Final answer:
Approximately 17 percent of the developing world's population lived in poverty with an income of less than $1.25 per day in 2005.
Step-by-step explanation:
According to the World Bank estimates, approximately 17 percent of the developing world's population lived in poverty with an income of less than the equivalent of $1.25 per day in 2011 (World Bank 2014a). This is a significant decrease of 26 percent compared to ten years ago, and an overall decrease of 35 percent compared to twenty years ago. It is important to note that this data is from 2011 and may have changed since then.
The World Bank's poverty estimates are derived from household surveys and national income data, providing a comprehensive view of economic conditions across various countries. The 41% figure underscores the magnitude of poverty in the developing world at that time and highlights the global challenge of addressing economic disparities and improving living standards for a substantial portion of the world's population. Since then, efforts have been made to reduce global poverty through targeted development initiatives and sustainable economic growth.
