income of $1.90/day per person. The other is at $3.20/day. By comparison, the U.S. 2015 poverty line of $20,090

annually for a family of three works out to $18.35 per person per day.

Clearly, many people around the world are far poorer than Americans, as Table 15.2 shows. China and India both

have more than a billion people; Nigeria is the most populous country in Africa; and Egypt is the most populous

country in the Middle East. In all four of those countries, in the mid-2000s, a substantial share of the population

subsisted on less than $2/day. About half the world lives on less than $2.50 a day, and 80 percent of the world lives

on less than $10 per day. (Of course, the cost of food, clothing, and shelter in those countries can be very different

from those costs in the United States, so the $2 and $2.50 figures may mean greater purchasing power than they

would in the United States.)
