Absolute poverty measures vary from country to country. For example, in 2017, the poverty line in the United States for a family of four was an annual income of $24,600, but economists often use a much lower threshold income of $1.25 per day when calculating the rate of poverty in poor countries. Using this $1.25-per-day measure of the poverty line, which of the following regions had the largest percentage decrease in the percentage of the population in poverty from 1970 to 2010?

• Latin America

• sub-Saharan Africa

• East Asia

• the Middle East and North Africa
