Should the $1.90 a day poverty line be used to plan programs and policies in a specific country?

While the global extreme poverty rate may not be dramatically different after the adoption of the new PPP and poverty line, some regional and country rates may fluctuate considerably.

It is important to note, however, that the global poverty line is used primarily to track global extreme poverty, and to measure progress on global goals set by the World Bank, the United Nations, and other development partners. A country’s national poverty line is far more appropriate for underpinning policy dialogue or targeting programs to reach the poorest. For example, in a middle-income country, where the national poverty line is at $4 a day, the global poverty threshold may be less relevant than in a poorer country where the national line is at $1.65 or similar.
