratio/Gini coefficient. This implies that we control for the distribution that is independent of scale. Hence, it will not control the increasing real gaps at the absolute level. Further, as the inequality was controlled at the regional level, it could change at the state or national level.
