Poverty
Measuring poverty
According to Chen and Ravallion, about 1.76 billion people in developing world lived above $1.25 per day and 1.9 billion people lived below $1.25 per day in 1981. The world's population increased over the next 25 years. In 2005, about 4.09 billion people in developing world lived above $1.25 per day and 1.4 billion people lived below $1.25 per day (both 1981 and 2005 data are on inflation adjusted basis). Some scholars caution that these trends are subject to various assumptions and not certain. Additionally, they note that the poverty reduction is not uniform across the world; economically prospering countries such as China, India and Brazil have made more progress in absolute poverty reduction than countries in other regions of the world.
