In the Foster-Greer-Thorbecke class, along with FGT(Q) and FGT(I), poverty computes FGT(<a) with a =Q.5, 1.5,
2, 2.5, 3, 3.5, 4, 4.5, 5. In the Clark-Hemming-Ulph class, poverty computes GHU(∕3) with β =Q.1, Q.25, Q.5, Q.75, Q.9.
Syntax
poverty varname Weeihht] [if exp] [in range] [, line(#) gen(,newvarname) select-options]
aweights and fweights are allowed.
Options
line(#) specifies the value of the poverty line. If # is set to —1, the poverty line is computed as half the median of varname.
If # is set to —2, it is computed as two-thirds the median of varname. Default is —1.
newvaewvaename) creates the new variable newvarname and sets it to 1 for all observations identified as poor (i.e., observations
for which varname is below the specified poverty line) and Q for observations identified as non-poor. neevarname is set to
missing for observations with missing varname or not included by the if in statements.
select-options are options used to select the indices to be computed. It can be any of the following (multiple selections are
allowed, see examples below):
