Standardized choropleth maps take the information found in a choropleth map and place it in a specific region. In this map the absolute value of population is depicted in a more concentrated area. The information is more easily understood and can be more detailed in contrast with a larger scale over the entire world. In these maps it is more obvious to tell that one county is more dense than the other.
