Study the following information carefully and answer the question given below:
Poverty measurement is an unsettled issue both conceptually and methodologically.Since poverty is a process as well as an outcome many come out of it while others may be falling into it The net effect of these two parallel processes is a proportion commonly identified as the ‘head count ratio’ but these ratios hide the fundamental dynamism that characterises poverty in practice The most recent poverty re-estimates by an expert group has also missed the crucial dynamism In a study conducted on 13,000 households which represented the entire country in 1993-94 and again in 2004-05 it was found that in the ten year period 18.2% rural population moved out of poverty whereas another 22.1% fell into it over this period This net increase of about four percentage points was seen to have a considerable variation across states and regions
