The map pictured below is from http://www.worldmapper.org/. It depics how many people in the world are infected with HIV or human immunodeficiency syndrome. I find it very interesting that Africa, on average, has the highest Total Fertility Rate (TFR) and the highest percentage of HIV infected individuals. Consequently, Africa also has a high mortality rate for children ages 1-4. The infected individuals pass on the virus to their offspring. This accounts for the increase of HIV and child mortality along with an increase in the TFR.

Increasing Population -Yemen:
Nice selections in relation to the population pyramids. Yemen is one of the least developed countries on earth and Austria one of the wealthiest.
