QUESTION: Global income inequality

question / pregunta: 

I am an educator at an international development NGO, seeking information for an activity trying to communicate to high-school and college students about global income inequality. I am looking for up to date statistics on global income distribution (per capita). Most of what I have found has been country break downs (i.e. per capita income in Algeria is X) but I'm looking for - top 10% in the world earn X, next 10% earn Y, etc. Any ideas? Many many thanks


Though I am not sure about finding date that gives the breakdown just as you describe, there are two sources that come to mind that could be useful resources.

One is the United Nation Development Reports statistical data, which tracks progress on the millenium development goals. Here is the link for getting data by indicator -- you may already know about these reports.

The second is a cool tool created by the organization called Gapminder -- it has an interactive statistical visualization using the UN data called Gapminder World
