===Global poverty line===
The global poverty line is a worldwide count of people who live below an international [[poverty line]], referred to as the dollar-a-day line. This line represents an average of the national poverty lines of the [[least developed country|world's poorest countries]], expressed in international dollars.  These national poverty lines are converted to international currency and the global line is converted back to local currency using the PPP exchange rates from the ICP. PPP exchange rates include data from the sales of high end non-poverty related items which skews the value of food items and necessary goods which is 70 percent of poor peoples' consumption.<ref>{{Cite web|url=https://www.carnegiecouncil.org/publications/archive/policy_innovations/index|title=Policy Innovations Digital Magazine (2006–2016) |website=Carnegie Council for Ethics in International Affairs |language=en-US|access-date=2019-09-27}}</ref> Angus Deaton argues that PPP indices need to be reweighted for use in poverty measurement; they need to be redefined to reflect local poverty measures, not global measures, weighing local food items and excluding luxury items that are not prevalent or are not of equal value in all localities.<ref>[http://www.princeton.edu/~deaton/downloads/presidential%20address%2019january%202010%20all.pdf Price indexes, inequality, and the measurement of world poverty Angus Deaton, Princeton University]</ref>
