Link between income and nutrition
As income increases, life expectancy increases.
However there are diminishing returns to income e.g through obesity and other “rich world” diseases
(KNOWN AS PRESTON CURVE)- curve is upward sloping then flattens
Measures of poverty and tool
Tool: poverty line
Measures:
Incidence of poverty: Headcount index
Depth of poverty: Poverty gap
Poverty line
Cut off point separating poor from non-poor.
Absolute poverty line vs relative poverty line
Absolute is earning less than $1.25/2 a day.
Relative is based on average income level e.g in UK it is earning less than 60% of median household income
Choice of poverty line is arbitrary: cost of livings vary as well as different types of deprivation so a number of poverty lines must be estimated.
A good example is Bangladesh having 43.3% below $.125, but 76.5% below $2, so can be misleading.
Poverty lines are static while poverty is dynamic.
Poverty headcount (PH)
Proportion of people below poverty line out of population.
What has been happening with poverty rate trends
Has been falling
Poverty gap
Average gap between the income of the poor and the poverty line, in terms of the poverty line.
Between 0-1
Poverty gap formula
PG= 1/n x (sum of poverty gaps/poverty line)
Z=poverty line
Yi=household income
N=population
Note: if z-yi is a negative number, it means no poverty as household income (Yi) > poverty line
