• Today is the last day of the NSSO Consumer Expenditure Survey (NSSO-CE) for the period July 2017 to June 2018.
• The NSSO-CE surveys form the basis of calculations of absolute poverty, an important and political economic variable in India.
• The 2017/18 survey indicates that absolute poverty in India, according to the official Tendulkar poverty line, is in the low single digits.
THE POVERTY LINE
• If household per capita consumption is below an arbitrary level of consumption, it is classified as poor.
• While economists have had obtuse debates about the level of this line, it is arbitrary. One such line, adopted by government of India, is the Tendulkar poverty line.
World Bank poverty line
• The World Bank is in the business of poverty, and for decades has attempted to objectively define an absolute poverty line. Co-incidentally, its absolute poverty line is always identical to the Indian poverty line.
• The only difference being that the Indian poverty line is in Rs per capita per month, and the World Bank poverty line is in PPP$ per day.
• Recently, the World Bank suggested poverty lines for three classes of countries — the poor (PPS 1.9 per person per day, pppd, 2011 prices), lower middle income (PPP$ 3.2 pppd) and upper middle income (PPP$ 5.5 pppd).
• India is no longer a poor country though the poverty industry is dependent on this classification for its existence.
• It’s a lower middle-income country, and should adopt a lower middle income poverty line.
• This poverty line (PPP$ 3.2) is some 68 per cent higher than the Tendulkar line.
WHY 2017/18 POVERTY ESTIMATES WOULD BE AN EYE-OPENER?
• Almost certainly, the poverty rate according to the Tendulkar poverty line — Rs 30 per person per day, pppd, in 2011/12 and estimated as Rs 44 pppd in 2017/18 — will dip to around 4 per cent, or about 50 million poor people. This is too low a poverty line.
• The World Bank suggests a poverty line of 3.2 PPP$ (2011 prices) which translates into roughly a consumption level of Rs 75 per person per day.
• In other words, the absolute poor in India today should be defined as those with a consumption level less than Rs 75 per person per day. This means that, at present, a third of the Indian population is absolutely poor.
SOME TERM ESTIMATES
• Consumption inequality in India has stayed roughly constant for the last 30 years.
• The Gini index — it has a value zero in the utopian economy of all individuals having the same income and value 1 in the world where one person has all the income — of real inequality for consumption in India, in 1983, was 0.3034; in 2011/12, it was 0.3165.
• If it is assumed that consumption inequality has stayed the same since 2011/12, or has not changed much, then the 2011/12 consumption distribution can be used to assess changes in poverty according to different poverty lines.
2. Consumption Recall
• Estimates of household consumption are based on interviews. For different items, the NSSO interview schedule specifies different “recall” periods.
• Until 2004/5, there was Type1 recall: Thirty days for fruits and vegetables, and most other items of consumption, and 365 days for major items of consumption.
• In 2011/12, a new method (Type2) was used where fruits and vegetables (perishables) were based on a recall period of seven days.
• Just this seemingly minor change led to an increase in average consumption of 6 per cent for the same year, and a change in the Tendulkar poverty estimate from 22.2 per cent to 14.9 per cent for the same year.
• Estimation of average consumption growth since 2011/12 is done on the basis of growth in personal consumption expenditures in the national accounts (NA) minus the consumption in the NA that does not accrue to households, for example, estimates of consumption of banking services, consumption by NGOs, etc.
• In addition, the share of consumption (private final consumption expenditures) in NA has increased from 56.2 per cent in 2011/12 to 59.2 per cent in 2017/18.
• All of this adds up to the fact that real average real consumption over the last six years has grown at an average rate of 4.9 per cent per annum, compared to an average growth rate of 3 per cent in the period 2004/5 to 2011/12.
• The 2017/18 data (it is believed) will be based on the Type 2 method, and it is expected that the Tendulkar poverty line will yield a low estimate of 4 per cent.
• According to the 68 per cent higher World Bank middle income (WBMI) line, close to 78 per cent of the Indian population was absolutely poor in 2004/5, a proportion that was brought down to 65 per cent in 2011/12, and 42 per cent in 2017/18.
• However, for Type2 consumption, WBMI line will likely yield an estimate of absolute poverty around 33 per cent in 2017/18.
