A choropleth map is a type of thematic map. Areas are shaded or patterned in proportion to the variable being displayed. There are many different types of choropleth maps, all having different ways of portraying the variable. This choropleth map shows the deaths per 1000 live births in Australia. The deaths are represented by the shading, the darker the shading, the higher the death rate is and vice versa.
