#7 HDI and Sub Saharan Africa

The variables on the HDI include life expectancy, GDP per capita, access to clean water, and children underweight for their age.

The geographic pattern is that the HHD tend to be the "Western world" and some of the Middle East. The MHD include South America, Middle East, Eastern Europe and some of Asia.

Sub Saharan Africa is probably so low because they are some of the poorest countries, which effects alot of the variables. Many of the countries do not have ports, or access to trade, and even the ones that do, do not have much to trade with the Western world. I think another factor is the way that SUb Saharan Africa was colonized. Most of the natives were treated as second class, and not allowed education and properity.
