This map shows the information about population density in June 2010 in Australia. To begin with, we can see that there are several sections in this map, that is, over 100 people per square kilometers, 10 to 100, 1 to 10, 0.1 to 1 and less than 1. According to the graph, in the middle area of this picture, the majority is covered by the color indicating less than 0.1 people per square kilometers. Last but not the feast, in Tasmania, it is mainly covered by the color indicating there are 0.1 to 1.0 people per square kilometers. In conclusion, I think this is a very useful graph, and it helps to understand population density in June 2010.
