Example
The use of poverty is extremely simple. Consider the dataset subcvse.dta provided with glcurve in Jenkins and Van
Kerm (1999). We have a (single adult equivalent) household income measure (eqinc) and a variable with the household size
(size). Applying poverty to eqinc (f)weighted by size with the all option returns the whole series of measures computed
over all observations and taking half the median of eqinc as the poverty line.
. poverty eqinc [fw=size] , all
Poverty measures of eqinc
Your selection is made of 200 observations.
The following poverty analysis has been using the 200 non-missing
observations for eqinc in your selection.
The poverty line is set at 134.5 units
(1/2 of median value)

If we are interested only in the headcount ratio, the poverty gap ratio and the Sen index and want to check the sensitivity
of the results against a different poverty line (e.g., two-third of the median), we can type
. poverty eqinc [fw=size] , h pgr s line(-2)
