Bivariate Choropleth Map

Bivariate choropleth maps are maps which two different sets of data which relate well together. Often different colors are used for the two data sets. In this map it shows the death rate of all the countries in Africa and contrasts that against the number of the people recorded living with HIV/AIDS in the countries. Often bivariate maps try and draw a correlation and thus a conclusion between two unrelated data sets. Some times it may be true and others they may be unrelated as one can see in this map. They are used mostly in the education and health fields and because of what they can show, they are invaluable.
