Dot Distribution Map

Advantage : Dot maps give a better representation of the distribution of the population Disadvantage : Almost impossible to get actual values of population or population density from it.

Choropleth Map Population Density

Disadvantages Although choropleths give a good visual impression of change over space there are certain disadvantages to using them: Although choropleths give a good visual impression of change over space there are certain disadvantages to using them: They give a false impression of abrupt change at the boundaries of shaded units. They give a false impression of abrupt change at the boundaries of shaded units. Choropleths are often not suitable for showing total values. Proportional symbols overlays are one solution to this problem. Choropleths are often not suitable for showing total values. Proportional symbols overlays are one solution to this problem. It can be difficult to distinguish between different shades. It can be difficult to distinguish between different shades. Variations within map units are hidden, and for this reason smaller units are better than large ones.
