This measure reflects the depth of poverty as well as its incidence. Data showing as 0.5 signifies a poverty gap of less than 0.5 percent.
- Gap at $2 a day > PPP: Poverty gap is the mean shortfall from the poverty line (counting the nonpoor as having zero shortfall), expressed as a percentage of the poverty line. This measure reflects the depth of poverty as well as its incidence. Data showing as 0.5 signifies a poverty gap of less than 0.5 percent.
- Headcount ratio at $1 a day > PPP > % of population: Population below $1 a day is the percentage of the population living on less than $1.08 a day at 1993 international prices. As a result of revisions in PPP exchange rates, poverty rates cannot be compared with poverty rates reported previously for individual countries.

As a result of revisions in PPP exchange rates, poverty rates cannot be compared with poverty rates reported previously for individual countries. Data showing as 2.0 signifies a poverty rate of less than 2.0 percent.
